Cesar for Model Number MT4140SKT My Whirlpool microwave oven works on everything except it is not heating. What do you think is the problem?
Answer Hello Cesar! If the microwave is not heating it could several different parts. The main parts you will need to look at and test is the magnetron W10859575, transformer WPW10170369 and high voltage diode WP8205489. You can test the parts using a multimeter MA-DM1. Here is a link from our free repair forum you can refer to for help with using a multi meter. Hope this helps, thanks! http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
