Possible Causes

Element insulation breakdown to chassis, Pinched or damaged wiring, Moisture in elements or wiring, Faulty filter or suppression capacitor

How to Fix / Troubleshooting

Safety: Do not repeatedly reset a tripping breaker. Disconnect the oven and investigate.

  • Isolate modes: Try different heating modes (bake, grill, convection) to see if tripping occurs only with a specific element. This helps identify the faulty circuit.
  • Visual inspection: With power OFF, inspect all visible wiring and elements for signs of arcing, burn marks, or contact with metal parts.
  • Insulation test (advanced): Use a megohmmeter to test insulation resistance between each element terminal and chassis. Low resistance indicates leakage and the element should be replaced.
  • Drying: If the oven was recently cleaned with water or steam, allow it to dry thoroughly for 24 hours and test again.

Important: Persistent breaker tripping indicates a safety issue. If you are not equipped to perform insulation tests, contact a qualified electrician or appliance technician.
