How to Fix / Troubleshooting
Safety first: Do not repeatedly reset a breaker that trips immediately; risk of fire or electric shock. Unplug the freezer before inspection.
Steps:
- Visual inspection: Check the mains cable and plug for damage or signs of overheating.
- Rear compartment: Remove the rear panel and look for burnt wires, melted insulation, or signs of arcing around the compressor, defrost heater connections, and mains filter.
- Moisture check: Inspect the defrost heater area and wiring for moisture or corrosion. Allow the unit to dry completely if there has been a spill or condensation.
- Isolate components (advanced): A technician can disconnect components (compressor, heater, fan) one by one to identify the faulty part.
- Replace faulty part: Common culprits are the defrost heater, mains filter, or compressor. Compressor or sealed-system replacement must be done by a refrigeration technician.
