Possible Causes
Stuck or burned compressor relay on main board, Faulty current sensor on PCB, Loose compressor wiring connector
How to Fix / Troubleshooting
Safety: Unplug the unit before accessing the control board or compressor wiring.
Steps:
- Listen for relay: When the unit tries to start, you may hear rapid clicking from the control board if the relay is failing.
- Inspect wiring: Remove the rear panel and check the wiring harness from the control board to the compressor. Ensure all spade connectors are tight and not burnt.
- Control board check: Examine the main PCB for burnt relay contacts or discoloration around the compressor relay.
- Replace control board: If the relay is visibly damaged or F2 persists, replace the main control board with an Insignia-compatible part.
Note: Diagnosing current-sense circuits requires specialized tools; if in doubt, have a technician confirm before replacing expensive parts.
