How to Fix / Troubleshooting
Safety: Do not repeatedly reset a breaker that trips immediately. Unplug the unit and keep it disconnected until the fault is found.
Steps:
- Inspect for moisture: Check inside the unit for signs of water leaks onto wiring or the control board. Dry thoroughly and fix any leaks.
- Check power cord: Replace the cord if there is any visible damage.
- Component isolation: A technician can disconnect components (compressor, fan, pump) one at a time and test to identify which is shorted.
Warning: Because this involves potential shock and fire hazards, professional diagnosis is strongly recommended.
