Whirlpool stacked washer/dryer LTE5243DQ8. Heating element won't shut down with door open

7 posts in this topic

Hi all, and thanks in advance for your help.

I have a whirlpool stacked washer/dryer that had a blown thermal fuse. After changing the thermal fuse, the dryer ran normal EXCEPT...

If the door is opened while the dryer is running, the heating element does not turn off (everything else does). Element functions normally during the cycle and will shut itself off at the end of the cycle, but the door switch isn't communicating to the element apparently. I assume this is how the thermal fuse blew in the first place.

Thoughts?

Did you check if the heating element is shorting to ground?

I didn't think of that. Since the element works properly when the door is closed, I assumed it had to be something to do with the door switch circuit. How would I check to see if the element was shorting to ground?

You will see the actual element touching the heater element bracket.  Another way to tell is to set your meter on the continuity scale, touch one lead to one wire of the element, and the other lead to the bracket and you will get continuity. You are supposed to get an open circuit.

Oh ya. Gotcha. I'll try that. If that were the case though, it seems to me that the element would run wide open at all times. It glows faintly when the dryer is running normally (door closed) but as soon as the door is opened, the element glows twice as brightly. Quite the fire hazard since the blower switches itself off. Thanks for the advice! I'll let u know what I find out. It's a rental so I have to drive over there and check it out tomorrow.

I would check the AC cord hook up. With 3 wire and 4 wire installs, I find many errors.

  The only way the heater coil can be powered with door open (motor off) is if the motor heat circuit switch is stuck closed, the wire between the heater coil terminal and motor connector is shorted to ground or the heat coil is touching ground.
