Safety first: Do not repeatedly reset a breaker that trips immediately; this indicates a potentially dangerous fault.

Step 1 – Identify when it trips: Note whether the breaker trips immediately when the oven is turned on, or only when a specific function (bake, broil, self-clean) is used.
Step 2 – Inspect elements: With power off, inspect bake and broil elements for cracks or areas where the metal sheath may be touching the oven cavity.
Step 3 – Check wiring: Remove the rear panel and inspect all wiring for cuts, pinches, or melted insulation, especially where the oven passes through the cabinet.
Step 4 – Terminal block and cord: Inspect the power terminal block for loose or burnt connections. Repair or replace as needed.
Step 5 – Professional testing: If no obvious damage is found, a technician should perform insulation resistance tests and verify the circuit breaker and wiring are correctly sized.

Warning: Electrical shorts can cause fire; do not use the oven until the cause is corrected.
