When you say it stopped working , you mean no lights or display etc. Then that can be a fuse but fuses blow for a reason. Find the reason if the fuse blew.

If it's cooking when the door is opened, that's dangerous, but any defect needs to be addressed!

I would suspect a problem with a door switch or mount. The door switch help file is here.

If we knew what your model number was, we could possibly give you a link to the service manual.

So we can only give you generic help.

See these links before proceeding:

Here's a YouTube video showing how to remove a typical over the range control panel assembly in under 5 minutes.

If this is not enough to help, then please post a new help request with your full model number from the tag in or on the oven, and detailed symptoms.

if it does not power up, then it means its having a power problem. it might have worked fine in the past, but that's electronics for you. Power surge, irregular power supply, excess power supply, etc can affect the unit thereby not making it to power on.

This unit must have a power supply board in it where power enters from the mains. A capacitor, fuse, diode, etc may have been defective on the power board and maybe that's why its not making the unit turn on. There might also be some disconnection or something, inside the unit which is not making it to power on.

To actually find out what's wrong, you need to disassemble the unit with a screw driver and check what's wrong. You will be needing a meter in order to test the components on the power board, once you detect any bad component, you can make necessary replacement at any electronics accessories store withing our vicinity. This is the only way by which you can detect the problem.

Of course, testing the power board with a meter will require someone that has the ability. So it you can't, then you might be needing the help of a repairman or you can call a friend that has the ability to help you out.

I wish you the best of luck.

Take care.......

This is usually caused by either a bad door switch, a loose door switch mount, or a problem on the control panel.

Even though a door switch clicks, it may still be bad inside. Its continuity must be checked.

Switch or mount trouble can be caused by slamming the door or by opening the door while it's cooking without hitting the Stop pad first.

If you or a friend decide to look into it, we have critical information on safety, disassembly and door switches at our site, and our link is at our listing here on FixYa: http://tinyurl.com/yzjozk

We have the service manual for that model on our site at

You can ordre separate parts for the door or the whole door.

In searching for the service manual for this model, LG points us to the manual for model LMV1645 (here), so while it will be useful in disassembly and repair, I would contact Encompass here or call them toll-free at 866-779-5835 to be sure you get the right part numbers.

Good luck with it.

Look, i dont like to tell a non tech how to repair thir own microwaves as there are dangerous voltages sitting there that havent discharged.Step 1, if the magnatron goes faulty, it normally makes a loud growling sound and blows the fuses.So hopefully it isnt faulty. Most of the time i find the HVdiode damaged and to be safe, i replace the 1 micrifarad capacitor.as well. Before you replace that even, normally there is a single fusible wire that runs from the transformer to the cap. If that fuse is blown, have it replaced. Ask a friend who has a little electrical knowlege to help you please.

The lower door handle bracket broke and I'm trying to find out how to replace it. I already have the new bracket.
