Bill for Model Number JKP90DPWW Whirlpool Microwave/Built in Combination My 19 year old microwave, intermittently, will turn on when the door is closed. The light/carousel go on but the heating element will not. It can go a day or two and act normally, then all of the sudden it will turn on (not heating element). Other than that it works fine. If I close the door with food in it, the carosel/light will go on before I enter a cook time, etc. It allows me to enter the cook time and operates properly until it times out, then the carousel stays on until I open the door. I'm thinking it is one of the secondary switches? Thanks!! Bill
Answer Hello Bill. It sounds like either the latch or a door switch is bad and will need to be replaced on the unit. 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...
