How to Fix / Troubleshooting
Safety: Do not repeatedly reset a breaker that trips immediately. Risk of fire or shock.
- Inspect cord and plug: Look for damage, burns, or melted areas. Replace the cord if any damage is found.
- Dry the unit: If the unit has been exposed to water, allow it to dry completely for at least 24 hours in a warm, dry area.
- Try a different outlet: Plug into a different properly grounded circuit (not a power strip) to rule out a weak breaker.
- Internal inspection (advanced): With the unit unplugged, inspect internal wiring for burns or shorts. Test compressor and fan motor windings for shorts to ground. Replace any shorted component.
