Possible Causes

Shorted oven temperature sensor, Welded bake or broil relay on EOC, Failed high-limit thermostat, Blocked cooling airflow

How to Fix / Troubleshooting

Safety first: If the oven is overheating, turn off power immediately and allow it to cool. Do not use the oven until the issue is resolved.

  • Test sensor: Measure the oven temperature sensor resistance at room temperature. Replace if out of specification.
  • Check relays: With power off, inspect the EOC for signs of overheating around the relay area. If the oven continues to heat when turned off, a relay is likely welded closed; replace the EOC.
  • Inspect cooling system: Ensure the cooling fan runs during high-temperature operation and vents are clear.
  • High-limit thermostat: Locate and test any high-limit thermostats for continuity. Replace if open and investigate cause of trip.
