Wax Motor

Door locked light did not come on and did not have 120 VAC across the Wax Motor. Also the Wax Motor did not extend out to make contact with the Door Lock, Spin Enable Switch. General guidance is to replace drive belt and to replace Wax Motor along with the Door Lock, Spin Enable Switches (total of two limit switches). This did not correct the problem. Checked for power and traced loss of power back to the Control Board where resistor R11 was found to be burnt out. Replaced Resistor with new Carbon Film unit, rating of 3.9 K-ohms, 1/4 W and 5%. As a prcaution, replace the Triac (manufactue part number NTE5657), component identified as Q6, rating of 0.8 Amp, 600 VAC. Semiconductor parts must be obtained from somewhere other than Parts Select (unable to find in the small town I live in, I located on the internet at Mouser.com). Unit works great now.

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.
