How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a tripping breaker. Turn off the cooker at the isolator and leave off until inspected.

  • Identify which function trips: Try turning on each oven and hob zone separately (if safe and supervised) to see which causes the trip.
  • Inspect elements: Look for visible damage or signs of arcing on elements and wiring.
  • Dry out moisture: If the trip occurred after a spill or steam cleaning, allow the appliance to dry for 24 hours with doors open before retrying.

When to call a technician: A qualified electrician or AGA engineer must perform insulation resistance tests and replace any faulty components.
