Trouble shoot why my LG LMV1630ST stoped working

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

Unfortunately, about the only thing you can do is to replace the switch. We don't service microwaves that often so I am not to sure of where the switch is located on your unit. So here is the layout for your unit, and you can find the correct switch on the diagram and then look it up on the right side.

On model LMV1630ST, it's located on the filter circuit board in front of where the cord comes into the unit.

You'll need to remove the oven from the wall, then remove the outer cover of the oven.

You can find the service manual at our site here.

You should consult your installation instructions.

If for some reason you don't still have your installation instructions, you can download them here.

Normally you have to separate the door panels (as shown in the attached photo) and then you'll see the screws you need to remove.

Or you can watch a YouTube video (not a video I made) here that demonstrates how it's done.

under the outer cover,its either a 10-15-or 20 amp ceramic safety fuse avail at most hardware stores, the amp rating is on the side of the fuse, if the new one blows then either the H.V. diode/capacitor or the magnetron can be suspects

The first thing I would suggest is a hard reset. Unplug the unit for a minute or so. Then plug it back in, set the clock and try again.

If that doesn't work, leave it unplugged for about 5 minutes.

Is it a US model (made for 60HZ power) being used overseas (50HZ power)?

please use this link to view another servicemans explanaton of what your problem is and hopw to address. In essence, you should ALWAYs press the stop button before opening the door... Hope this helps you...

I'm confused. If it's 6 weeks old, you can get it repaired free.

If it's 1-1/2 years old, the manufacturer will cover the part cost of the magnetron (assuming that's what's wrong) and you will have to pay for labor and any other needed parts.

Also, the subject line mentions a model LMV1630ST while your message body mentions model LMV1680BB.

For Goldstar / LG / customer service, help, call 1-800-243-0000 (M-F, 7am-8pm CT, Sat 8-5 CT) and choose the appropriate prompt from the menu or visit here.

Chances are your problem is a bad magnetron, but it may be another high voltage part.

Make sure the door is aligned and closes safety switches.
