What is the reason why the refrigerator compressor does not work What are the performances of the refrigerator compressor broken Refrigerator The compressor is the heart of the refrigerator and the core component of the refrigerator. If the refrigerator compressor does not work, the entire refrigerator will not run. So why is the refrigerator compressor not working in daily use? What are the symptoms if the refrigerator compressor is broken? Next, I will introduce you to the reason why the refrigerator compressor does not work and the symptoms of the refrigerator compressor broken. 1. What is the reason why the refrigerator compressor does not work 1. The ambient temperature is too low When the ambient temperature is too low (1~10℃), if the refrigerator is manually compensated, when the ambient temperature is lower than 0℃, the compressor oil will become thick and the lubrication performance will be poor; meanwhile, the condensing pressure will be low and the refrigerant will not flow in If the evaporator continues to use the refrigerator, the compressor will be damaged. 2. Failure of the PTC starter Another reason why the refrigerator compressor does not work is the failure of the PTC starter. You can use a multimeter ohm file to measure whether the resistance of the PTC starter's running jack and the start jack is normal. If it is infinite or 0, the PTC starter is damaged. 3. Overload protector failure You can use the ammeter compressor to start and whether the operating current is normal. If the overload protector operates normally, the overload protector will fail, which will also cause the refrigerator compressor to not work. 4. Internal fault of the compressor If the refrigerator compressor does not work, if the test compressor accessories are normal, and the compressor still cannot start, it may be a compressor internal fault. Second, the refrigerator compressor is broken 1. After the refrigerator is energized, there will be a "gurgle" sound. This phenomenon is that the hanging spring in the compressor breaks and the movement collides with the casing. At this time, the compressor vibrates strongly and must be repaired by the maintenance department. 2. If the compressor hears a "hiss" sound during operation after the power is turned on, the sound is that the internal high-pressure output buffer tube of the compressor is broken, and the high-pressure gas is discharged. 3. The sound of "buzzing" and the sound of "tapping" starting contact jump at the same time, this sound indicates that the compressor is overloaded, and the starting contact cannot be attracted due to the excessively low voltage of the power supply system. Increase. 4.Looking at the temperature of the refrigerator, you can touch the temperature of the refrigerator compressor after the refrigerator has been powered on for a period of time. If the temperature of the refrigerator compressor is very high, it means that the refrigerator compressor and other mechanical parts have failed. 3. Working principle of refrigerator compressor 1. The refrigerator compressor sucks the low-temperature and low-pressure refrigerant from the evaporator. During operation, the operation of the motor drives the operation of the piston to compress the refrigerant. After obtaining the high-temperature and high-pressure gas, the refrigerant is sent to the refrigerator through the delivery pipe to condense. In the compressor, this provides sufficient power for the refrigeration system cycle of the refrigerator, and eventually forms a gas that turns the refrigerant from the compressor into a high temperature and high pressure. 2. After passing through the condenser, it turns into a high-pressure and low-temperature liquid, which passes through the capillaries and becomes a low-temperature and low-pressure liquid that undergoes resistance, boils and vaporizes in the equal-pressure evaporator, and absorbs heat from the surrounding medium to become saturated low-temperature and low-pressure steam. . 3.Finally absorbed by the compressor again, completing the cycle of the entire refrigeration system. The above is about the reason why the refrigerator compressor does not work, and the refrigerator compressor is broken. I hope it can help everyone
