What s the matter if the Gree air conditioner is not hot

Gree air conditioner. What is the reason for not heating?

1. The length of the copper pipe is unreasonable.

According to the principle of air conditioning refrigeration.

Introduction, whether the length of the copper pipe connected between the outdoor unit of the air conditioner and the indoor unit is reasonable, or whether the production degree is shortened as much as possible will also help the refrigeration effect of the air conditioner, and the air conditioner of some owners is not very reasonable because of the needs of the installation at that time, so that the ventilation pipe is too long, so that the low heat transfer efficiency will also cause the air conditioner not to refrigerate.

Ad. 2. The air conditioner is not cleaned for a long time.

If you want the air conditioner to operate normally and not affect human health, but also to prolong the life as much as possible, obviously, it is impossible to leave it alone as soon as you buy it and install it. Because the outdoor unit is exposed to the outdoors, it is easy to absorb dust and debris, and if it is not cleaned for a long time, it will affect the heat dissipation performance of the machine, resulting in the reduction of the cooling effect of the air conditioner. The indoor unit is related to the health of the human body, and if it is not cleaned for a long time, it will breed bacteria, pollute the air, and make people sick.

3. The external ambient temperature is too high.

This kind of non-refrigeration situation is common in our outdoor unit installed in a relatively closed space or the temperature around the outdoor unit is too high, so it is extremely easy to cause the heat emitted by the radiator to flow away due to the lack of air circulation in the small space where the outdoor unit is located, so that the air conditioner is not refrigerated; There is also a common saying that when the outdoor temperature exceeds 43 degrees, most air conditioners are difficult to transfer indoor heat to the outside through the radiator of the outdoor unit, which will also cause the air conditioner to not refrigerate.

What should I do if the Gree air conditioner does not heat?

1. First of all, we must check whether the mode of the basic setting of the air conditioner is correct when we use the air conditioner in daily life, some people set the mode incorrectly, of course, the machine will not work normally. We should also pay attention to the temperature of the air conditioner, it is recommended to set it at 28 degrees to 30 degrees. The room should be closed and not ventilated.

In short, the heating of the air conditioner is to take the temperature from the outside, and the outdoor temperature is too low, the worse the heating effect of the air conditioner. Therefore, the outdoor temperature is also the reason that determines whether the Gree air conditioner in your home can be heated.

2. Gree air conditioner does not heat or the effect is not good, it also depends on whether the number of machines bought is in line with the room area, the room is too large to affect the effect, the heat can not go up, the air conditioner itself is heating normally, but if you do not turn on the auxiliary electric heating, there is also a part of the heating less. The filter screen of the air conditioner should also be cleaned frequently, if there is too much dust attached, then it will cause insufficient circulating air. Blow out hot air.

It is not enough, and there is also a lack of fluorine, which will also lead to insufficient heating of Gree air conditioners.

After reading the above text, people must have known the reason why Gree air conditioner does not heat? What should I do if the Gree air conditioner does not heat? People need to know more about the small problems that Gree air conditioning water is prone to in life, so that it will be more convenient to solve them by themselves.

There are many reasons why the air conditioner is not hot, generally the air conditioning power is not enough, and the heating effect of the large room with the small power air conditioner will be very poor. If the indoor unit filter is too dirty, it will also affect the air conditioner, so it is recommended to remove the filter and clean it.

There is hot air after the water temperature comes up, and in winter, you don't need to press the AC switch, waste of oil, you drive for 5 minutes, and there will be hot air after the water temperature comes up.

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

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:

The mold ant section first checks the cause of the lack of fluoride in the air conditioner, and then repairs and adds fluoride. If the fluoride is consumed during normal air conditioning work, only the air conditioner needs to be fluoridated; If it is a lack of fluoride caused by air conditioner leakage, it is necessary to detect leaks, fill leaks, and add fluoride to test the machine.

2. The air conditioner is too dirty, resulting in pipeline blockage. The phenomenon of dirty blockage in the empty nuclear disturbance 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:

Regularly clean the air conditioner, especially the filter in the air conditioner, 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 high pressure of the air conditioning power supply is insufficient, it is likely to cause the air compressor or other components to work less efficiently, which will lead to poor thermal capacity of the refrigeration and belt ruler. Here's how to repair it:

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

4. The four-way valve of the air conditioner is faulty. The relationship between the air conditioner and the four-way valve is very important. If there is a failure of the four-way limb valve of the air conditioner, 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.

The maintenance method is as follows: 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 heating of the air conditioner will not be able to detect the normal temperature, which will cause the air conditioner to be unable to heat normally. Here's how to repair it:

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

Gree air conditioner does not produce hot air reasons:

1. Look at the model of the air conditioner, KF is a single cooling air conditioner, which has no heating function, and KFR starts with a cold and warm air conditioner, which can make heat.

2. It is a heating and cooling air conditioner but cannot be heated, first check whether the mode setting is not set correctly, and it must be adjusted to the heating mode to produce hot air.

3. The air conditioner does not clean the filter screen in time after long-term use and the air circulation is blocked, which will affect the heating effect of the air conditioner to a certain extent, and the dust and scale of the evaporator and condenser are too thick, which will also reduce the heat exchange effect, resulting in a decrease in heating capacity and an increase in power consumption.

4. The four-way valve will also cause the air conditioner not to heat, and the heat pump type air conditioner switches the refrigeration and heating state through the four-way valve, and some of the refrigerants that should be involved in heat exchange are directly returned to the return pipe from the compressor outlet pipe at the four-way valve, resulting in the reduction of refrigerant participating in heat exchange, and the decrease of heat exchange efficiency, thus causing insufficient heating production.

5. The failure of the defrosting controller will also cause the air conditioner to not heat, so that the air conditioner cannot be transferred to the defrosting operation state in time, and the evaporator will frost during heat pump heating, resulting in insufficient heating and even shutdown.

This phenomenon can be caused by the large size of the room, the insufficient number of air conditioners, and the excessive dust accumulation of air conditioners.

Reasons why hot air is not hot:

1.It is recommended to replace the air conditioner with a larger power, or add another air conditioner, which can also improve the indoor thermal insulation or reduce the indoor area, such as paying attention to closing doors and windows, using partitions to reduce the area of the air conditioner, etc.

2.Too much dust accumulation on the air conditioner filter and pipes: After the air conditioner is used for a long time, there will be a lot of dust on the filter screen and the pipes of the air conditioner, which will block the air outlet, resulting in a decrease in air volume and a decrease in the heating effect, so the air conditioner needs to be cleaned regularly, some air conditioners have a cleaning function, and the system will automatically clean the air conditioner when the clean button is pressed.

3.Outside temperature too low: If the outside temperature is too low, the air conditioner will not work properly.

If the outdoor temperature is too low for the outdoor air conditioner to normalize the defrosting, then the air conditioner will not be able to heat up. If the outside temperature is very low, it is not recommended to use air conditioners as heating tools, and it is recommended to use radiators and floor heating facilities such as North Stuffy Chain Stool.

4.The voltage at home is too low: If the voltage at home is relatively low, the air conditioner can not work normally in a low-voltage environment, which will lead to a decrease in the heating effect, it is recommended to use the air conditioner after installing a voltage regulator.

Solution:1Remove accumulated dust:

The air conditioner needs to be cleaned regularly, and the dust accumulated in the air conditioner can be removed in time to better extend the service life of the air conditioner and its cooling and heating effect. If the Gree air conditioner does not heat up due to the dust accumulation on the filter, the user only needs to remove the dirt in the air conditioner in time.

2.Adjust the set temperature: The air conditioner sets the temperature differently in summer and winter, so when setting the temperature in winter, it cannot be set according to the way the temperature is set in summer, so the user only needs to adjust the temperature set by the air conditioner to restore the heating effect of the air conditioner.

3.Replace the number of air conditioners: when the user finds that the power of the air conditioner purchased is too small to match the size of the room, in the case of being able to replace the product, the user can replace the new high-power air conditioner, if it cannot be replaced, the user can also achieve the insulation of the indoor temperature by thickening the doors and windows.

4.Check the power supply voltage: When using the air conditioner, users can choose to avoid peak power consumption periods, or prepare a voltage regulator at home and use the voltage regulator to stabilize the power supply voltage and let the air conditioner work at the normal voltage.

5.Increase the refrigerant of the air conditioner: When the refrigerant of the air conditioner leaks or runs out, the user needs to re-weld the leaked part of the refrigerant, and then ask professionals to add the air conditioning refrigerant to ensure the normal operation of the air conditioner.

6.Check the air conditioner frost controller: When the air conditioner frost controller fails, the user needs to check whether the frost defrosting temperature sensor is misaligned, the contact is poor, or the wind calls the early road blockage, etc., and then eliminate the fault one by one.

There are many reasons why there is no hot air:

1. Check whether the function settings of the remote control are wrong and correct them.

2. When the air conditioner is running, check whether the indoor fan is running. The absence of blowing at the start of heating is a temporary phenomenon. If it does not blow for a long time, it is the fault of the internal fan; If it is cold air, check whether the outdoor unit has been put into operation, if there is operation, it is suspected that it is caused by fluorine leakage or four-way valve heating.

3. The failure of the external machine is caused by its own failure or the failure of the control circuit components. It is recommended to find after-sales service, eliminate electrical faults or leaks, and add fluoride.

The reasons why the air conditioner does not produce hot air are as follows:

1. The filter screen of the air inlet of the air conditioner is not clean enough;

2. The external compressor lacks freon or has a place where fluorine leaks;

3. There is dirt on the aluminum sheet of the air conditioner, which is the deterioration of the heating effect;

4. The evaporation place of the internal machine is blocked.

The solution to the poor heating effect of the air conditioner is as follows:

1. Remove the filter screen of the air inlet of the air conditioner and clean the virtual oak bush;

2. Repair the fluorine leakage of the compressor of the air conditioner;

3. Wipe off the dirt on the aluminum sheet of the air conditioner;

4. Unblock the evaporation blockage of the internal machine.
