How to Fix / Troubleshooting
Safety: Do not repeatedly reset a tripping breaker. Unplug the unit and investigate.
Steps:
- Inspect cord: Check the power cord for cuts or burns. Replace if damaged.
- Isolate components: With the unit unplugged, disconnect fan motors and then reconnect one at a time to identify a shorted component (requires electrical knowledge).
- Compressor test: Measure resistance to ground from each compressor terminal. Any continuity to ground indicates a shorted compressor requiring professional replacement.
- Control board: Inspect the main control board for burned traces or components. Replace if damaged.
