We all know that air conditioners are one of our commonly used home appliances. Although many parts of the air conditioner have great effects during the working process, the compressor is the heart of the air conditioner. Once the compressor fails to work, the air conditioner will not work. work. When the air conditioner compressor is faulty, it needs to be repaired. So what are the reasons and methods for the repair of household air conditioner compressors? Next, please see the specific introduction below.

Air conditioner compressor FAQ:

1. There are many reasons for the abnormal noise of the air conditioner compressor during operation, such as damage to the electromagnetic clutch of the compressor or severe wear and tear inside the compressor.

2. Refrigerant leakage: Refrigerant leakage is one of the most common problems in air conditioning refrigeration systems.

3. The compressor does not work: There are many reasons why the compressor does not work, most of which are caused by circuit faults. One of the most common reasons is that the compressor capacitor is damaged.

There are many reasons why the air conditioner compressor cannot work. Let's take a look at the reasons why the home air conditioner compressor cannot work, as follows:

1. Lack of refrigerant: The air conditioner is prone to lack of refrigerant after long-term use. If the air conditioner is lack of refrigerant, the compressor will appear idling during operation, and it is easy to cause compressor damage in severe cases. When repairing household air conditioner compressors, we need to add refrigerant to the air conditioner in time to ensure that the compressor can operate normally.

2. The compressor power supply line card is burned: During the operation of the air conditioner, if its compressor has been working under load, the working current will be too large and the surface temperature of the compressor will rise. The power supply line card of the machine is also very easy to be blown in a high temperature environment. In the repair process, we need to replace the power supply card of the air conditioner compressor from scratch. At this time, we need to use sandpaper to clean the surface of the compressor's terminal. The rust spots are cleaned to prevent the power supply card from being blown again.

3. During the installation of the air conditioner, the joint of the indoor and outdoor unit is bent, which will increase the load of the compressor during the working process. After a long time, the air conditioner compressor will not be able to work normally. When repairing the compressor of the household air conditioner, we need to re-straighten the connection between the inner and outer units, which will reduce the workload of the compressor, and at the same time, we can also check whether the power supply of the air conditioner is present. ageing condition.

How to repair the air conditioner compressor:

1. When repairing the household air conditioner compressor, if the air conditioner compressor is lubricated and it still cannot work, then we can use the pressure relief method to repair the compressor. When the resistance value of the winding of the compressor is measured, its resistance value is normal. At this time, we can release the refrigerant from the low-pressure gas receiver of the outdoor unit of the air conditioner, and then use the water hammer to re-compress the compressor while turning it on. The lower part of the machine allows the compressor to work swiftly. At this time, we can inhale 200 ml of refrigerated oil from the low-pressure gas of the compressor where fluorine is added. After the compressor operates normally, re-install its low-pressure gas valve and low-pressure liquid valve, and finally pass the repression. , leak testing, pumping, and fluoridation for final treatment, then the air conditioner compressor will return to normal at this time.

2, start the capacitor. When repairing a household air conditioner compressor, first measure whether its power supply is normal, then open the casing of the outdoor unit, measure the starting capacitor of the air conditioner compressor, the charge and discharge are good, and then measure the three connection terminals of the compressor, the main winding M plus The resistance value of the secondary winding S should be equal to the resistance value C of the common terminal. If the wooden hammer knocking technique is used and the strong lifting method does not work, then finally an enlarged capacitor should be used to start, but the compressor should not operate for too long after starting. , Because once the starting capacitor of the air conditioner compressor is increased, the compressor will overheat.
