Jenn Air Oven fan not working

If your Jenn Air oven fan is not working, the control board is the most likely cause because it supplies voltage to the fan motor. First, turn the fan blade by hand with power disconnected. If it does not turn freely, the fan motor bearings may be seized. If the blade turns freely and the motor has electrical continuity, inspect the control board for damaged or shorted components. A failed cooling fan is another common cause of an oven fan not spinning. Replace the cooling fan assembly if it has power but will not run or the blade binds. For a convection oven fan not working, test the convection motor next. Worn bearings or a failed continuity test indicate that the motor needs replacement. The main control board may also fail to send power to the fan, but check the wiring diagram before replacing it. Less common causes include a defective exhaust fan motor or blower motor with failed windings, seized bearings, or no continuity. Enter your Jenn Air range, stove, or oven model number to find the exact replacement fan, motor, or control board for your appliance.

01 - Jenn Air 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 - Jenn Air 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 - Jenn Air 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 - Jenn Air 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 - Jenn Air 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 - Jenn Air 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.
