Open the dryer door and remove the four screws located
vertically along the
inside lip of the door opening. These screws hold the front panel to
the front shroud assembly.
Once the four screws are removed,
grasp and press in on the upper edges of the front panel posts then
twist it inward to release the clips holding it to the cabinet. Tilt the
top of the front panel and move it away from the dryer.
Bypass the thermal fuse on the blower housing by disconnecting the wires and taping them together or connecting a jumper wire between them. Close the door then plug and start the dryer.
The dryer should start and heat up if the blower housing thermal fuse is the culprit. Otherwise, the other thermal fuse on the heater enclosure is blown. Unplug the dryer then bypass the thermal fuse on the heater enclosure in the same way the first is bypassed to confirm it.
Plug the dryer back then restart it. The dryer should start to confirm that the heater enclosure thermal fuse is blown. Replace the thermal fuse

Unplug the dryer and unbypass the blower housing thermal fuse then plug it back and restart it. If the dryer fails to restart, replace also the blower housing thermal fuse

) together with the cycling thermostat.
Reinstall the front panel in reverse steps of the removal steps to complete the repair.
