How to Fix / Troubleshooting
Safety: Do not repeatedly reset a breaker that trips immediately; this indicates a potentially dangerous fault. Unplug the unit before inspection.
Steps to diagnose breaker trips:
- Inspect cord and plug: Look for damage or burn marks. Replace the power cord if any defects are found.
- Isolate components: With the unit unplugged, disconnect the compressor and fan motor connectors from the main board. Plug the unit in and turn it on. If the breaker no longer trips, reconnect components one at a time to identify the faulty one.
- Motor/compressor test: Measure resistance to ground from motor and compressor terminals. Any continuity to ground indicates a short and the component must be replaced.
- Board inspection: If motors and compressor test good, inspect the main PCB for burnt traces or components. Replace the main control board if damaged.
- Professional help: If you are not comfortable with electrical testing, contact a qualified technician.
