RCA Oven fan won't turn off

Won’t your RCA oven fan turn off? The cooling fan may be receiving continuous power from a stuck relay in the oven control board or main control board. Before replacing either board, check the wiring diagram and test the oven thermostats, since a failed thermostat can also keep the fan running. The high-limit thermostat may continue sending voltage after the oven cools, while a thermostat with contacts stuck closed can produce the same symptom. Use a multimeter to test each thermostat for proper continuity before ordering parts. Keep in mind that an RCA oven fan may run for more than an hour after cooking to cool internal components, especially after a high-temperature cycle. This normal cooling period does not necessarily indicate a failure. If the oven fan keeps running after the oven is fully cool, a defective control board relay, high-limit thermostat, or thermostat is more likely. For safe, accurate troubleshooting, disconnect power before testing or replacing parts. Enter your RCA oven model number to find the exact replacement control board, high-limit thermostat, or thermostat for your specific range, stove, or oven.

01 - RCA 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 - RCA 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 - RCA 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.

05 - RCA 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.

06 - RCA 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.
