Maytag electric dryer model MEDC300XW0 with s/n M10811076
« on: April 19, 2021, 08:02:15 AM »

 I was given this dryer for repair with the customer telling me it would not heat or turn the drum. The rear cover was removed and the thermal fuse was checked. It was open and was replaced. The unit was plugged in to the power and the timer set on timed dry.  It started up and was heating properly. The door was opened and it shut off as normal. The door was closed and nothing else was touched but after a minute or so the heating element started glowing red to deliver heat but I had not pushed any control button. The heat continued but no blower  activation unless I rotated the timer knob to the off position  and it stopped heating  . I suspected the timer was the problem and removed it and dismantled it. All of the contacts were examined with no damage or burning  and the timer motor was tested to see if it was sticking or had a broken gear or cam. No problems were noted. Everything was put back together . The timer dial was set to the timed dry position at about 60 minutes. and it worked properly.  i opened the door and everything shut off as expected. I closed the door but did not touch the controls and after about a minute the heating element started glowing  to provide heat but there was no blower motor action.. If I turned the timer dial to the off position  all heat was shut off.    I am looking for advice on this model to see if anyone has had a similar  problem . I will next take the drum out and check for any problems but this start up of the heater without  the blower on or any dial requesting  drying is a strange one  . Can anyone offer any suggestions   ?

For what ever dumb reason ,I did not take the blower duct off the back of the unit when I started on this job. When I took it off I found it was almost  completely clogged with dirt and lint. After I cleaned it out the air flow was restored to the proper level. I still have the situation where the heater is on when I dont believe it should be . I dont know if I will replace all the sensor parts yet or not but still looking for advice.

I would check to make sure the heater isn't shorted to ground. I've seen them do that, and element will glow red with no input

I will recheck that aspect but so far that is not a factor.  When the timer is set to the ENERGY PREFERRED position it does not cause the problem ???
