How to replace a dryer thermistor

Unplug the dryer. If it's a gas dryer, shut off the gas.

To release the clips that hold the service panel in place, push a putty knife into the gap above the service panel on each end.

Pull the top of the service panel forward and remove it.

Pull out the lint screen.

Remove the screws that secure the lint duct assembly to the lint duct housing.

Pull the lint duct assembly out of the dryer and set it aside.

Locate the thermistor atop of the blower housing. Carefully remove the wires from the thermistor.

Using a 1/4-inch wrench, remove the mounting screws that secure the thermistor to the top of the blower housing. Remove the thermistor and set it aside for disposal. 

Position the new thermistor on the blower housing and fasten the mounting screws.

Connect the wires to the new thermistor—it doesn't matter which spade connectors you attach the wires to.

Place the lint duct assembly in its housing. Insert the mounting screws and tighten firmly.

Reinstall the lint screen.

Line up the bottom lip of the service panel with the base of the dryer.

Push the top of the service panel to engage the locking clips.

Plug the dryer into the wall outlet. If it's a gas dryer, turn on the gas supply to the dryer.
