Possible Causes

Welded bake or grill relay on EOC, Shorted triac driving element, Faulty oven temperature sensor reading low, Control board logic failure

How to Fix / Troubleshooting

Safety first: If the oven is overheating, switch off power at the mains immediately. Do not open the door until temperatures have dropped to avoid a blast of hot air.

  • Test sensor: After cooling and disconnecting power, check the oven sensor resistance at room temperature. Replace if out of specification.
  • Check element operation: With power restored, observe whether elements heat even when the oven is off. If so, disconnect power and inspect the EOC for welded relays or shorted components.
  • Replace EOC: If a relay is stuck closed or the board shows heat damage, replace the EOC. Transfer each wire one at a time to avoid miswiring.

Do not continue using the oven with a known runaway temperature condition; this is a serious fire hazard.
