Stoves Cooling fan relay stuck or sensor misreading temperature

Oven fan runs continuously even when the oven is off and cool.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Stuck cooling fan relay on control board, Shorted fan wiring, Faulty temperature sensor near control area, Control board logic fault

Safety first: Turn off power before accessing the control area.

Allow full cool-down: Ensure the oven is completely cool; some fans run until a safe temperature is reached.
Inspect control board: Remove the control panel and inspect the board for stuck or burnt fan relay. Replace the control board if the relay is welded closed.
Check fan wiring: Look for shorts that could be feeding the fan directly. Repair as needed.
Sensor check: If a separate sensor controls the fan, test it according to the service manual and replace if misreading.
