Steve for Model Number MDE6700AYW Would partial failure of this item allow the dryer coil to overheat and burnout the coil thermal fuse ? I have new duct dryer vent ductwork and no blockage in the flexable alum duct. I have replace the thermal fuse and regained use of my dryer but now it is blow again. I have read the resistance and it is close but not at the required so I am wondering if there may be further degridation of the control when it heats up.
Answer Hi Steve. It sounds like the thermistor which will ohm out to 10,000 ohms cold +/- 10 %. It is part # WP35001191. What can be sticking on to allow the overheat is a concern. Is the vent kinked when pushed back in ? Look at it in position. Is there a bad blower wheel that is scraping and needs changed part # DC67-00180B. The air flow movement is a very tightly needed calibration. The heater relays have been known to stick shut and allow over heat part # WP35001153. Use the tech. sheet supplied inside the unit to see if there are any diagnostic codes showing. It has been my estimation the control board relay is more the issue. If you did had a restricted vent right before the vent cleaning and the motor is clogged , then the heater expansion has already taken place for so long that it only now takes a little heat to relax it enough to over heat and short out. Element part # WP35001247. Thank You. Read More... Answered by AppliancePartsPros.com | Friday, February 17, 2012
