Possible Causes
Shorted compressor windings, Faulty start relay/PTC, Damaged power cord, Internal short on main control board
How to Fix / Troubleshooting
Critical safety: Repeated tripping indicates a serious fault. Unplug the freezer and do not reset the breaker repeatedly.
Steps (for qualified persons):
- 1. Inspect power cord: Look for visible damage. Replace if any defects are found.
- 2. Check compressor and start device: Access the compressor area and inspect the start relay/PTC for burning. Test compressor winding resistance; very low resistance or continuity to ground indicates a shorted compressor.
- 3. Inspect control board: Look for burnt components or tracks. Replace the board if damaged.
Recommendation: Due to shock and fire risk, have a professional diagnose and repair breaker-tripping faults.
