How to Determine Compressor Damage?

[DeGenesis]

Methods to determine compressor damage: 1. Check if the input power circuit has electricity; 2. Inspect compressor accessories, including thermal protection and relay. Damaged thermal protection will prevent the compressor from receiving power, while a faulty relay will cause the motor not to rotate and emit a humming sound when powered on. In such cases, the machine should be stopped immediately; 3. Examine whether all connector contacts are intact and if plugs are tightly fitted without looseness; 4. Check if the circuit voltage is normal; 5. Verify if the temperature relay contacts are connected by removing the relay box cover to inspect the contacts. A compressor is a driven fluid machine that converts low-pressure gas into high-pressure gas, serving as the heart of a refrigeration system. It draws in low-temperature, low-pressure refrigerant gas through the suction pipe, compresses it via piston movement driven by the motor, and then discharges high-temperature, high-pressure refrigerant gas through the discharge pipe, providing power for the refrigeration cycle.
