Many refrigerator models are equipped with an indication panel. Knowing the meaning of the refrigerator indicators, you can independently determine its condition.
The display panel contains red, orange and green lights. The green light is an indicator of the operation of the refrigerator and freezer compartments. This indicator lights up constantly, indicating the correct operation of the refrigerator. When the freezing mode is turned on, the orange light turns on. If the red light on the refrigerator is on, this means that the temperature in the refrigerator has begun to rise.
Typically, the red light is the biggest concern for refrigerator owners. But it does not always indicate a malfunction. There are cases of temporary temperature changes to which the refrigerator reacts by turning on a red indicator.
Often the red light on the refrigerator lights up when the device is turned on after defrosting (the refrigerator was defrosted and warmed up to room temperature). The indicator will remain on until the temperature reaches the set cooling point on the thermostat. This will happen within three to six hours.
The red light on the refrigerator may flash for several minutes after the door is opened, thus reacting to an increase in temperature.
The battery light comes on why the battery light on the panel is on
Let's start with the fact that every driver, when starting the engine, paid attention to the red battery icon that appears when the key is turned in the ignition.
In this case, the battery indicator lights up until the engine starts. In other words, normally the battery icon goes out after the engine starts.
So, when the engine is not running and the ignition is turned on, self-diagnosis of all vehicle systems occurs before starting. After such a check, some indicators go out after a short period of time, others go out after the engine starts. The same thing happens with the battery. If everything is normal with the battery, and while the engine is running, it is being charged, then the battery lamp lights up for a short amount of time (a few seconds) and then goes out.
In other words, the circuit is such that after turning on the ignition, voltage is supplied through the fuse to the battery warning lamp (battery charge lamp) on the instrument panel.
The voltage then passes through the diodes, relay regulator, brushes, slip ring and winding. After starting the engine, the voltage at the terminals of the battery light is equalized, and the light goes out. At the same time, the battery is being charged. If the battery on the panel lights up constantly or such an icon lights up periodically, then this indicates a malfunction.
So, to understand why the battery light is on, you need to look at the reasons why the battery light may come on. Let us immediately note that this indicator monitors the connection between the battery and the generator. Let's figure it out.
The battery charging light is on: possible causes of the malfunction
As you know, a car battery is closely connected to the generator. To start the engine, electricity from the battery is supplied to the starter, but after the internal combustion engine starts working, the current is generated by a generator that spins from the running engine.
In this case, the battery is in recharging mode from the generator. Moreover, if the engine speed increases, then the voltage produced by the generator also increases. To prevent overcharging the battery or supplying too high voltage, there is a relay regulator on the generator.
The main task of the device is to ensure that the current from the generator to the battery is always optimal, that is, the voltage does not depend on engine speed. This makes it possible to constantly obtain and maintain the required voltage.
So, the battery light most often comes on when the battery is not being charged from the generator. It turns out that the driver started the car from the battery, the engine started running, but the battery icon is on (the battery light does not go out).
As a rule, the list of frequent breakdowns includes:
- problems with the relay regulator;
- failure of the diode bridge;
- the alternator belt is broken, poorly tensioned or slipping;
- severe play in generator bearings and wedging;
- blown fuses;
- poor contacts at the battery terminals, at the generator output, on the ground wire;
- generator circuit open;
- wear of generator brushes or brush holders;
- there may be problems with the ignition switch;
Where to go if the lock or key is on fire?
What to do if the lock, key or other malfunction indicator on the washing machine is on, but the machine does not work? It is impossible to independently determine the cause of the breakdown. The fact is that there are many reasons why the lock is on. Diagnostics should be carried out by a technician who has experience working with devices from this manufacturer.

Designation of light bulbs and sensors on the tidy
Reasons for the discharge of the VAZ 2110 battery
First, let's get acquainted with the location and description of the components of the dashboard in the Lada Vesta:
Tachometer. Thanks to this device, the driver knows what the crankshaft operating frequency is, that is, at what speed the engine operates. Do not allow the instrument needle to move into the red zone, as this may lead to damage to the power unit. If you press the gas pedal to the floor, while the speed exceeds 6200 rpm, the fuel supply will be limited. Experts also recommend not allowing the engine to operate in a dangerous mode, when the speed is less than 800 per minute. "Pedal adjustment" indicator. The seat belt icon is always on if the driver or passenger is not fastened. Indicator. If it appears for no reason, the problem may be a failure of the airbag sensor or its poor contact with the electrical network. A backup light bulb can be connected when installing additional devices or systems. Brake failure indicator; when it appears, you should stop the car and check that the brakes are working properly. The trunk door is unlocked icon; when it appears, you should check the trunk. Unlocked hood symbol. If it starts to light up on the dashboard, while the hood is normally closed, you need to check the functionality of the sensor. Speedometer
This device is considered one of the main ones, since the driver pays attention to it more often than others. The device is used to demonstrate the speed of movement. The hazard warning light icon always flashes when the hazard lights are activated. Unlocked doors symbol
If the car starts moving with one or more doors open, a corresponding light will appear on the dashboard. Cruise control system indicator. The speed limiter indicator appears if the driver exceeds the permissible speed. This device indicates the temperature of the antifreeze in the cooling system. If the indicator fails, the vehicle cannot be operated as it reports the engine temperature. If this value exceeds the permissible value of 115 degrees, the light will light red without interruption, and the buzzer should also sound briefly. At high temperatures, the engine may simply fail. Icon of the standard anti-theft system - immobilizer. Icon for turning on side lighting. Symbol for switching on low beam. LED high beam activation icon. The indicator for turning on the front PTFs always appears when they are activated. The icon for turning on rear-mounted foglights is similar. ESC light - electronic stability control system. The ESC OFF symbol indicates that the system is turned off. The fuel level sensor in the tank is used by the driver to guide him when he needs to refuel the car. The reserve fuel volume activation icon appears when there is little gasoline left in the tank. LCD display with main parameters and options. The right turn signal icon stops flashing after the maneuver is completed. Left turn signal activation symbol. ABS system activation lamp.
The battery icon may always appear when the ignition is turned on, but should disappear after starting the engine. If the indicator remains on, this indicates the need to charge the battery or diagnose the generator unit. The light indicator for emergency low tire pressure receives data from the corresponding sensors installed in the wheels. Symbol of problems with the gearbox. Icon of faults detected in the operation of the motor. There can be many reasons; when a symbol appears, more detailed diagnostics are required. Electric power steering controller. Symbol of emergency low oil pressure in the internal combustion engine. It also always appears when the ignition is turned on and disappears after the engine starts (the author of the video is Yuri T*********O).
What kind of service is this?
Most modern cars are equipped with special electronics that allow the driver to be informed about a problem in a timely manner. One of them is “Check Engine”, it is responsible for the composition of the fuel mixture, speed, ignition and much more. It is for this reason that it is difficult for an inexperienced user to determine what happened to his car even after the light comes on. The main causes of malfunction include:
- low-quality fuel found at domestic gas stations;
- faulty spark plugs;
- Lambda probe;
- problems with injectors;
- high voltage wires;
- fuel filter or gasoline pump;
- catalyst;
- problems with the ignition coil.
Sometimes the Checkengine indicator may light up for a while and then go out again. Most likely it is a fuel problem. If the indicator does not stop lighting, then it cannot be ignored.
The engine is the heart of any car, so you need to treat it as such. If a problem is not noticed in a timely manner and not corrected, it can lead to engine failure and costly repairs. That's why it's so important to contact a mechanic right away if the Check Engine light . At the same time, the traction control indicator may light up or the airbag system indicator may be activated.
How to turn off the tire pressure indicator
Review of the instrument panel VAZ 21074 injector
So why might your tire pressure light come on?
- One of the wheels is lowered (if a system with a sensor in each wheel will tell you which one, an indirect measurement system - you need to check each one). The indicator will turn off on its own after pumping or repair.
- Malfunction of the tire pressure sensor - the error can be corrected by replacement.
- Initialization failure - can be resolved by re-initializing the on-board computer with sensors.
- We carried out a seasonal replacement of wheels, but the replaced set did not contain pressure sensors. The computer thinks they are faulty. It can be treated by installing sensors or ignoring the warning.
Some manufacturers can use diagnostic equipment to activate or deactivate the TPMS system, but this must be done extremely carefully, since changing just one bit unknowingly can lead to disastrous consequences for the entire BCM unit.
Difference in color indication
Removing the instrument panel assembly with heater Lada Kalina
Shield signs are important information. It is transmitted in a variety of ways, such as blinking, but usually color should be taken into account when assessing the condition of the engine and systems. What notations can be compared to reach the correct conclusions?
- Green or blue color – normal operation of the node or system.
- Orange or yellow color – urgent service required.
- Red color – a breakdown has occurred.
When the light bulbs come on, you will have to immediately deal with the problem. Often delays lead to serious consequences, in particular, to the mandatory replacement of a particular part. You shouldn’t wait for such a moment, as certain types of engine repairs cost a pretty penny.
Connection diagram
The classic connection diagram for a battery charging light is the diagram shown in the figure:
When the ignition switch contact group K is turned on, positive battery voltage is supplied to the left terminal of the battery charging lamp.
If the generator does not rotate, there will be a low voltage at the right terminal of light bulb L. It will glow. At the same time, the lamp provides starting current to the generator armature. In such a switching circuit, if the light bulb is faulty, there will be no starting armature current, and the generator will not begin to supply voltage for charging after the engine starts.
After starting the car engine, voltage from the additional rectifier bridge will be supplied to the right terminal of the light bulb L. There will be no potential difference at the terminals of the light bulb, and the indicator goes out.
In modern cars, to provide starting current, even more reliable shunt resistors are installed parallel to the charging lamp, which ensure charging even when the lamp is faulty.
In most cars manufactured after 2000, the battery charging lamp is controlled by an electronic unit on the dashboard. A digital circuit measures the voltage of the on-board network and gives a signal to turn on the indicator if it does not comply with the set values.
Cars from BMW, VW, AUDI and other “reputable” manufacturers are equipped with a battery charging control system, which allows you to increase the battery life and avoid boiling and overcharging phenomena.
In such schemes, the battery charging lamp is controlled by these systems, the operating algorithm of which is quite complex. This has its advantage: the system accurately diagnoses the location of the fault. If the charging indicator lights up, just connect computer diagnostics, and it will independently determine the specific location or node of the fault.
In all other cases, if the battery charging lamp does not work correctly, it is necessary to determine the malfunction using control and measuring devices.
Description of indicators
We will consider the indicators in the order in which they are located from left to right on most popular models of Wi-Fi routers.
Please note that their placement may differ on some models, but their purpose is exactly the same.
Some bulbs may not be available in different models; we will describe them at the end.
Power
Power indicator. As the name implies, it is responsible for powering the router. Everything is simple with it: if the light is not on, then the power is not supplied, and if it is on, then the router is connected to the power supply.
WLAN
Wireless network indicator. Provides information about Wi-Fi operation. If it is not lit, then the wireless network on your device is disabled. It is turned on in the device’s web interface. If the light is on, the Wi-Fi network is turned on, but there are no active connections at the moment. If the light blinks, data is being exchanged between the router and the client device. There may be two Wi-Fi indicators if the router supports data transmission in different bands - 2.4 GHz and 5 GHz. In this case, each light bulb is responsible for the state of the network in a specific range.
WAN
Internet connection indicator. It is indicated by a globe icon.
Responsible for the state of your router’s connection to the provider’s cable line:
- If the light is off, the cable is not connected or there is no signal.
- If it lights up, the connection is established and the Internet is connected.
- Flashing – data is being exchanged with the network.
The light may also light or flash orange (yellow or red on some models). This means that the connection is established, but there are problems with connecting to the Internet. In this case, the Internet does not work.
LAN
Most often there are four of them - according to the number of network ports intended for connecting client devices using a cable. On some budget routers there may be two ports and, accordingly, indicators. Sometimes there are more than four ports and indicators. They work exactly the same as the Wi-Fi indicator. If a cable is connected to the port, but the connection is inactive, the light is on. When data is being exchanged, the light blinks. If nothing is connected to the port, there is no indication. Sometimes it happens that a router has several LAN ports, but there is only one indicator. In this case, the indication turns on if a device is connected to at least one of the ports.
USB
Some routers have one or two USB ports for connecting 3G/4G modems, flash drives, printers and other devices.
The USB light works as follows:
- Off – nothing is connected.
- Flashing – the device is being connected, the device is not recognized.
- On – the device is recognized and connected.
WPS
Not available on all models, and is responsible for connecting devices via WPS. For routers that have a separate WPS connection button, the indicator can be combined with it. If it blinks slowly, the connection process is in progress. If it flashes quickly, the connection has failed or the time to establish the connection has expired. When the device has connected successfully, the light is on without blinking.
SYS
Usually indicated by a gear sign, it is not present on all router models. This is a system indicator that reports errors in the operation of the device. It has three modes. If the light blinks, it means the device is working normally. If it is not lit, an error or malfunction has occurred. When you turn on the router, the light does not blink. This means that the device is loading. However, if more than a minute has passed and the indicator remains on, this also indicates a system failure.
LOS and PON
If the router supports GPON technology, then they are responsible for connecting to the provider. Such a router is connected using optical fiber rather than an Ethernet cable. Therefore, LOS and PON appear instead of the WAN indicator. LOS is responsible for the presence of a connection, and PON is responsible for registration in the provider’s network. Some models do not have LOS. In this case, its functions are performed by PON. Read more about these light bulbs here.
Let's look at different situations in which the battery light comes on.
- Situation one - the on-board voltmeter shows the charge, the battery light does not light up, the multimeter shows 12V at the battery terminals, while the battery itself is completely discharged.
Treatment: We strip the high voltage terminals and wires, after which we measure the voltage again. If this does not lead to anything, check the voltage at the “30” terminal of the generator. Connect one electrode of the multimeter to the generator terminal, the second to ground. If in this case the voltage is slightly higher than on the battery, “stripping” the “30” terminal. If necessary, change the wire that goes from the generator to the battery.
- Situation two - the light and the light indicate charging, but the battery is discharged. The voltage on the battery is normal (
14V), but when there is a load (signal, headlights, etc.), the charging arrow jerks to the extreme left position. The reason is poor tension of the generator belt, or a problem with the pulley or bearing itself.
- In addition, the cause of the above situation may be a breakdown of one of the diodes or a break in the stator winding. Do the following - turn off the ignition, then check the diodes with a multimeter; if a breakdown is detected, replace them.
- It would be a good idea to check the generator brushes. To do this, simply remove the brushes and check their length, if the length is less than five mm. I recommend replacing the generator brushes.
- Situation three - after turning the key in the ignition, the battery lamp does not light up, while the charge sensor does not work, and the battery does not charge. The most likely cause is a blown fuse. It is designated “F10”, its rating is 10 Amp. If after replacing a new fuse you do not see any result, the reason may lie in the lock itself or the ignition relay.
- Situation four - after turning the key there is no charging, but all devices are functioning, the battery light does not light up.
Treatment: Remove the wiring from terminal “61” of the generator, and then connect it directly to the negative (that is, to the body). If after this the lamp lights up, the reason is in the excitation winding of the generator.
The reason may also be poor contact in the connector. It is necessary to clean everything properly and check the result; if it is not there, it is very possible that the lamp has burned out. If the problem is not in the light bulb (it burns dimly or intermittently), then other indicators will also light dimly or intermittently; if this only happens with the battery indicator, then perhaps the reason is in the light bulb itself.
- Situation five - after turning on the ignition, the battery light comes on, and after starting the engine it does not go out, while charging is either intermittent or does not exist at all. The reason for this behavior may be poor contact of the wire with the connector on the dashboard.
After all the above checks, check the relay regulator and apply voltage to its contacts. Check the voltage on the brushes, if it is 12V, the relay is working properly. Otherwise, replace the relay regulator.

Other breakdowns and their solutions
If the refrigerator does not turn off for a long time, but does not freeze very well, then the cause may be clogged capillary tubes. Oil and freon, circulating through the system, interact with each other and form paraffins, which gradually clog the capillary tube. To eliminate the cause after defrosting, a specialist can change the filter drier, replace the tubes or refill the refrigeration unit.
In some cases, the indicator, on the contrary, does not light up, but the equipment works without failures, then repair of the indicator panel will be required.
To prevent the red indicator from lighting up in the future, you must set the temperature correctly and periodically defrost the freezer. You must ensure that the refrigerator door is always tightly closed. It is often not recommended to open it.
A few words about how the battery-generator tandem works
Everyone, even a novice driver, knows that the battery interacts with the generator. After starting the engine, the battery goes into constant charging mode. After the engine speed increases, the voltage at the generator output also increases, which is not a “hum”.
In order to prevent the above described, a small relay-regulator is installed in the rotor excitation circuit, the task of which is to reduce the current to the optimal level, regardless of the engine speed. As a result, the voltage is maintained at the required level. The battery light comes on when there is no charging from the generator.
So, let's simulate the situation. You started the engine, but the battery light did not go out. What's the matter?
- Faulty relay-regulator, diode bridge;
- Poor tension of the generator belt, critical wear or belt slippage. Wear (play) of the generator bearing;
- Blown fuse or poor contact;
- Poor contact at the battery terminals, at the generator terminal or at the ground wire;
- Open circuit of the generator excitation circuit, serious wear of the generator brushes or brush holders;
- Wearing out the ignition switch is an option, but in this case several lights will light up at once.
The need for a voltage regulator
Each generator has two required windings: on the stator and on the rotor. The excitation winding is a rotor winding, because it is from the moving magnetic field that electricity is generated. To form a magnetic field, voltage will need to be applied to the rotor turns.
The installed voltage regulator in the power circuit of the excitation winding fulfills its mission, although at first glance it may seem that it is more necessary for the stationary part. However, the output voltage depends on the magnitude of the magnetic field. In such a situation, it is possible to stabilize the power supply in the rotor winding circuit and thereby get rid of possible output fluctuations.
Types of steering racks
- “Mechanical” steering racks were the first to appear on cars and are still found in some new cars in the economy segment. Here the driver himself turns the wheels, leaning hard on the steering wheel. The toothed gear drives the rack and pinion, moving the tie rods left or right.
- Steering rack with hydraulic booster. Here a hydraulic pump powered by the engine comes to the driver’s aid. It moves the steering rack using oil.
- Electrically powered rack. Instead of oil, an electric motor works here, which can be installed on the steering shaft, on the steering gear or on the rack.
We list the most common signs of a faulty steering rack, indicate the causes of problems and repair methods.
On the list of problems:
- knocking in the steering rack, which can appear on bumps and disappear on a flat road or when turning;
- vibrations on the steering wheel while the car is moving;
- unexpectedly “tight” steering wheel when turning sharply;
- extraneous sounds coming from the rack while the car is moving, especially distinct when driving on a bad road;
- spontaneous turning of the steering wheel;
- excessively slight movement of the steering wheel or its play;
- complete absence or weak return of the steering wheel to its original position;
- discrepancy between steering wheel rotation and wheel rotation angle.
Closures
Samsung laptop won't turn on? The power indicator is on, is the cooler working? The next scenario is one of the rarest. And it is almost impossible to diagnose it yourself.
The problem under study can appear when the south or north bridge in the laptop is damaged. Why does this happen? Bridge problems are caused by different methods. For example, through a short circuit due to a temperature difference. If, say, the USB port on a laptop is damaged due to this, it is likely that the problem under study will occur.
There is only one method of struggle - repairing damaged components. The most effective way is to buy a new computer. After all, rarely repaired components on laptops work for a long time. Here, each user independently decides what to do.
How to remove the dashboard of Lada Vesta
It is assumed that the new version of the panel can be purchased and installed on a torpedo. Its price will be approximately 8,000 rubles.
The procedure for removing the dashboard involves the following steps:
- Disconnect the negative terminal of the battery.
- There are two bolts at the top of the panel that hold it in place. They need to be unscrewed using the T20 socket.
- Now you can remove the instrument panel by pulling it towards you so that the latches release.
- Using the T20 socket, unscrew the exposed screws that secure the devices.
- Now you can pull the panel towards you and disconnect it from the wires.
Installation is in the reverse order. The connection diagram should not change.
Problem Laptop battery is connected but not fully charged
Step 1. Check the battery condition
You can check the battery status with the free Battery Health program for iOS or the standard Battery Care utility in devices running Windows 7 and 8.
Three main parameters of battery health are important to us.
- Declared, rated, power. This is the capacity of a new battery when it just left the factory.
- Maximum power. This is the current capacity value.
- Battery wear as a percentage. The higher this value, the higher the need for replacement.
The problem of the charge not reaching the required level is also solved using.
Step 2: Replace the battery (if necessary)
If wear and tear is high, then it is likely the reason for the decrease in battery life. To solve the problem, you will need a new battery; in most models it is removable. In this case, you can change it yourself. In a number of modern compact models, the battery is not removable and replacing it yourself will be more difficult. It is safer to do this at a service center.
Step 3. Diagnostics of programs on the laptop
If the battery diagnostic utility shows no significant wear in Step 1, then the battery is probably not the direct cause of the drop in battery life. The culprit for fast discharge may be some recently installed program that runs in the background and prevents the processor and Wi-Fi chip from switching to energy-saving mode.
Open Task Manager by pressing Ctrl+Shift+Esc and analyze the CPU usage of background programs. Sort the apps in the list by CPU usage and watch for a while. Removing unnecessary programs running in the background will increase battery life.
AirPods light doesn't light up
There are two possible ways of development of events:
- The headphones and case are completely discharged - put them on charge and rejoice!
- AirPods broke (probably some kind of manufacturing defect). It is almost impossible to repair the headphones yourself - we go to an official service center.
That seems to be all.
Although! There is more...
“Non-standard” flashing options for AirPods headphones.
Let's take a look at them!
Instrument panel features
The dashboard of the Lada Vesta contains measuring and control components:
- Fuel level sensor.
- Tachometer.
- Motor heating indicator.
- Speedometer.
The area directly above the steering wheel was selected for their placement.
The main device is the speedometer (from 0 to 200 km/h). Lada Vesta SV Cross vehicles do not accelerate to the maximum value. The engine type does not affect the speed limit. The following indicators and sensors are concentrated directly on the speedometer, which signal certain processes:
- The luggage compartment is not closed.
- Open hood.
- Open door designs.
- Climate control system.
- Turn sensors.
- Speed limiters.
- Emergency alarm.
- Turn indicator.
The on-board computer monitor on the Lada Vesta dashboard is concentrated under the speed scale. The following data is displayed on the screen:
The best choice of tinting is frameless curtains. Best price 1500 per pair. ORDER ON INSTAGRAM
Most recently, AvtoVAZ presented a new type of dashboard for the Lada Vesta, which has undergone dramatic changes in contrast to the previous version. The feasibility of creating a new dashboard is determined by the fact that the manufacturer is preparing a large batch of Lada Vesta cars for export to European countries; it is in European countries that a production car with a new type of dashboard will appear for the first time.
Causes and their elimination
So, if you notice that the red button on your HP printer is lit, which means “Warning” (Canon printer models have an exclamation mark in this situation), then perhaps your printer does not have a cartridge. To fix this problem, you just need to open the printer cover and gain access to the opening intended for consumables. Next, you should remove the special protective film from the new cartridge, and then install it in the opening intended for it until a characteristic click is heard.
If two buttons on the printer panel flash periodically, i.e. green (“Ready”) and red (“Warning”), and at the same time, the reason is that the printing device is going through the initialization process.
If you notice that the green button begins to blink, then keep in mind that the printing device is currently processing data or receiving data. It also happens that the “Ready” light is constantly on, and the “Warning” light only blinks occasionally - such indicator signs indicate a general error in the device or a paper feeding error. This situation is usually accompanied by jammed sheets of paper already caught by special rollers.
If a red light on the device panel periodically starts to glow, this may indicate that the cartridge is not installed correctly. In addition, a similar signal also appears if the access cover to the consumable elements is not closed tightly enough. To fix this problem and return the printing device to working condition, you should remove the cartridge from it and put it back in place.
If the red light on your HP model starts blinking, the problem may be a paper jam. To resolve the problem, remove all loose paper from the special tray, remove the consumables with ink from the printer, and remove all sheets. In addition, this indicator may also blink due to the packaging material not being completely removed, incl. special tape. To completely remove it from inside the printer, open the top cover to access the supply. In addition, packaging bags must also be removed from the input and output trays.
Incorrect operation of the sensors responsible for closing the case may also be reflected in the fact that the “Warning” light on the printer panel is constantly on. If both device indicators are constantly on, this may indicate some serious error, which is unlikely to be eliminated on your own.
It should be added that for printing devices from Canon, a triangle is responsible for displaying the error code. Therefore, if you notice that a triangle with lightning is lit on the printer, then remember the code that will appear on the printer display, and then find its detailed description in the instructions for the device. But on models from Epson, instead of green and red indicators, as well as a triangle, if there is an error, a droplet begins to blink.
For example, if the device’s drop starts blinking when the cartridge is full, then to solve the problem you should reset the “diaper’s” waste ink counter using some utility program, for example, PrintHelp.
Thus, office equipment indicators promptly inform us about the presence of certain problems. Many of them can be eliminated on your own, even without certain skills.
So, if a light on your device starts to light up that was not on before, first read the user manual. But in cases where the reason has not been specifically established, it is better to use the services of a service center, where your device will be carefully examined for the presence of certain defects.
Why is the red light on the refrigerator on?
The LED lights up when the temperature in the freezer compartment rises above the set values (usually -18℃). In some models, the mode when the red light on the refrigerator flashes indicates that “super freezing” or automatic defrosting is turned on. But the red light on the Atlant refrigerator serves precisely to attract attention so that the owner has time to react to the rise in temperature.
- The red light on the refrigerator lights up after defrosting, transporting or turning on for the first time. The device is operating normally. The freezer cools gradually, so sometimes “Attention” lights up on the refrigerator for 8-12 hours after starting.
- An exclamation mark lights up on the refrigerator after adding food. The instructions indicate the permissible daily freezing volume. If you exceed the mass, the temperature in the compartment rises, returning to normal parameters takes from 30 minutes to 3-4 hours. Before adding food, do not forget to turn on the freezing mode (available in Atlant refrigerators and appliances from other manufacturers), then the device will automatically prepare to receive a new batch.
- The signal appears after the door is opened. It is advisable not to open the freezer door for a long time - the flow of warm air increases the overall temperature. 5-10 minutes is a sufficient period for the frost loss alarm to be triggered. Usually the LED goes out after 15-20 minutes.
- “Alarm” lights up on the refrigerator for no apparent reason. If the sign appears suddenly, without opening the doors, adding food and not after defrosting, then (possibly) a breakdown of the temperature sensor, compressor, depressurization of the refrigeration system, or malfunction of the control unit has occurred. The cause must be found and eliminated.
