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.
