okay prefect. unplug the dryer and remove the access panel number 61 on this diagram. there are screws at the very bottom. then you will see the blower assembly, the thermal fuse is number 59 and its on the top of the blower between the blower and the drum. remove the wires and test it for continuity.

It can if the fuse is bad. have you tested it yet ?
