If the microwave has power...lights...turns etc. but does not heat, is the problem a bad magnetron?
Answer Hello Steven. Yes, it could be the magnetron on the unit. You can test the magnetron. It should read less than 1 ohm. 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
