Freezer trips the household circuit breaker or RCD when it starts or after running for a while.

Safety: This symptom indicates a potential shock or fire hazard. Unplug the freezer and do not repeatedly reset the breaker.

Steps:

• 1. Inspect power cord: Look for cuts, crushed sections, or burn marks. Replace if damaged.
• 2. Check rear compartment: Remove the rear panel and look for signs of water, corrosion, or burnt components.
• 3. Defrost heater check: Disconnect the defrost heater and try powering the unit (only if you are competent and safe to do so). If the breaker no longer trips, the heater is likely shorted and must be replaced.
• 4. Compressor test: A compressor shorted to ground will trip breakers. Testing requires a multimeter and should be done by a technician.

Recommendation: Due to the risk involved, contact a qualified service technician for further diagnosis and repair.
