What s going on with the air conditioner s electric auxiliary heating light

This is normal. It shows that the air conditioner is heating, and the electric heating pipe that assists heating is also working. When the air conditioner with auxiliary heat is heating, on the one hand, the compressor is working, and on the other hand, the electric heating pipe is also working.

Before starting, the 220V power supply is normal, and the compressor is only about 150V at the moment of starting, which is mostly due to the improper selection of the 220V power supply line and the thin cross-section of the wire. In case of this failure, you only need to replace the power cord.

Brand model: Midea air conditioner.

System: KFR-35GW N8XHC1

There are many reasons why the heating lights of the air conditioner flicker, when the external magnetic field interferes; When there is no normal communication between indoor and outdoor air conditioning equipment; When the voltage is too high and the air conditioner is overloaded, in order to protect itself, the indicator light of the air conditioner will also flash all the time; If the current is overloaded, it will also cause the heating light of the air conditioner to flicker.

Solution: 1. For the first two situations, the display board of the air conditioner can be fault-detected. By disconnecting the indoor and outdoor cables, troubleshooting, if this is the kind of fault, you should contact the maintenance personnel in time for repair.

2. In view of the situation that the heating lamp of the air conditioner is flashing due to current overload, the power should be turned off first, and the voltage and other conditions should be detected and repaired.

3. In view of the overload operation of the air conditioner with high voltage, the air conditioner will automatically enter the self-protection state, causing the indicator light to flash. It is necessary to check whether the three-phase power supply is connected correctly, and also check the indoor motherboard and the outdoor detection board, detect a variety of situations, eliminate faults in time, and ensure that the flickering situation of the air conditioning heating lamp is solved.

The reason why the auxiliary heat indicator light of the Gree air conditioner does not light up after turning on the auxiliary heat mode is that the auxiliary heat indicator of the air conditioner is broken or the auxiliary heat function is not turned on.

1. Reasons and solutions for the non-lighting of the auxiliary heat indicator light of Gree air conditioner:

If the electric heating is turned on or not displayed, it may be due to a problem with the display or a dead battery.

Solution: Replace the battery and check the display again.

2. Operation guidelines for the switch of electric auxiliary heat function of ordinary air conditioner:

The electric auxiliary heating function is turned on by default after the air conditioner turns on the heating function, the red light of the electric auxiliary heating is on, the heating is turned on, and the electric auxiliary heating is turned off after reaching the set temperature. If the temperature is not enough, it will be automatically turned on again.

The air conditioner turns on the heat-electric auxiliary heat, and the red light indicates that the electric auxiliary heat is running.

Electric auxiliary heating is a way to convert electrical energy into heat energy to heat, it is similar to electrical appliances such as fast heating and small sun, the inside is a resistance wire, and then after the power is turned on, the electrical energy is converted into heat energy and transmitted to the room.

However, it takes a lot of electricity to convert electric energy into heat energy, and there is a certain safety risk for the air conditioner to install the heating wire, if the quality is not up to standard, there may be an accident of melting parts or burning at high temperature, so only when the air conditioning heating can not meet the needs of the room, the electric auxiliary heating will be turned on. In general, it is not used.

Auxiliary heating: When the weather is particularly cold, the efficiency of the compressor is reduced, and the temperature of the hot air sent out is not high enough, and there is a row of electric heating pipes at the air outlet of the indoor unit to heat the temperature of the sent air.

Use, after turning on, the air conditioner display shows the current temperature value, plus and minus signs to control the temperature level, mode: choose winter heating, or summer cooling, fan, dehumidification, look at the remote control display display icon. Sweep the wind left and right, and there is a prompt on the up and down sweep buttons.

There are conditions for the auxiliary electric heating of the air conditioner to be turned on, such as the compressor operation, the internal fan operation, the heating mode, the internal coil temperature, the set temperature, the room temperature, etc.

The air conditioner's electric auxiliary heating light is usually on because the air conditioner needs to use the electric balance auxiliary heating function to provide a higher indoor temperature. Electric auxiliary heating is an auxiliary heating method used in a low temperature environment, which can improve and improve the heating effect of air conditioning. When the indoor temperature is lower than the set temperature, the air conditioner will automatically start the electric auxiliary heating function and light up the electric auxiliary heating lamp at the same time.

Under normal circumstances, when the indoor temperature reaches the set temperature, the electric auxiliary heating function will be automatically turned off, and the electric auxiliary heating lamp will also be extinguished. If the electric auxiliary heating lamp is always on, it may be that the air conditioner is faulty, and it is recommended to contact the technical staff of the shed for maintenance in time.

The light on the electric auxiliary heating light of the air conditioner usually appears when the heating mode is used for electric heating. In some low-temperature environments, the air conditioner may need to use electric heating to enhance the heating effect, and the electric auxiliary heating lamp will be turned on. Under normal circumstances, when the air conditioner reaches the set temperature, the electric auxiliary heating lamp will be automatically extinguished.

If the electric auxiliary heating lamp is always on and the air conditioner has not yet reached the set temperature, then there may be the following problems:

1.The pipeline between the outdoor unit and the indoor unit of the air conditioner is blocked or fluoride leakage, resulting in poor heating disturbance and burial effect.

2.The sensors inside the air conditioner are damaged or malfunctioning, and the indoor temperature cannot be sensed properly.

3.There are problems with the air conditioner itself, such as imbalance in the air conditioning system, damaged compressor, etc.

If you encounter this situation, it is recommended to contact a professional maintenance personnel for inspection and repair.

The electric auxiliary heating light of the air conditioner is on, indicating that the air conditioner is using the electric heating function. When the outdoor temperature is too low or the indoor temperature is too low, the air conditioner will automatically start the electric heating function, and the electric auxiliary heating lamp will light up to remind the user.

When the air conditioner turns on the electric auxiliary heating, if the indoor temperature is lower than the set temperature, the air conditioner will activate the electric auxiliary heating function to heat the indoor air. During this process, a red light will be displayed on the panel of the air conditioner, which is normal, and the air conditioner is heating up.

It should be noted that electric auxiliary heating is an auxiliary heating method, which is generally only used at extremely low temperatures or under special circumstances. If electric auxiliary heat is used for a long time, it will increase the energy consumption and use cost of the air conditioner, and also affect the service life of the air conditioner. Therefore, when using the air conditioner, you should choose the appropriate temperature and mode according to the actual needs, and avoid excessive use of the electric auxiliary heating function.

In the heating mode of the air conditioner, if you turn on the electric auxiliary heating function at the same time, it may cause the air conditioner to display a red light. This is due to the fact that the electric auxiliary heating function requires additional power support, and the current power used may not be sufficient, thus causing the air conditioner to display a red light.

You can check the specific meaning of the red light and how to solve the problem according to the instruction manual or operation manual of the air conditioner. In general, there are a few things you can consider:

1.Disable Electrically Assisted Heating: If you have only enabled the Electrically Assisted Heating function to enhance your heating, you can try turning it off and using the heating mode alone for heating.

2.Adjust the temperature setting: If the temperature set is too high, it may cause the aircon to not work properly. Try lowering the set temperature and see if the air conditioner is running normally.

3.Clean the aircon filter: A clogged filter will affect the heating effect of the aircon. Please clean the air conditioner filter regularly to ensure smooth air circulation and good heating effect.

4.Check the power supply**: If the air conditioner and electric auxiliary heating function use more electricity than the local grid can provide, then the air conditioner may not work properly.

Please check whether the power supply is stable and make sure that there is no problem with the circuit connected to the air conditioner and the electric auxiliary heating function.

If you still can't solve the problem, it is recommended to contact the aircon after-sales service center or professional repairers for inspection and repair.
