Possible Causes

Shorted bake or broil element, Pinched wiring harness touching chassis, Damaged terminal block, Faulty control board causing overcurrent

How to Fix / Troubleshooting

Safety First: Leave the breaker off until the fault is identified. Risk of fire or shock exists.

  • Inspect elements: With power off, visually inspect the bake and broil elements for cracks or spots where the element may contact the metal cavity.
  • Test for shorts: Disconnect element leads and measure resistance from each terminal to the oven chassis. Any low resistance indicates a shorted element that must be replaced.
  • Check wiring: Inspect the wiring harness near the elements and terminal block for melted insulation or contact with sharp edges. Repair or replace damaged wires.
  • Terminal block: Inspect the terminal block for burnt connections that could cause arcing. Replace if damaged.
  • Control board: If all hardware is good, the control board may be misfiring relays and should be evaluated and replaced if necessary.
