What causes a thermal fuse to blow in a dryer?

A dryer thermal fuse typically blows due to excessive heat, often caused by restricted airflow. Common reasons include a clogged lint screen, a blocked dryer vent, or a malfunctioning heating element or thermostat that fails to regulate temperature properly. Addressing the root cause is important to prevent repeat failure.

Can I bypass a dryer thermal fuse?

Bypassing a dryer thermal fuse is not recommended and can be dangerous. The fuse is a critical safety component designed to prevent fires by shutting off power if the dryer overheats. For safe operation, always replace a blown thermal fuse with the correct part.

How do I test a dryer thermal fuse?

To test a thermal fuse, first disconnect power to the dryer. Remove the fuse and use a multimeter set to continuity mode. Place the multimeter probes on each terminal of the fuse. A good fuse will show continuity (a beep or a reading close to zero ohms), while a blown fuse will show no continuity (an open circuit).
