Oven trips the circuit breaker or blows a fuse when turned on or when a specific function is selected.

Safety first: Do not repeatedly reset a tripping breaker. Turn off power and investigate the cause. Working on live circuits is dangerous; if unsure, contact a qualified technician.

Step-by-step checks:

• Identify when it trips: Note whether the breaker trips immediately when the oven is turned on, or only when bake, broil, or convection is selected.
• Inspect elements: Look for visible damage where elements may have warped and touch the oven cavity.
• Check wiring: With power off, inspect wiring harnesses for cuts, melted insulation, or contact with sharp metal edges.
• Test components: Disconnect suspected components (elements, motors) and test for continuity to ground (chassis). Any low resistance to ground indicates a short.

When to replace parts: Replace any shorted heating element or fan motor. Repair or replace damaged wiring. If no component is shorted but the breaker still trips, the control board may be defective.
