Gary February 26, 2016 for Model Number JVM1490SD003 GEProfile Space Saver How do I get access to the fuse. How does the black plastics grill at the top of microwave come off...over counter install in RV.
1 Answer Gary, To remove the air grill you would need to remove the screws at the front lip of the top of the microwave. If the unit is installed where the screws are not visible then the unit will have to be pulled out from installation in order to remove the grill. Read More...
Anthony February 06, 2016 for Model Number JVM1870SK03 Everything working just won't heat up. Thinking might be the fuse need help!
2 Answers Anthony, The fuse would not be the issue, if it was bad it would cause the entire unit to not work. The most likely cause for the unit to not work would be a bad magnetron. You can test the magnetron to make sure that it is good. The resistance should be less than 1 ohm. If greater than 1 ohms then the issue will be a bad magnetron. The magnetron part number is WB27X10880. Read More...

2 Answers Hello Anthony, This is most likely going to be the thermostat WB27X10810 located behind the air grille. Be sure to disconnect the power supply before attempting repair. Read More...
Dianna February 02, 2016 for Model Number PEB1590SM2SS I can't get the convection or the microwave to work. The light does come on but that is all.
1 Answer Hello Dianna. You will need to check the control board WB27X25300 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 Read More...
Chris J January 25, 2016 for Model Number PVM1870SM1SS Micro just went dead no power nothing. tested electrical receptacle has power. removed touch pad assy. The thermostat AP2026352 on right side bottom behind touchpad assy. little screw hold down on bottom frame back plug connector on thermostat is burned got hot plastic insulator melted slightly turned black. If this thermostat failed would it cause overheat of wire connector? If I replace thermostat and fuses might it work again? $250 for repair person to step in my door.maybe replace entire unit. Thanks Chris
1 Answer Chris, With the wire being burnt you would want to repair the wire and also would want to replace the thermostat. Read More...
Don January 21, 2016 for Model Number JVM1650BB005 Appliance lights up and appears OK but there is no heat. I tried to defrost a muffin and could not do it. Thanks for your help.....Don
1 Answer Hello Don. You most likely have a "high voltage" side malfunction. Transformer, diode, magnetron, Capacitor. You will need to be extremely careful if you decide to test the components with a multi meter, Very high residual voltage is present, so make sure you remove power to the microwave and short across the terminals on the capacitor. The magnetron should have a reading of less than 1 ohm resistance across the two terminals, and an "open" circuit between each terminal and chassis ground. The diode/rectifier should have a resistance reading in one direction only, no resistance, or resistance in both directions indicate a faulty diode. The primary winding on the trans former should read approximately 450 Ohms resistance, the secondary winding should read 80 ohms resistance, and the filament transformer should read 100 ohms resistance. If all the readings are proper and in range, replace the magnetron. Read More...

Becky December 11, 2015 for Model Number JVM1460WA001 HI, Microwave light and all buttons work perfectly. However the microwave does NOT heat. Is this a fuse issue or something else? Thank you, Becky
1 Answer Becky, This issue could be caused by a bad diode, transformer, capacitor or magnetron. You would want to test these parts using a multimeter on ohms setting. The resistance of the magnetron should be less than 1 ohm of resistance. The capacitor you would need to put a lead on either side of the capacitor and the resistance should jump up then fall to 0.
