Door problem on Maytag stacked washer/dryer

This is a Washer/Dryer stack unit. Had trouble with the power light not going off automatically. Had to press the power on/off switch to get it to turn off and allow the door to open. While this was going on, the washer would rotate every few seconds and would continue this until the off switch was pressed. Tried replacing the door lock enabler switches and the timer. This did not help. Finally smelled an electrical odor and found that the mother board (located in the upper right front part of the dryer) had a burned resistor (R-11) When this happens, it requires replacing the wax motor and the mother board. This corrected the problem. If you do have problems with the door lock, I would suggest replacing the wax motor as soon as possible. If the wax motor isn't replaced it may burn the new mother board. If I had replaced the wax motor initially, I doubt if the mother board resistor would have burned. Works fine now.
