Dryer will not heat. (Sort of a long story) Had service tech work on dryer. He said the thermal cutoff was bad and ordered another one. Several days later he showed up but forgot the part… Several days later they called to reschedule due to vehicle problems. We asked them to send part. Several days later we received the thermal cutoff ($0.60 postage due) After installing the part the dryer would run, burner would work but would not dry clothes. Clothes did not feel very hot. In desperation, we ordered and installed the thermistor and moisture sensor. Same problem. We called different repair tech. This guy said that the vent was partially obstructed. (It was a flex pipe). We purchased and installed a much better vent tube. Dryer now will run but the burner would not. Checked and found the thermal cutoff was open. ??? Ordered and installed new thermal cutoff. This one failed before drying one load of clothes. In absence of an actual schematic I am at a loss as why the thermal cutoff would fail at all and now so quickly. Is it heat, or high current??? Do you have a possible solution? I am tired of waiting and paying service techs that apparently are, well, not so good.

ANSWER Hello Randy. Usually this is due to a restricted vent in the unit. Remove the vent pipe and make sure the air duct assembly and the blower wheel is clean on the dryer. Then run the dryer with the vent unhooked and see if it blows the cut-off. If not, venting issue.
