The microwave still operates but is not heating the food at all.
Answer Hello Kathy. You will need to test the magnetron 6324W1A001M and see if it is good. With the meter set on Rx1 you should read less than 1 ohm with the wires disconnected. Also test the diode 6021W3B001V. It should only read in one direction. Test the sensor assembly 6501W1A013A if both the magnetron and diode are good. It should read closed for continuity. 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
