LG LMV1630ST Microwave Oven - Answered Questions & Fixed issues

If the microwave buttons don't work the touchpad and control panel assembly are probably defective.

The problem is in the keypad control board and must be replaced, I would consider cost before you allow the go ahead.

It sounds as if the display board is faulty.

Be very careful around microwaves they have very high voltage inside them that can be deadly. As for the control panel its very common for grease and oil to get behind the plastic film of the control panel, once it does the buttons will stop working since the grease insulates the contacts. Unplug it from the power, let it sit for 60 minutes to make sure all power from the high voltage caps has dissipated. Get access to the back of the control panel. You will probably have to peel back the control plastic on the front to get behind it. One behind clean all the buttons and contact areas. Reassemble, and it should work.

The door comes in parts not the whole door. All you have to do is remove the plastic liner around the glass and you can get to the screws that hold the door in place. Go to sears web site and you can order the parts thru them they are pretty good about getting the parts for you

disconnect from power,then remove the cover and test the fuse and the grounding diode for failure then replace but if still not heating then replace the magnetron.

Change Bridge Rectifier Diode And Capacitor Without Test by Meter,Some Time it will licks,Check All Connected Parts,And Last Is Transformer

That would likely be a shorted high voltage diode or failed magnetron. Replacing the high voltage diode would be economical, but on most counter top ovens, replacing the magnetron would likely not be. But the service manual is here: http://elektrotanya.com/lg_ms1927c.pdf/download.html Here are a a couple of good help links: http://www.microtechfactoryservice.com/diode.html http://www.microtechfactoryservice.com/mag_test.html You can order LG parts from Encompass here but since the service manual does not have part numbers, it would probably be best to call Encompass toll-free at 866-779-5835.

see the next steps , use the VOM for fix it. God bless youIf your microwave is turning itself on, the first thing to check is the interlock switch. This is usually the first thing to malfunction that could cause this issue. If the interlock switch is bad then it will need to be replaced.

Main control boardIf your microwave is turning itself on and the interlock switch is still working, the probable cause is the main control board. If the control board is defective it will need to be replaced.

Magnetron, the diode most use, or the large ac filter cap are all possible.most people cannot test or even in some cases get at those

A suggestion---call or contact LG to see if what you want is even available---only other (a little crazy) is consider if metal having the handle removed and chromed.

try using a small potato,push it into the base while turning the potato.it may lock onto the base and unscrew it....UNPLUG IT FIRST...

see the video and proceed according. God bless you

see the picture. and fix it. God bless you

probably a main board issue. check voltage to the board if there is voltage then the main board is bad
