This dryer repair guide explains how to replace the thermal cut-off fuse in a gas dryer. The thermal cut-off fuse is a safety device that shuts down the burner if the dryer severely overheats. The dryer severely overheats if the high-limit thermostat failed to shut off the dryer when the burner began to overheat. You can't reset a blown thermal cut-off fuse — you must replace it, as well as the failed high-limit thermostat. The thermal cut-off fuse kit contains both components, and the step-by-step instructions in this repair guide show you how to replace them in a gas dryer, using a manufacturer-approved replacement part.
Use this procedure to install a thermal cut-off fuse kit in Kenmore, Whirlpool, Maytag, Amana, Roper, Crosley and Estate gas dryers with a lint screen housing located in the top dryer panel.
If you have an electric dryer, see the repair guide How to Install a Thermal Cut-off Fuse Kit in an Electric Dryer.
