My microwave runs but does not heat. What's wrong?
Answer Hello Linda. You will need to test the magnetron and the diode in the unit. The magnetron should read less than 1 ohm and the magnets do not need to be cracked. The diode should only read in 1 direction in 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
