Possible Causes
Seized compressor, Failed start capacitor or relay, Low refrigerant causing abnormal operation, Internal compressor mechanical wear
How to Fix / Troubleshooting
Safety: Unplug the unit. Compressor work involves mains voltage and refrigerant; advanced repairs require a qualified technician.
Steps:
- 1. Check for overheating: After brief operation, carefully feel near the compressor shell (do not touch bare terminals). Excessive heat and loud humming may indicate a locked rotor.
- 2. Start components: Test the compressor start capacitor and relay/PTC device. Replace if out of specification.
- 3. Winding test: With power off and wires removed, measure compressor winding resistances. Open or shorted windings indicate a failed compressor.
- 4. Professional diagnosis: If start components are good but the compressor still hums and trips, a refrigeration technician should evaluate for mechanical failure or low refrigerant.
