Wine cooler trips the household circuit breaker or RCD when it starts.

Safety: This symptom indicates a potentially dangerous electrical fault. Unplug the unit immediately and do not repeatedly reset the breaker.

Steps to diagnose (for qualified persons):

• Inspect cord and plug: Look for visible damage or burn marks. Replace if damaged.
• Check for moisture: Inspect the rear compartment and control area for signs of water ingress. Dry thoroughly and correct any leaks.
• Isolate components: With the unit unplugged, test compressor, fan motors, and heater circuits for shorts to ground using a megohmmeter.
• Professional service: If any component is shorted, it must be replaced by a qualified technician. Sealed system or main board faults should be handled by an authorized Fisher & Paykel service provider.
