Our LG over the stove microwave oven LMHM2017ST is powerless.

What happened was it ran for 12 minutes on high with nothing in it. Someone forgot to put the corn on the cob inside. After realizing this I opened the door. It was hot inside but no doors at all. I inplugged it and let it cool down. The microwave has no power. We replaced the fuse, no luck...help please.

A thermal protector on the magnetron may have opened. Normally, these reset within a few minutes. If you've had the oven off for more than an hour, and it's still lifeless, then you may have a bad connection somewhere. A defective magnetron will not cause an oven to be dead if the main fuse has been replaced - at least not immediately.

SOURCE: Microwave Oven Interior Paint

Yes, but if this is not fixed, it may flake off and get in your food, or allow grease or food particles to build up on the surface.

 

The loose paint should really be sanded off, at least.

 

Then when it's clean and dry, you can apply a little high-temperature appliance paint, available from department stores, home improvement centers, and appliance parts stores.

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 someone you know 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

There should also be a very helpful "mini-manual" hidden inside the unit behind the control panel. It's very helpful when troubleshooting.

If it went dead almost immediately after pressing the Start pad, that\'s usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that\'s usually a failing high-voltage transformer.

Here are some links you or someone you know can use for test help, but read their safety warnings first:

SOURCE: Ewave over the stove microwave fuse blows when I

The light is the only thing that comes on when you open door. You either have a shorted door switch (Micro switch) or a shorted bulb. You have either a shorted bulb or bad socket. From my experience, it's the bulb. Just because it may seem to start to come on when you open the door, it's most likely bad. At least it not expensive.
Please rate solution

Testimonial: "Thanks, yes the light comes on for a second then fuse blows. I'll replace it, thanks!"

How to remove door COVER from door of LG Microwave model LMHM2017ST

Here are the steps to remove the door cover from the door of your LG Microwave model LMHM2017ST:
  1. Unplug the microwave from the power source.
  2. Open the microwave door and locate the four screws on the inner edge of the door.
  3. Use a Phillips screwdriver to remove the four screws.
  4. Carefully separate the outer door panel from the inner door panel.
  5. You will now see the door cover attached to the outer door panel.
  6. Use a flathead screwdriver or plastic pry tool to gently pry the door cover off of the outer door panel. Start at one corner and work your way around the edge.
  7. Once the door cover is removed, you can replace it with the brushed silver cover from the new door.
  8. To reassemble the door, simply snap the new cover onto the outer door panel and then reattach the outer door panel to the inner door panel using the four screws you removed earlier.
Make sure to be careful when removing the door cover, as it can be fragile and may break if handled roughly.

Reset lg microwave LMHM2017ST

As far as I am aware, you can reset the microwave entries with the STOP/CLEAR button. This is the only way to clear all entries on the oven.

Why can't you run a microwave without anything in it? What happens and can you fix the problem? I forgot to put the food in and ran it for 4 minutes with nothing inside. Now it won't heat any food.

A microwave oven works on the principal of a high power high frequency radio transmitter. The device that emits the microwave energy is a tube called a magnetron . When you run the microwave empty with nothing to absorb the microwave energy it is all reflected back to the magnetron causing it to overheat and destroy itself or cause failure in the High Voltage power supply due to excessive current draw.This is caused by standing waves.

I have LG lmhm2017st microwave and some times the buttons won't work but now it inputs 11:11 start all by it self over and over again . If I leave it unplugged for a few minutes it will start to work...

If you have warranty use it asp, from the description the problem is in the keypad "membrane shorting" or the microprocessor control board is becoming intermittent, it will get to the point and stop functioning.

My LG over the range microwave doesn't heat any more

When the microwave sounds okay, but there's no heat, one of the internal door switches, the high voltage circuitry, or the circuit board may have a problem. To resolve this problem, you need the assistance of a qualified appliance repair technician.
That said, you can get free estimates on the cost of a repair but you should also consider a replacement which may be a better option for you.

What they do not tell you about over the stove microwaves is that they are constantly deteriorating due to the steam, oil, and other cooking fumes from the stove below. As a result, their life expectancy is definitely diminished.
