How to solve the problem that the air conditioner compressor is not working

1. What is the reason why the air conditioner compressor is not working? One of the more common reasons is that the air conditioner has been used for a long time, so that the freon** inside the air conditioner is insufficient, so the air conditioner compressor does not work. 2. There is also the fact that the air-conditioning compressor works under load for a long time, and the current is too large, so that the surface temperature of the air-conditioning compressor will rise, and the line card of the power supply line will be burned out after a long time, so that the air-conditioning compressor does not work.

3. You can check the power cord first, if the power cord is not in good contact or the power cord is not plugged in, it will make the air conditioner compressor not work. 4. Another reason is that during the installation of the air conditioner, the connecting pipe is bent, so that the compressor has been working under load, resulting in the air conditioning compressor not working.

1. The air-conditioning compressor does not work - the working principle of the air-conditioning compressor is introduced.

When the air conditioner is running, the compressor extracts the refrigerant from the low-pressure area and sends it to the high-pressure area for cooling and condensation after compression, and emits heat into the air through the heat sink, and the refrigerant also changes from gaseous to liquid, and the pressure increases. The refrigerant then flows from the high-pressure area to the low-pressure area, and is injected into the evaporator through the capillary, the pressure drops sharply, and the liquid refrigerant immediately becomes gaseous, absorbing a large amount of heat in the air through the heat sink. In this way, the air conditioning compressor works continuously, and constantly absorbs the heat at one end of the low-pressure area into the refrigerant, and then sends it to the high-pressure area to dissipate into the air, which plays a role in regulating the air temperature.

2. The air conditioning compressor does not work - freon is insufficient.

Reason: Air conditioning compressor not working is generally caused by the lack of freon as an air conditioning refrigerant.

Solution: Replenish the air conditioner with freon.

3. The air-conditioning compressor does not work - the installation is not standardized.

Reason: When the air conditioning system is not discharged, there will be ice blockage, which will increase the load of the compressor, and the increase of the shrinkage load will cause the compressor temperature to increase, and the refrigeration oil will deteriorate at high temperature for a long time, which will not play the role of lubrication and cooling, so as to further increase the temperature of the compressor, and the coil will be reduced due to high temperature insulation, resulting in damage to the compressor and not working.

Solution: Strictly control the quality at the time of installation.

4. The air conditioning compressor does not work - the voltage is low.

Reason: The power supply is not connected well or there is no power, the power lead socket is not in good contact, or the power lead wire diameter is thin or aging, which will lead to low power supply voltage and cause the air conditioner compressor to not work.

Solution: Check whether the circuit is normal, and install a voltage regulator.

5. The air conditioner compressor does not work - function lock protection.

Reason: Some brands or models have a lock protection function, if you are in lock mode and cannot perform any operation, you can refer to the manual to cancel; If the compressor is working at high temperature for a long time, resulting in a decrease in insulation, a low coil resistance, an increase in the starting current, and an instantaneous increase in the temperature of the compressor, the air conditioner locking protection will also be activated.

Solution: Refer to the manual to unlock or ask a professional for help.

6. The air-conditioning compressor does not work - the outdoor unit is too dirty.

Reason: The outdoor unit is too dirty, which will cause the air conditioner to dissipate heat poorly, increase the compliance of the compressor, and may damage the compressor for a long time, causing the compressor to not work.

Solution: Clean the outdoor unit.

There are many reasons why the air conditioning compressor does not work, if the air conditioning compressor at home does not work, even if you know which aspect of the problem is, it is recommended that the user find a professional to check and repair, because the air conditioning compressor is more complicated, and unnecessary accidents may occur if you repair it privately.

If the compressor of the air conditioner does not work, the first consideration is whether the power supply of the air conditioner is not plugged in properly, or there is a short circuit inside the air conditioner, which causes the compressor to not work. If there are no above two problems, then it is possible that the compressor is damaged.

1. Check whether the air conditioner is in a refrigerated state.

During maintenance, we often encounter this situation: after turning on the air conditioner, we find that the indoor unit fan is normal, but the compressor is not running. At this time, we can first observe the temperature of the outdoor unit, if the temperature of the outdoor unit is significantly higher than that of the indoor unit, it indicates that the outdoor machine has been running, at this time, it can be judged that there is a temperature difference between the internal and external units, resulting in the internal and external units can not be refrigerated at the same time.

For this kind of failure, it can be solved by adjusting the ratio of the cooling time of the internal and external mechanisms. For example, if the heating time is shorter, when the outside temperature is low, the internal machine will automatically stop heating, and when the outdoor temperature is high, it will restart, so that the internal and external circulation can be alternated. Of course, the specific time ratio needs to be based on the actual usage.

2. Check whether there is any foreign matter blocking the filter screen or evaporator.

If you find that the air outlet of the evaporator has a peculiar smell during use, and it feels hot when you touch it with your hands, then it is likely that the filter screen is blocked. In this case, it is only necessary to clean or replace the filter with a new one.

3. Check whether there are foreign substances entering the evaporator.

Sometimes, during use, we will accidentally stuff some hard objects (such as keys) and other things into the gap of the evaporator, resulting in its inability to dissipate heat, and then causing the compressor to fail to start normally. In this kind of coincidence, we only need to gently dredge with a fine needle to restore normal operation.

It may be because the freon inside the air conditioner is not rented enough, and it can be solved by adding freon; It may also be that the power supply line card of the air conditioner compressor is burned out, which can be solved by reconnecting; It may also be that the air conditioner is in a state of locking function protection, and the locking function can be unlocked according to the air conditioner's manual; It may also be that the power cord of the air conditioner is not plugged in properly, and the air conditioner does not need to be readjusted; It is also possible that the connecting pipe of the air conditioner is crooked during installation, which can be solved by reinstalling. 1. The most common thing is that the air conditioner has been used for too long, resulting in the lack of freon ** inside the air conditioner, which causes the air conditioner compressor to not work, and it is necessary to supplement the air conditioner with freon. 2. The compressor works under load for a long time, and the current is too large during operation, and the temperature on the surface of the air-conditioning compressor rises, resulting in the power supply line card being burned out, and a new line card needs to be replaced.

3. When the air conditioner is in the state of locking function protection, it will cause the air-conditioning compressor to not work, and no operation can be carried out at this time, and the locking function needs to be unlocked according to the instruction manual of the air conditioner. 4. If the power cord of the air conditioner is not plugged in well or the power cord is not in good contact, the compressor will not work, and the power cord of the air conditioner needs to be readjusted, and the voltage of the air conditioner must be stabilized. 5. In the process of installing the air conditioner, because the connecting pipe is distorted, it will lead to the increase of the working load of the compressor and cause it to not work, and the air conditioner needs to be reinstalled, and the power cord of the air conditioner should be checked whether it is aging.

There are many reasons why the aircon compressor does not work, such as the aging of the compressor. Or the compressor is running, the capacitor is aging, or the capacity is insufficient.

If the compressor is aging, it can only be replaced with a new compressor, if the starting capacitor capacity is insufficient, you can replace a new starting capacitor.

Hello, if the air conditioning compressor does not work, there may be many reasons for this existence, and it needs to be carefully checked, and the reasons for not working: First, the internal wear and tear of the compressor is serious, resulting in the inability to work normally. It is important to know that the compressor can play a vital role in the air conditioning system, and its main job is to compress and deliver cold air, which causes the compressor to be in a state of high-speed rotation for a long time.
