Possible Causes

Shorted heating element, Pinched or damaged wiring, Moisture inside electrical components, Failed power module or control board

How to Fix / Troubleshooting

Safety first: Do not repeatedly reset a breaker that trips immediately. This indicates a potentially dangerous fault. Disconnect power and leave it off until the issue is identified.

  • Identify trigger: Note which function (specific burner, bake, broil, etc.) causes the trip.
  • Inspect visible wiring: With power off, remove rear or bottom panels to inspect wiring to the affected component for burns, melted insulation, or pinched wires.
  • Check elements: For electric ovens and cooktops, inspect elements for cracks or contact with metal chassis.

Replace any damaged wiring or shorted elements. If no obvious damage is found, the fault may be inside a sealed module or control board and should be diagnosed by a technician.
