If it has no continuity or it gives an OL reading on the multimeter, replace it.

the thermal fuse is mounted on the blower fan housing it detects the temperature of the air venting from the dryer to the outdoors, it will trip if the air becomes too hot (250+ Degrees) the thermal fuse always blows out because of an air restriction in the dryer, the vent tube, or the wall, most likely either:

  • Lint has caused a Build-Up.
