1 Answer Anthony, Yes, if you are getting 120 vac to the control board but the display is not working then the control board would need to be replaced. The part number for the control board is ACM49437018. Read More...

Jay S. January 03, 2014 for Model Number LMV1630BB My turntable stopped rotating, pulled off the little motor from underneath the unit, hot wired it and it rotated, but it will not work connected to the unit, is there a separate, small fuse for this connection. Everything else works. Thanks
Deb J December 27, 2013 for Model Number 72167680790 Kenmore Microwave The under stove lighting will not work. Have tested unit to see if electricity is getting to it. I have a part 6877W3S001A which is a leadwire assembly. The wiring going to that assembly tests good for power. That assembly tests good sometimes, then others no, but when bulbs are inserted no go. When I touch the light on pad, it beeps and offers me low or high, but lights do not turn on. I have looked for a leadwire assembly but can't find one. What do you think the issue is???? Please let me know, I need those lights in my dark kitchen. Thanks, Deb
1 Answer Hello Deb. Based on the information you provided, the board 42QBP4796 is bad. This part has been permanently discontinued by the manufacturer and we don't know of any source or replacement for the part. Read More...

Mgs January 29, 2013 for Model Number LG LMV 1680 BB My LG LMV 1680 microwave stopped working. The microwave was in operation when I heard a loud pop. After that, the microwave just doesn't power up. Checked the breaker and the electrical outlet. They are fine. Nothing visibly wrong inside the microwave (no fire, smell, etc) The front plastic window on the door had come down about an inch. I took the door off, applied glue to the broken tabs and put it back up. Still nothing. I suspect the fuse is blown. I can replace it but what could have caused it to trip? It may not have been the window sliding down. Could it be one of the door switches (this model seems to have 3)? Wanted to order additional parts if necessary when I'm ordering the new fuse. Any insights or direction would be greatly appreciated!
1 Answer Hello MGS. Test the door switches and make sure they are good and test the magnetron 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...
Gordon January 15, 2013 for Model Number lmv2053sb My microwave is only 4 years old and everything works except there is NO HEAT. Is the fuse the problem?
1 Answer Hello Gordon, If the fuse were bad the unit would be completely dead. In the case of the unit working except for heating, the problem is a high voltage issue. This includes the control board, the high voltage transformer, the high voltage capacitor, the high voltage diode, the magnetron high temperature cutout, and the magnetron. One or more of these can be the issue. The only way to know for sure is to open the unit, discharge the high voltage capacitor to ground, and test the individual components. According to the manufacturer, there is no definitive test for the magnetron other than testing to ensure the terminals are not shorted to ground, (chassis). Read More...
