WARNING: Before checking or testing any
parts, be sure to disconnect your range from its power source completely and
shut off the gas.
If you’re having problems with your oven fan not turning
off, here are some possible causes to why your fan is staying on:
This part sends voltage to your oven fan as the appliance
heats up. If the part is damaged it might keep sending volts to the oven fan
even after your unit has cooled off. Use your owner manual to locate the
thermostat, and use a multimeter to check the thermostats continuity. If it
does not have continuity, then it may need to be replaced.
This part of the oven regulates power to your fan, bake, and
broiler according to whatever settings you have placed on the display. If one
of your relays have shorted out, the control board might send consistent
voltage to the fan.
