Mark for Model Number MEDC200XW3 I have a MEDC200XW3 that runs as soon as the timer is advanced without needing to press the start buttons. The dryer also runs with the door open, and even with the door switch disconnected. On top of this the heating element won't energize. I've replaced the heating element and all limits/thermostats (dryer worked fine after this for a few days). Most recent repair was replacing the motor. The timer reads open/closed correctly. Start switch and door switch only read closed when depressed. What is left to check?
Answer Mark, it would be recommended that the wiring is checked for a grounded out connection. Based on the information provided, as the door switch is operating properly the motor should not be able to operate unless there is a grounded connection somewhere between the motor and the door switch. In regards to the element not energizing, once the wires are checked for any grounded out connections as well as ensuring the wires are connected to the necessary terminals, the terminal block would need to be tested for 240VAC from the black wire to the red wire. If there is not 240VAC, the next step would be to test each side to neutral to identify where there is not 120VAC. If there is 240VAC, and the wires check as being connected properly, the last possibility would be the timer WP8299779. Read More... Answered by AppliancePartsPros.com | Thursday, April 16, 2020
