Car Nut When checking the defrost timer motor windings, if there is no continuity bewteen termials 1 and 3 is the unit good or defective? Mine has no continuity. The continuity between terminals 1 & 2 and 1 & 4 checks good when the timer is rotating per your instructions.
Answer Hello Car Nut. Numbers 1 and 3 should read closed for continuity, or show Resistance. They should not be open. Also, test and see if 1 and 4 is closed at the same time as 1 and 2. If so, the motor winding, which is open, has shorted the timer WP67001036. If you disconnect the wire number 2 from the timer and put the unit in defrost, and it still kicks the breaker, the timer is the problem. If number 2 is disconnected and the unit does not kick the breaker in defrost, there is a short to ground. Hope this helps. Read More... Answered by AppliancePartsPros.com | Thursday, July 28, 2011
