Unit trips the household circuit breaker or RCD when plugged in or shortly after starting.

Safety: Do not repeatedly reset a tripping breaker. Unplug the appliance and do not operate until the fault is found. If you are not experienced with electrical testing, contact a qualified technician.

• Inspect power cord: Look for cuts, burns, or crushed sections. Replace the Grundig power cord if damaged.
• Check for moisture: Examine the main PCB and wiring for signs of water ingress. Dry thoroughly and correct any source of leaks.
• Test components to ground: With a multimeter, check resistance between each major component (compressor, heaters) and earth. A low resistance indicates a ground fault.
• Isolate suspect component: Disconnect suspected components one at a time and test operation to identify which causes the trip.
• Replace faulty component: Install a new compressor, defrost heater, or door frame heater as required. Sealed system work must be done by a professional.
