My Oven Fan Won't Turn Off

01 - Range/Stove/Oven Oven Control Board
The oven control board has relays that regulate power to the bake, broil and fan circuits according to the user settings and sensor input. If one of these relays shorts out, the control board may send continuous voltage to the oven fan. However, this is rarely the case. Before replacing the control board, first check the oven thermostats. If an oven thermostat fails, it may cause the oven fan to run continuously.

02 - Range/Stove/Oven Control Board
If the oven fan is not shutting off, a relay on the control board may be stuck closed sending constant power to the oven fan. Check the wiring diagram first before replacing the board. Control boards are often misdiagnosed.

03 - Normal Cooling Down Period
The oven cooling fan may run well over an hour after the oven is shut off to cool down the components. The hotter the temperature was set the longer the cooling fan needs to run to cool off the oven. This is normal.
04 - Range/Stove/Oven High Limit Thermostat
The high limit thermostat sends voltage to the oven fan as the oven heats up. If the high limit thermostat is defective, it may keep sending voltage to the oven fan after the oven has cooled down. To determine if the high limit thermostat is at fault, use a multimeter to test the thermostat for continuity. If the high limit thermostat does not have continuity, replace it.

05 - Range/Stove/Oven Thermostat
The thermostat sends voltage to the oven fan as the oven heats up. If the thermostat contacts are stuck closed, the thermostat may continue to send voltage to the oven fan after the oven has cooled down. To determine if the thermostat is at fault, use a multimeter to test the thermostat for continuity. If the thermostat shows continuity at any temperature, this indicates that the thermostat is defective. If the thermostat is defective, replace it.

06 - Range/Stove/Oven Cooling Fan
An oven cooling fan can stay on for up to 90 minutes after the oven is turned off to cool down components. This is normal.
