Possible Causes
Failed compressor, Defective start relay or capacitor, Open thermal overload, Loose compressor wiring
How to Fix / Troubleshooting
Safety first: Unplug the unit before accessing the compressor compartment.
- Check wiring: Inspect the wires and connectors on the compressor terminals for looseness or burns. Reseat or replace as needed.
- Inspect start device: Remove the start relay/overload assembly and check for rattling pieces or burn marks. Replace if damaged.
- Test for continuity (advanced): With a multimeter, check the compressor windings for continuity and appropriate resistance values.
- Allow cooling: If the compressor is very hot, let it cool for 30–60 minutes and try again; the overload may have tripped.
If the compressor windings are open or shorted, or if it hums and trips repeatedly, the compressor is likely failed and requires professional replacement.
