Dryer not heating up

mahubb810 depending on your exact model, the cooling light will normally stay on constantly during the cycle. It should begin blinking at the end of the cycle. Your dryers issue could be an issue with the moisture sensing cycle/sensor. We’ll need your exact model to see if there is an existing wiring diagram etc. to make determination about the sensor etc. as well as running a diagnostics program.

Cause 1

Thermal Fuse

The thermal fuse is a safety device designed to protect the dryer from overheating. The fuse is located on the blower housing or at the dryer’s heat source such as the heating element on electric dryers or at the burner on gas models. The fuse should be closed for continuity meaning it has a continuous electrical path through it when good. If overheated the fuse will have no continuity meaning the electrical path is broken and the fuse has blown. A multimeter can be used to test it for continuity. Be aware that a blown thermal fuse is an indication of a restricted exhaust vent from the dryer to the outside. Always check the dryer venting when replacing a blown thermal fuse.
