What s the matter if the Gree air conditioner doesn t heat up

Check the following conditions: The mode setting is wrong, the temperature and wind speed are not set reasonably, please select the mode again, set the appropriate temperature and wind speed The filter screen is dirty, the air inlet and outlet of the indoor unit are blocked, and the angle of the air deflector is too small, please clean the filter, remove the obstruction of the air outlet, and adjust the angle of the air deflector The doors and windows, exhaust fans, etc. are not closed, resulting in poor room insulation effect, please close the doors and windows, exhaust fans, etc. The room area is large, the air conditioner is small, it is recommended to increase the wind speed When heating, the air conditioner electric auxiliary heating function is not turned on, and the air conditioner electric auxiliary heating function is turned on.

1. It may be that the wind speed is too low. If the wind speed of the air conditioner is too low, it will definitely have a great impact on the rapid improvement of the heating effect of the room, it is recommended that you try to turn on the wind speed of the air conditioner when using the air conditioner, do not be afraid that this will waste electricity, a comfortable environment is more important than anything else.

2. It may be that the external ambient temperature is too low. We have mentioned this problem many times, this is a hard injury, the heating effect of the air conditioner will be greatly reduced when the temperature reaches 0 degrees, the -5 ° fixed frequency machine can not start normally, and the inverter can not start normally at -14 degrees, so other heating equipment is needed at this time.

3. It may be that the room is too large. The room is too large is a problem that many users tend to ignore when purchasing air conditioners, 4, it may be that R22 is insufficient, R22 is a kind of fluorine, and it is also the most used one in air conditioning.

5. The auxiliary heat is not turned on or there is no auxiliary heat.

The main reasons and solutions for Gree air conditioner not heating are as follows:

1. Insufficient refrigerant for air conditioning, that is, lack of fluorine.

The lack of fluoride in the air conditioner will not only cause the air conditioner not to refrigerate, but it may also cause the air conditioner to not heat up.

Here's how to repair it:

First check the cause of the lack of fluoride in the air conditioner, and then repair and add fluoride. If the fluorine is consumed during normal air conditioning operation, only the air conditioner needs to be fluoridated; If the lack of fluoride caused by the leakage of the air conditioner is required, it is necessary to detect the leak, fill the leak, and add fluoride to test the machine.

2. The air conditioner is too dirty, resulting in pipeline blockage.

The phenomenon of dirty blockage of the air conditioner will reduce the use effect of the air conditioner, and the heating or cooling of the air conditioner will be reduced.

Here's how to repair it:

Clean the air conditioner regularly, especially the filter in the air conditioner room, we should clean the filter every month to ensure that the air conditioner will not be blocked by dirty dust. In addition, the air conditioner should be thoroughly cleaned to improve the use of the air conditioner.

3. The power supply voltage of the air conditioner is insufficient.

When the air conditioner's mains voltage is insufficient, it is likely to cause the air compressor or other components to work less efficiently, which will lead to poor cooling and heating capacity.

Here's how to repair it:

To detect the power supply voltage of the air conditioner, if it is not within the normal range, you need to contact a professional maintenance personnel for maintenance.

4. The four-way valve of the air conditioner is faulty.

The reason why the air conditioner can heat normally is very important to the relationship with the four-way valve. If the four-way valve of the air conditioner has a fault, such as air collusion and non-reversing, it will directly affect the heating effect of the air conditioner, so the air conditioner only blows air and does not heat.

Here's how to repair it:

After determining that the four-way valve of the air conditioner is faulty, replace the four-way valve of the air conditioner.

5. The indoor temperature sensor of the air conditioner is faulty.

If the indoor temperature sensor is damaged, the air conditioner will not be able to detect the normal temperature, which will cause the air conditioner to not heat normally.

Here's how to repair it:

After determining that the air conditioner room temperature sensor is faulty, replace the temperature sensor.

The reasons for the sudden failure of the Gree air conditioner to heat are as follows:

1. When using the air conditioner, the user does not pay attention to the maintenance of the air conditioner, which will easily lead to the accumulation of more and more dust on the air conditioner filter. When the dust on the evaporator and condenser of the air conditioner is too thick, it will affect the heat exchange effect of the air conditioner, resulting in the decline of the heating effect of the air conditioner.

2. When using the air conditioner, if the user sets the temperature of the air conditioner too low when setting the temperature, the user will feel that the air conditioner is not refrigerated normally during the heating process of the air conditioner, and thinks that the air conditioner cannot heat normally.

3. When purchasing air conditioners, users do not choose air conditioners according to the size of their rooms, which ultimately leads to the fact that the power of the purchased air conditioners is too small to achieve the effect of heating when the room is too large.

4. Check whether the indoor power supply voltage is normal. When the power supply voltage is abnormal or unstable, the voltage is too low, which will cause the compressor to work abnormally after the air conditioner is started, and the heating of the air conditioner will also be affected.

5. The role of air conditioner in the operation of air conditioner is very large, whether it is refrigeration or heating, and when the air conditioner refrigerant leaks or is used up, it will cause Gree air conditioner not to heat.

6. The failure of the air conditioner defrosting controller will also cause the Gree air conditioner to not heat, and the failure of the defrosting controller will make the air conditioner unable to enter the defrosting state, which will lead to frosting of the evaporator in the heat pump heating process, which will affect the efficiency of the heat exchange rate of the air conditioner and lead to insufficient heating of the air conditioner.

Due to the many and complex reasons why Gree air conditioners cannot be heated, it is best for users to contact Gree after-sales service as soon as possible and ask professionals to come to repair.

There are several reasons why Gree air conditioners do not heat:

1. The refrigerant is insufficient, because the refrigerant is insufficient due to air leakage.

2. The four-way valve is broken. The coil of the four-way valve burned out, and the nylon ball inside the four-way valve was blocked.

3. The defrosting controller fails. When the air conditioner is not transferred to the defrosting state in time, there will be frosting in the evaporator when the heat pump is heating.

First of all, check whether it is a single cooling air conditioner (only refrigeration can not heat), single cooling and heating air conditioner can be judged by whether the air conditioning model is KFR at the beginning, if KF is single cooling, KFR is cold and warm. If the air conditioner does not produce hot air for the heating and cooling machine, it is recommended to adjust the sun mode, adjust the temperature to 30 degrees, wait patiently for 5-15 minutes, and blow the warm air when the air conditioner is preheated.

First of all, see if the air conditioner is in a normal heating state? If it is and displays, the alarm light flashes and does not heat, it should be the problem of the air conditioner, then you need to find the air conditioning after-sales service personnel to repair, if it has been insured, the specific cost of charging may be higher than others, but the manufacturer's personnel maintenance is more assured.

The reason why the air conditioner does not heat up:

1. Lack of fluoride. 2. The air outlet of the internal machine is not smooth, and the filter needs to be cleaned.

3. The four-way valve is slightly drained.

4. There is a problem with the extra capillary or single valve for heating.

5. The efficiency of the compressor is reduced due to aging.

6. The outdoor temperature is low or the humidity is high, resulting in the efficiency of the air conditioner itself decreasing7. The auxiliary electric heating is not started.

For details, please call us or make an appointment for maintenance.

The reason why the Gree air conditioner is not heating warm:

1. Poor room sealing: The use environment of the air conditioner is very important, if you find that the air conditioner at home is not heating, you need to check the seal in the house. When the doors and windows are open, the indoor temperature cannot be raised, so when the user turns on the air conditioner, he must make sure that the doors and windows are closed.

2. Incorrect selection of the number of horsepower of the air conditioner: The incorrect number of horses purchased by the user will also cause the Gree air conditioner to not heat. For example, the actual area of the house is 40 square meters, but the user buys a 1 HP air conditioner, and the air conditioner needs a lot of consumption to raise the temperature.

Therefore, the right number of air conditioners is necessary to make the air conditioner effective.

3. Insufficient refrigerant: In the long-term use of Gree air conditioner, the continuous consumption of refrigerant will lead to poor heating effect of air conditioner. Due to the leakage of the refrigeration system, there is not enough refrigerant involved in the thermal cycle in the system, which reduces the heat exchange rate, resulting in insufficient heat production.

4. Failure of the defrosting controller of the air conditioner: the failure of the defrosting controller will also cause the air conditioner not to heat, for the heat pump air conditioner using the hot defrosting and defrosting device, the failure of the defrosting controller will cause the air conditioner to be unable to turn into the defrosting operation state in time, and the evaporator will frost during heat pump heating, which will affect the heat exchange efficiency of air conditioning heating and lead to insufficient heat production.

5. Too much dust accumulation of air conditioning: the cooling and heating effect of air conditioning is not good, partly because there is too much dust accumulation for the air filter, because the outdoor unit is installed outdoors, after a long time of use, it will make the radiator absorb a lot of dust and garbage and other dirt, so that the heat dissipation effect of the radiator is poor and the heating and refrigeration effect of the air conditioner is not good.

Common faults of Gree air conditioners

1. Insufficient refrigerant: self-test can be carried out to identify whether there is fluorine leakage.

2. Four-way valve string gas: Heat pump air conditioner switches the refrigeration and heating state through the four-way valve. Some of the refrigerants that should be involved in heat exchange are directly returned to the return air pipe from the compressor outlet pipe at the four-way valve, resulting in a decrease in the refrigerant involved in heat exchange, and a decrease in heat exchange efficiency, resulting in insufficient heat production.

3. Air leakage of one-way valve (also known as non-reverse service Qingye valve): the difference between high and low pressure of the refrigeration system decreases, the temperature of the outdoor heat exchanger rises, and the heat obtained from the outside world decreases, resulting in insufficient heat production. If the pressure of the system is detected, it will be found that the pressure on the low pressure side rises, and the positive difference between the high and low pressure decreases.

4. Defrosting controller failure: If the air conditioner cannot be transferred to the defrosting operation state in time, the evaporator will frost during heat pump heating, which will affect the heat exchange efficiency of air conditioner heating, resulting in insufficient heat production and even shutdown. It should be important to observe whether the defrosting temperature sensing device is misaligned, the contact is sticky or the contact is poor, the fan impeller is slippery or the air duct is blocked, and the solenoid valve or starting relay fails.
