How to Install a Thermostat in an Electric Dryer

A faulty thermostat renders an electric dryer useless; thermostats regulate and monitor heat for your appliance to do its job. Replacing a thermostat isn't difficult, however. Learn how to do it at home and eliminate the repair bills.

Things You'll Need

• Replacement thermostat
• Screwdrivers (Phillips and flathead)

Instructions

1. Unplug the dryer's power cord from the wall connection. You will be working around the dryer's wiring, which can be dangerous if the power is connected.

2. Remove the rear cover of the dryer. Most dryers have four screws, one at each corner. Flathead screwdrivers will work for most models, but some require Phillips-head screwdrivers.

3. Locate the thermostat. The thermostat is circular or oval with a wire connection on each side. Remove the screws keeping the wires connected to the thermostat. Set them aside--you will be reusing them to install the new thermostat.

4. Disconnect the thermostat from the wires, then unscrew the thermostat from its mounting bracket. The thermostat will easily pull away from the wires once you have removed the screws. Discard the old thermostat.

5. Install the new thermostat on the mounting bracket. Be sure to tighten the screw enough to keep it secured. Connect the wiring to the thermostat and reinstall the screws to hold the wiring in place.

Tips & Warnings

• Make sure you purchase the correct thermostat for your electric dryer. The wrong thermostat can damage your dryer or cause a fire.
