How to Fix / Troubleshooting
Safety First: Do not repeatedly reset a tripping breaker. Disconnect power and investigate before restoring.
- Inspect wiring: Look for burned, pinched, or bare wires touching the cabinet. Repair or replace damaged wiring.
- Isolate components: With a technician’s help, disconnect loads (compressor, fan) one at a time to identify which causes the trip.
- Check breaker and circuit: Ensure the breaker size matches the unit’s nameplate and that the circuit is dedicated.
When to call a technician: A shorted compressor or fan motor requires professional replacement and possibly sealed system work.
