Joel September 11, 2013 for Model Number jnm151sm5ss I have power going into my microwave, but nothing comes on. I checked the fuse its good I checked the first small circuit board and there is power coming from there. I dont what else to check.
1 Answer Hello Joel. You need to check and see if any of the thermal cut outs are bad. If so, they will prevent the unit from coming on. Read More...
Tzel March 24, 2013 for Model Number jmv1540sn1ss My microwave turns on but won't get hot. Is it a fuse or a diode problem?
1 Answer Hello Tzel. You need to test the diode, should only read one direction. If it is good, check the magnetron in the unit. Should read less than 1 ohm and have no cracks in the magnets. 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 Read More...
