Lonnie for Model Number jvm1790bk01 When I set the time to cook with the control knob and push it to start it doesn't start, but starts the countdown. If I push the time to cook it will start, but stops, but will start again when pushed again. The Convection oven will set and start, but never heats up to the preheat number. What part do I need to replace to fix this problem?
Answer Hello Lonnie. You will need to test the door switches and see if they are bad and will need to be replaced. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
