How to Fix / Troubleshooting
Safety: Unplug the unit before testing continuity or removing components.
- 1. Listen for relay click: When the unit calls for cooling, you should hear a relay click. If not, suspect the control board.
- 2. Check wiring: Inspect harnesses from the control board to the compressor and fans for loose or burnt connectors.
- 3. Test start relay and overload: Remove from compressor and check for continuity. Replace if open or heat-damaged.
- 4. Bypass test (advanced): A technician may temporarily bypass the control relay to test compressor operation. This should only be done by a qualified person.
- 5. Replace main control board: If wiring and start components are good, replace the control board.
