Kenmore Oven fan won't turn off

When your Kenmore oven fan won't turn off, first allow the oven to cool completely. The cooling fan may run for more than an hour after the oven is switched off, especially after high-temperature cooking, and this can be normal. If the oven fan keeps running after the oven has cooled, a thermostat may be sending continuous voltage to the fan circuit, so check the oven thermostat and high-limit thermostat before replacing a control board. A stuck relay on the oven control board can also keep the fan powered, although this is less common and the board is often misdiagnosed. The main control board can cause the same problem if one of its fan relays shorts closed. Use the wiring diagram and a multimeter to test the thermostat and high-limit thermostat for proper continuity, and inspect the fan circuit wiring before ordering parts. If testing confirms a failed board, thermostat, or high-limit thermostat, replace the defective component. This guidance applies to a Kenmore oven fan that keeps running, an oven fan that won't turn off, or an oven cooling fan that continues after cooking. Enter your model number to find the exact replacement part for your Kenmore range, stove, or oven.

01 - Kenmore 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 - Kenmore 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.
Common

03 - Kenmore Range/Stove/Oven Main Control Board

The main control board has relays that send voltage to the fan motor. If one of the control board relays shorts closed, the control board may send continuous voltage to the fan. If the fan continues to run after the oven is turned off and cooled down, the main control board is likely defective. If the control board is defective, replace it.

04 - 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.
Less Common

05 - Kenmore 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.
Less Common

06 - Kenmore 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.
