George for Model Number 110.78632700 The timer will not advance while it is running. It will not shut off unless I open the door or manually rotate knob to off. Could it possibly be anything else besides the timer?
Answer Hello George. Test and see if there is power coming to the timer motor. If so, and the motor does not turn, you will need to replace the timer WP3976576. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
