Possible Causes
Failed compressor start relay, Open compressor overload, Faulty main control board compressor output, Broken wire to compressor
How to Fix / Troubleshooting
Safety: Unplug the unit before touching compressor wiring. High voltage is present when powered.
Steps:
- Confirm symptom: Listen and feel: the interior fan runs, but the compressor is silent and cool to the touch after 15–20 minutes.
- Inspect start device: Remove the start relay/overload from the compressor and check for burn marks or rattling. Replace if suspect.
- Check wiring: Verify that wires from the control board to the compressor and start device are intact and firmly connected.
- Control board: If a new start device does not restore compressor operation, the main control board may not be sending power to the compressor and should be replaced.
- Professional diagnosis: If the compressor still does not run with a known-good board and start device, the compressor itself is likely failed and requires sealed system service.
