How to Replace a Heat Sensor on a Kenmore Dryer

If a faulty heat sensor is the reason why your usually trusty Kenmore dryer won't heat, the only way to get your dryer working again is to replace the heat sensor.
If your budget won't allow for a visit from a Sears Kenmore authorized repairman, or if you are particularly adventurous, you can replace the heat sensor yourself in a relatively short period of time. The heat sensor replacement process can be completed without the use of special tools for just the cost of the replacement dryer component.

Step 1

Disconnect your Kenmore electric or gas dryer from its power source. Ensure that all electricity has been disconnected from your dryer before you begin the heat sensor replacement process. If you are replacing the heat sensor in a Kenmore gas dryer, use an adjustable wrench to remove the gas flex line from the shut-off valve before proceeding.

Step 2

Pull your Kenmore dryer away from the wall so that you can access its back panel. Unscrew and remove the screw at each corner of the back panel to free it. Set the back panel and screws aside until it is time to reassemble your Kenmore dryer.

Step 3

Look for the heat sensor between the blower housing and exhaust of your Kenmore dryer. The heat sensor looks like a white strip of plastic connected to two wires. Consult the Resources for an image of the internal components of your Kenmore dryer, including the heat sensor.

Step 4

Tug gently on the two connected wires to unplug them from the heat sensor in your Kenmore dryer.

Step 5

Free the faulty heat sensor from your dryer. Unscrew and remove the two screws that hold it in place. Throw away the faulty heat sensor before continuing the heat sensor replacement process. Reserve the two removed screws for reassembly.

Step 6

Align the screw holes in the replacement heat sensor with the screw holes on your Kenmore dryer. Replace and tighten the two screws to secure the new heat sensor to your dryer.

Step 7

Plug the two connected wires (the wires you unplugged in Step 4) into the new heat sensor.

Step 8

Reassemble your Kenmore clothes dryer to complete the heat sensor replacement process. Replace the back cover and insert and tighten the four screws to secure the panel to the back of your dryer. If you removed the gas flex line from your dryer's shut-off valve in Step 1, reconnect it at this time. Plug your Kenmore dryer back into an electrical outlet and run a short drying cycle to test the new heat sensor.
