How to Fix / Troubleshooting
Do not repeatedly reset the breaker without finding the cause. Unplug the cooler before inspection.
- 1. Inspect power cord:
- Check the power cord for cuts, burns, or crushed sections; replace if damaged.
- 2. Check compressor and relay:
- Remove the compressor start relay and overload; inspect for melting or charring.
- 3. Inspect control board:
- Look for signs of arcing or burn marks on the main control board.
- 4. Dry moisture:
- If water has dripped onto electronics, allow everything to dry completely and correct the source of the leak.
- 5. Replace shorted components:
- Install new OEM parts for any shorted relay, board, or wiring.
- 6. If breaker still trips:
- The compressor may be internally shorted; this requires a licensed refrigeration technician.
