Universal Oven fan not working

Is your oven fan not working? First determine which fan has stopped: the cooling fan that protects the range, the convection fan inside the oven, or an exhaust or blower fan. The most likely cause is a defective control board that is not sending voltage to the fan motor. Turn the fan blade by hand. If it does not turn freely, seized motor bearings may be the problem. If the blade turns freely and the motor has electrical continuity, inspect the control board for damage and check the wiring diagram before replacing it. A failed cooling fan is another common cause, especially when the fan has power but will not run. For a convection oven fan not working, test the convection motor for continuity and replace it if the bearings are worn or the motor has no continuity. A faulty main control board, exhaust fan motor, or blower motor can also cause an oven fan not spinning. Use a multimeter to test suspected motors safely. Enter your range, stove, or oven model number to find the exact replacement fan, motor, or control board for your appliance.

01 - Universal Range/Stove/Oven Control Board

An oven's control board sends voltage to nearly all of the oven's electrical components. If the control board is defective, the voltage may not be sent to the fan motor. You should first attempt to rotate the fan blades by hand. If they do not turn freely, it's likely the fan motor bearings have seized and the fan motor will need to be replaced. However, it the fan blades do turn freely and a multimeter shows that the motor itself tests positive for electrical continuity, then the control board is probably at fault. You can inspect the board for signs of damage or a shorted component and replace if necessary.

02 - Universal Range/Stove/Oven Cooling Fan

The cooling fan runs to help keep the range itself and its critical parts from overheating. The cooling fan is often sold as an assembly. If the fan does not turn freely or has power to it but won't run, it will need to be replaced.

03 - Universal Range/Stove/Oven Convection Motor

In a convection oven, the convection motor drives the convection fan to circulate the air inside the oven. If the convection fan isn't circulating the air, the oven won't bake evenly. Try turning the convection fan blade by hand. If the blade is hard to turn, this may indicate that the motor bearings are worn. If the motor bearings are worn, you will have to replace the convection motor. To determine if the motor is defective, use a multimeter to test it for continuity. If the motor does not have continuity, replace it.

04 - Universal Range/Stove/Oven Main Control Board

If the oven fan is not working, the main control board may not be sending power to the fan motor. Check the wiring diagram first before replacing the board. Control boards are often misdiagnosed.
Highly Likely

05 - Universal Range/Stove/Oven Exhaust Fan Motor

If the exhaust fan motor has power to it but it's not turning, the windings or bearings may be bad. Try turning the fan blade by hand. If the fan blade does not turn freely, or the motor keeps shutting off when it has power to it, the exhaust fan motor will need to be replaced.
Highly Likely

06 - Universal Range/Stove/Oven Blower Motor

If the blower motor's fan blades or blower wheel do not turn freely by hand, it's likely the motor bearings have seized and the blower motor will need to be replaced. You can also use a multimeter to determine if the motor has electrical continuity. If the motor has no electrical continuity, the part is definitely defective.
