SOURCE: LG 1925 Microwave suddenly stopped cooking, other functions work fine!

What you said about the the clock leads me to suggest that you first unplug it for a few minutes then plug it back in. It may just need a good reset. If you don't have your owner's manual you can download one here: http://www.lge.com/support/manual.jsp The mention of odor concerns me. It may just be a bit of food or grease on the waveguide cover, which is a small sheet or panel on the wall or ceiling of the cooking cavity, but it may indicate the failure of a part in the high voltage section. You may have an intermittent door switch. You can see some of my other responses for info on how to get our important text file that helps you diagnose and repair door switches and gives important safety tips.

It's usually a bad door switch or a broken door switch mount. Once in a while it's due to a board problem. If you or a friend decide to work on it, we have *critical* safety, disassembly, and troubleshooting info (as well as a text file which helps in diagnosing and repairing door switch problems) at our site, which is linked at our listing here on FixYa: http://tinyurl.com/yzjozk

Same issue here. LMVM1935 about 2 months past warranty keypad stopped working. Apparently they need to add something in the manual about not boiling water on the range over which the microwave is installed (gee who would have thought that there would be steam over the cooktop and we should seal the membrane?).

The silver traces on the keypad got corroded and no longer conduct. After complaining to Sears (NO HELP) and LG (EVEN MORE INEPT) and running on 30sec button for about 6 months, I found a replacement keypad $30 w/ shipping and didn't break anything taking the door apart, thanks to the parts list link above. Thanks Rickzilla!

Life's Good, Their Keypad SUCKS, or apparently we are the only people that boil water anymore.

SOURCE: How do I replace a LG LMV1630ST microwave oven door handle?

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.

We're happy to help you with free advice and we'd appreciate your thoughtful rating of our answer.

Need a manual for a Lg microwave oven model LRM1260SW


No! there is no reset, the problem is caused by one or more door swiches that have become defective, or the keypad control board a possibility.

microwaves are really not cost efficient to repair. It's cheaper to buy a new one. Sears has comparable to your model starting at $70, walmart $60. :)

Our LG microwave (LMA 1560SW?LMA1560SB) has a door that won't open. The open button will push in, but not release the door - the plastic button cover pops back out, but just the cover - not the whole...


Mine did this too. Also, at times when I would shut the door, the whole keypad would go dark and the clock would have to be reset. There were also times when I would push Start and it would do nothing. I'd have to unplug it so it would reset itself.
I used a screwdriver and forced the door open. Mine is about 2 years old and it's now dead. Biggest piece of junk I've purchased in years. Really ticked me off, no more LG products for me. I had a Toshiba that lasted me 22 years and the only thing that went bad on it was the light stopped working and the fan cover fell off.

HI I HAVE A LG MICROWAVE OVEN MODEL# LMVM 2277ST ;1100W IT WORK BUT SLOW IT TAKES TIME TO WARM THE FOOD


I see by looking at the owner's manual there is an option to set power level from 0% to 100%, maybe that is set too low (see page 14 of manual). If don't have manual for that model (LMVM2277ST), can get from this web page (look near bottom of page and click words "owner's manual" that are underlined) :

How do i unlock my lg microwave i dont have an owners manual so i dont know how to unlock it


"Locked" meaning the buttons don't work/non-responsive (Child Safety Locked)? To Unlock/Disengage the Child Safety. Push and hold the "Clear/Off" button for 3 to 4 seconds. The Child Safety is disengaged - problem solved.

I have a 10 year old MH7130XE Whirlpool microwave oven. The oven and key pad both work, and the oven heats just fine. The problem is the oven begins running as soon as you open the door...without pushing...


I'm assuming you mis-typed and meant the oven begins running when you SHUT the door and stops when you OPEN the door. Please tell me this is what you meant! If the microwave oven runs with the door open, UPLUG IT IMMEDIATELY AND DO NOT USE IT!!!

If the oven begins running without pushing the start button then the controller is bad or the Start button is worn out and making contact without pushing it. (Most likely it is your controller.) Generally, it is not worth the cost to replace the controller on a 10 year old microwave. Probably time for a new one.

But if you want, you can call Whirlpool and see what they suggest at 800-253-1301.

If this was helpful, please select YES to the first two RATINGS questions. Good Luck!

How do i turn the turntable off?


You dont.
You can use spacers(nonmetalic of course) to raise the platter high enough to disenguage the drive. You can also shift the tray to one side on some models.

GE XL1800 Micro fan won't shut off after light burned out


The problem appears, at least in part, to the door latch circuitry which cannot be serviced by the owner. If the unit is still in warranty, call GE customer care. If not, replacing the unit is your best bet. I just bought a new GE 1100 watt oven with great features for less than $100 If the door dosen't latch correctly, you could be exposed to dangerous microwave energy.
