Anthony for Model Number LG Model #LMV1680ST Microwave Our LG microwave made a loud vibration noise than stopped working. Changed the fuse and all of the control panel functions worked: clock/light/options, but when the power button was pushed, the microwave vibrated loudly again for a few seconds then went completely dead. Do you know what may be causing this, or if it is common problem with this model?
Answer Hello Anthony. Based on the information you provided, it sounds like the magnetron 2B71165R is bad and will need to be replaced in the unit. You will also want to replace the diode 6021W3B001R with the magnetron and the fuse 3B74133Q. Hope this helps. Read More... Answered by AppliancePartsPros.com | Thursday, March 1, 2012
