How to Fix / Troubleshooting
Safety: This is a serious electrical issue. Unplug the freezer and do not repeatedly reset the breaker. Only proceed if you are competent with electrical testing; otherwise call a professional.
Steps:
- 1. Visual inspection: Check the power cord and plug for damage or burn marks. Replace if damaged.
- 2. Rear compartment: Inspect wiring around the compressor and defrost heater for signs of chafing or burning.
- 3. Insulation test: Using appropriate test equipment, check for earth leakage from compressor and heater. Replace any component with insulation failure.
- 4. PCB: If no external shorts are found, the PCB may be leaking to earth and should be replaced.
Recommendation: Due to shock and fire risk, involve a qualified appliance electrician or refrigeration engineer.
