The thermal fuse is a safety device designed to protect the dryer from overheating. The fuse is located on the blower housing or at the dryer’s heat source such as the heating element on electric dryers or at the burner on gas models. The fuse should be closed for continuity meaning it has a continuous electrical path through it when good. If overheated the fuse will have no continuity meaning the electrical path is broken and the fuse has blown out. A multimeter can be used to test it for continuity. Be aware that a blown thermal fuse is an indication of a restricted exhaust vent from the dryer to the outside. Always check the dryer venting when replacing a blown thermal fuse."
"The tech sheet that came with that dryer, ( a large foldout of nine pages on one sheet, front and back) indicated a technician’s diagnostic process, (turning power on to the unit, and then choose a control button, other than stop, {and presumably, Start}, press and hold five seconds, release and wait five seconds, (doing this process three times) would cause the machine to enter “diagnostic mode”…
my machine would NOT ENTER THAT MODE. The evaluation stated that failure to slip into diagnostic mode indicated a definite fault. From that point I was directed to ohm out the aforementioned devices with the conclusion that if alll checked good, replacement of the control access panel (touch panel used to choose settings) was required. Further instructions stated that if that still did not correct the problem, replacement of the power control module would be necessary."
