Customer Questions and Answers for Microwave Door Handle by Ge

Hello Barbara. Test and make sure all the thermal fuses inside the unit read closed for continuity. If so, test the magnetron WB27X10735. It should read less than 1 ohm. If not, you will need to replace the magnetron and the diode WB27X1160. 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
