How to Fix / Troubleshooting
Critical safety warning: Repeated breaker tripping indicates a serious electrical issue. Do not keep resetting the breaker without inspection.
- 1. Verify circuit rating: Check the unit's nameplate amperage and ensure the circuit breaker and wiring are appropriately sized.
- 2. Inspect cord and plug: Look for damage or burn marks. Replace if any defects are found.
- 3. Isolate cause (advanced): With the unit unplugged and covers removed, visually inspect for burnt components or wiring. A technician can disconnect the compressor and test if the fan alone runs without tripping, then test compressor separately.
- 4. Professional repair: Shorted motors or compressors must be replaced by a qualified technician.
