Haier refrigerator, Beijing Samsung refrigerator repair phone number, comprehensive analysis of compressor fault repair
Fault phenomenon: Compressor malfunction.
Analysis and maintenance: Compressor faults can be divided into mechanical faults and electrical faults.
(1) The main faults of the mechanical part are:
①The suction and exhaust valve plates of the compressor are broken or deformed, and the gasket of the high and low pressure gas chamber is damaged, causing internal leakage of the compressor. The operating current of the compressor is lower than the rated value. Although it can run, it does not refrigerate;
②The high-pressure exhaust buffer pipe of the compressor is broken, which makes its noise significantly increased when running, and the operating current of the compressor is lower than the rated value;
③ The anti-vibration spring of the compressor is detached or broken from the casing, making the compressor produce metallic knocking and vibration noise in the shell when starting and stopping.
(2) The main reason for the fault of the electrical part of the compressor is: the motor winding is burned (most of them are start winding burnout, and the operation winding is only possible to be burned when the refrigeration system is ice blocked or dirty blocked). As a whole, the disassembly and assembly of the compressor are relatively troublesome, so accurately judging the fault of the compressor is the key to repairing the electrical part in the Beijing Samsung refrigerator repair center.
