A blown thermal fuse is the most common reason a dryer suddenly stops heating or won't start at all. The thermal fuse is a one-time safety device that trips when the dryer overheats — and a clogged vent is almost always the underlying cause. Our technicians replace the fuse and inspect the vent system to prevent it from happening again.
The #1 cause of blown thermal fuses. Restricted airflow causes the dryer to overheat, tripping the fuse.
If the cycling thermostat doesn't regulate temperature properly, the dryer overheats and blows the fuse.
A heavily clogged lint screen reduces airflow enough to cause overheating.
A shorted heating element can generate excessive heat that trips the thermal fuse.
Try these before calling for service — they may resolve a simple issue.
