Heat and lent were escaping excessively. Took the dryer apart and found several problems that all seemed to lead back to too much heat escaping and melting things that helped keep the lent where it should be and the drum turning properly and balanced. We replaced the front and rear felt drum seals, the blower seal, duct tape around the exhaust pipe, and the felt drum pads in the front. Put the dryer back together but left the top open. Ran the dryer a few seconds at a time. Found the drum turning incredibly slow but not sure why. The heating element got so hot so fast that it melted some of the rear drum felt seal in seconds and started to melt the plastic clips attached to the top panel. It appears the thermostat is directly above the coils and is no doubt being baked or already baked. How do we determine if the problem is the thermostat or the thermal fuse? Is there anything else we could have accidentally mixed up when putting everything back together that would cause this overheating? Thanks.
ANSWER Hello. You need to test the temperature coming from the dryer vent at the back of the dryer. It should go up around 150° and then start cycling back down. If not, you will need to check and make sure the heater is not grounded and staying on and see if the cycling thermostat needs to be replaced on the unit. Also, make sure there is good airflow coming from the unit.
