Dryer Not Heating? Check Dryer Thermal Fuse On Back

If suddenly your clothes dryer has stopped drying your clothing, check the thermal fuse on back. Usually the dryer will STILL work in every aspect EXCEPT it will not dry. This means that it will still “tumble” and it will seem as if it is working properly. You will usually find this out after the dryer has “buzzed” to tell you it is done drying your clothes. You will open up the dryer door expecting dry clothes but they will be just tumbling in the dryer and not getting any heat to dry them.

What is a thermal fuse and what does it do? A thermal fuse is a small electrical temperature sensitive switch that is made to interrupt electrical flow when heated to their specific rated trip temperature. A thermal fuse is in place for safety. A thermal fuse is similar to an electrical fuse. Thermal fuses are single use safety devices that can’t be reset and must be removed and replaced when it trips.

What would cause the thermal fuse on my dryer to trip? Usually the thermal fuse will trip when the vent system is clogged. This will usually be the most common reason and cleaning out the dryer vent is usually all that is needed to fix this issue and prevent the thermal fuse from tripping again.
