Mickey for Model Number GT4175SPB-0 My microwave oven stoped working. CTRL pattern looks fine. When hitting "START" button, light comes on and the clock starts countdown. However, table does not turn, no heating. What could be broken?
Answer Hello Mickey. It sounds like the door switch 4392027 is bad and will need to be replaced. You will need to test and see which switch is bad. 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...
