Possible Causes

Relay stuck closed on control board, Shorted cooling fan thermostat, Misreading oven temperature sensor, Wiring short

How to Fix / Troubleshooting

Safety first: Disconnect power before accessing internal components.

  • Allow full cool-down: Ensure the oven has been off for several hours. Some models keep the fan running until the control senses a safe temperature.
  • Check sensor: Test the oven temperature sensor resistance at room temperature. Replace the oven temperature sensor if out of spec.
  • Inspect fan thermostat: Some Summit ranges use a separate cooling fan thermostat. Test it for continuity at room temperature; it should be open. Replace the cooling fan thermostat if stuck closed.
  • Control board: If sensors and thermostats are good, the fan relay on the control board may be welded closed. Replace the electronic oven control board.
