How to Fix / Troubleshooting

Safety: This is a serious electrical issue. Unplug the freezer and do not repeatedly reset the breaker.

Inspect power cord: Look for cuts, crushed sections, or burn marks. Replace the cord if damaged.
Check for moisture: Inspect the defrost heater area and wiring for signs of water ingress or corrosion. Allow the unit to dry completely if recently defrosted or flooded.
Insulation testing: A qualified technician should perform insulation resistance tests on the compressor and heater circuits to locate leakage.
Component replacement: Replace any component found to be shorted or leaking to earth (compressor, heater, wiring harness).

Test: After repairs, the unit should operate without tripping the breaker. Always use a properly rated circuit.

Freezer trips the household circuit breaker or RCD when it starts or randomly during operation.
