How to Fix / Troubleshooting
Safety: Unplug the appliance before testing compressor components. Only qualified persons should test live circuits.
Steps:
- Check compressor temperature: If the compressor is cold and silent while the fan runs, it is not starting.
- Test start relay and overload: Remove and test these components with a multimeter. Replace if open or out of spec.
- Measure compressor windings: Check resistance between compressor terminals. An open winding indicates a failed compressor.
- Inspect control board: If the compressor and start components are good, the PCB may not be energizing the compressor relay and may need replacement.
Action: Compressor or PCB replacement should be performed by a professional technician.
