Air fryer trips the household circuit breaker or RCD when plugged in or when heating starts.

Safety first: Do not repeatedly reset a breaker that trips. Unplug the fryer and leave it unplugged until the fault is found.

Steps:

• 1. Visual inspection: Check the power cord for cuts or crushed sections. Replace the cord if damaged.
• 2. Dry moisture: If the fryer was recently washed or exposed to steam, allow it to dry for at least 24 hours in a warm, dry place before further testing.
• 3. Inspect internal wiring: Open the housing and look for wires touching the metal chassis, melted insulation, or loose strands at terminals. Repair or replace damaged wiring and secure with clips or ties.
• 4. Check heating element: Inspect the heater for cracks or contact with the metal frame. A grounded element can trip RCDs. Replace the heating element assembly if damaged.
• 5. Examine control board: Look for burned components or carbon tracking on the PCB. Replace the control board if a short is evident.
• 6. Test carefully: After repairs, test the fryer on a protected circuit. If the breaker still trips, discontinue use and consult a professional.

Warning: Ground faults are serious safety hazards; do not operate the fryer until fully resolved.
