How to Fix / Troubleshooting
Safety: Do not repeatedly reset a tripping breaker. Unplug the freezer and investigate. Risk of electric shock is present.
- Visual inspection: Check the mains cable and plug for damage or signs of overheating.
- Isolate components (advanced): With the freezer unplugged, a technician can disconnect the compressor, defrost heater, and other loads one by one to identify which causes tripping when re-energized.
- Check for moisture: Inspect the defrost heater area and wiring for water ingress or damaged insulation.
- Professional testing: Use an insulation tester (megger) to check compressor and heater insulation resistance to earth. Low readings indicate a fault.
Important: Because of shock and fire risk, this fault should generally be handled by a qualified electrician or appliance technician.
