1Range/Stove/Oven Control Board
Most Common Solution
Repair Instructions:
The control board of an oven powers almost all of its electric parts. If this board is not working right, it might not send power to the fan motor. First, try to spin the fan blades with your hand. If they won't spin easily, the fan motor bearings may be locked up and the fan motor might need to be replaced. But, if the fan blades spin easily and an electrical tool called a multimeter shows that the motor is still good, then the control board is likely the problem. You can look at the board for any signs of damage or a broken part and replace it if needed.
How to Replace Range/Stove/Oven Oven Control Board
Shut off power to the rangeby locating the circuit breaker and shutting it off. This prevents electric shock.
Remove the control knobsby gently pulling straight up and off of the stems they attach to. Set aside.
Remove the control panelof the oven by locating mounting screws around the edges and carefully removing them.
Disconnect the wire connectorsattached to the control board by squeezing release tabs and gently pulling wires free.
Remove mounting screwsor other hardware securing the board in place. Lift out the old board.
Install the new control boardand attach with original mounting screws or hardware.
Reconnect wire connectorsto matching terminals, ensuring colors or locations match up properly.
Replace the control paneland mounting screws around the edges.
Reattach control knobsby pushing them back onto the stems.
Restore power and testovent functions like bake, broil, temperature controls.

2Range/Stove/Oven Convection Motor
Most Common Solution
Repair Instructions:
In a convection oven, the convection motor moves the fan to spread the air around inside the oven. If the fan isn't moving the air, the oven won't cook food evenly. Try spinning the fan blade with your hand. If it's hard to spin, this might mean the motor bearings are worn out. If they are worn out, you'll need to get a new convection motor. To see if the motor is broken, use a multimeter to test it. If the motor doesn't pass the test, you should replace it.
How to Replace Range/Stove/Oven Convection Motor
Disconnect power.Turn off power to the range at the main circuit breaker before working on any electrical components.
Remove fan housing cover.Unfasten screws or tabs to remove the oven's convection fan housing cover.
Disconnect wires.Unplug the electrical wires attached to the existing convection motor.Note wire positions.
Remove mounting screws.Use a nut driver or screwdriver to detach the screws or bolts securing the motor in place.
Extract old motor.Pull out the worn convection motor from the rear of the oven fan housing compartment.
Install new motor.Seat the replacement convection motor where the other was located and fasten securely using the mounting screws.
Reconnect wires.Plug the electrical wires back into the corresponding ports on the new motor as noted earlier.
Replace fan housing cover.Secure the convection fan housing cover with its retaining screws or tabs.
Energize system.Restore power at the main breaker and check that the new convection motor turns on as intended.
Test functionality.Operate the oven in convection mode to verify proper airflow from the replacement motor.

3Range/Stove/Oven Cooling Fan
Most Common Solution
Repair Instructions:
The cooling fan in a range helps prevent the range and its important parts from getting too hot. This fan is usually sold as a whole unit. If the fan can't spin easily or if it has power but won't work, you'll need to get a new one.
How to Replace Range/Stove/Oven Cooling Fan
Shut off power supply.Turn off power to the range at the circuit breaker to prevent electric shock while working.
Remove rear panel.Unscrew screws or bolts to remove the range's rear access panel, allowing visibility of internal components.
Disconnect wires.Unplug the electrical wires connected to the existing cooling fan.Note wire positions for correct reinstallation.
Remove mounting hardware.Use a socket wrench or nut driver to unfasten the nuts or bolts securing the fan in the range.
Remove old fan.Detach the cooling fan from its mounts inside the range cabinet.
Install new fan.Position the replacement fan where the old one was located and fasten securely with the mounting hardware.
Reconnect wires.Plug the electrical wires back into the same ports on the new fan as noted during removal.
Replace rear panel.Secure the range's rear access panel with its mounting screws.
Restore power.Turn power back on at the circuit breaker and check that the new cooling fan is operational.
Test fan operation.Confirm the replacement cooling fan turns on automatically when the oven heating elements activate.

4Range/Stove/Oven Main Control Board
Most Common Solution
Repair Instructions:
If the oven fan isn't working, the main control board might not be giving power to the fan motor. Before you replace the board, look at the wiring diagram first. People often mistake the control board as the problem when it's really not.
How to Replace Range/Stove/Oven Main Control Board
Shut off power to the range at the circuit breaker.Turning off power prevents electric shock during the repair.
Remove any knobs or control panelsby gently lifting straight up. Set hardware aside in a safe place.
Locate the control board,usually mounted under or behind the front control area.
Disconnect all wire connectorsattached to the board by squeezing locking tabs and pulling wires free.
Remove mounting screwsor brackets securing the board in place. Lift out carefully.
Insert the new control boardinto position and secure with original fasteners.
Reconnect all wire harnessesby firmly pushing connectors onto matching terminals.
Replace control knobs and panelsby pushing or screwing items back into position.
Restore power and test featuressuch as bake, broil, timers to ensure proper functioning.
Control board replacement is complete.Return range to normal operation.

5Range/Stove/Oven Blower Motor
Common Solution
Repair Instructions:
If the fan blades or blower wheel of the blower motor don't spin easily when you move them by hand, the motor bearings are probably stuck and you'll need to replace the blower motor. You can also use a tool called a multimeter to check if the motor is still good. If the motor doesn't pass this test, it's definitely broken.
How to Replace Range/Stove/Oven Blower Motor
