What People Are Saying

Rated 5 out of 5 by from Love the looks and features Love the way it looks in my kitchen,always wanted a LG product

Rated 2 out of 5 by from Really loud We have been using this microwave for about a month now. It is much louder than the one we had, it also sounds like something is rattling inside.Which is very disappointing. Also the clock is set in and very dim, hard to see unless you're standing right in front of it. It does heat things up so that's the important thing.

Rated 4 out of 5 by from Love the different options I am very happy with my microwave the only thing that could be improved on is the shelf on the inside I think it is to flimsy and not very easy to use I took it out otherwise I am very happy with this appliance

Rated 5 out of 5 by from Easy install and love the "touch screen" buttons. We replaced our old unit that gave up after fifteen years and figured it would be a lot of trouble to find something that fit in the same space. Wow it was so easy as they are standard size and light weight! The buttons are touch screen style and so easy to use. The unit is quiet even when running the fan. We've had it a week so far and just love it! This is our second LG appliance and will probably continue to up grade other appliances to the LG family.

Rated 3 out of 5 by from Nice appearance Bought this OTR Microwave August 1. Still getting used to it. Major shortcomings were: 1) the 3" long bolts were not long enough for installing the OTR because my facing board under the cabinet above the OTR was too high. The bolts wouldn't engage the fitting in the top 2-corners of the microwave. When I contacted LG Customer Support they were no help and without the tread size stated in the bolt description (only showed 1/4"x3"), I was left to fend for myself. 2) the filters are extremely flimsey. Actually, we were cooking a pot of crab soup on one of the back burners which takes hours when we observed that the filter had distorted severely. This was reported to LG and although they replaced the filters, the problem remains that the design is not robust.

Rated 4 out of 5 by from great product works great, the only thing we don't like is that the digital clock shuts off after a few minutes. the clock is at eye level and can be seen from nearly everywhere in the kitchen, it would be nice if it stayed on. LG's excuse is that it save energy, however messages like "cook end", "end", stay on forever. The tiny amount of electricity a digital clock uses is so small, it's pointless.

Rated 5 out of 5 by from Works well so far 1 year in, we are pleased as it works as advertised. Seems like a quality product at a good value, which is why we bought it after much research and reviews. Only negatives would be that the window is too dark to actually see inside if you're wondering about the status of what is being heated and the exterior finish was rubbed down on the corner when we received it, apparently from during shipping. Since we didn't notice it until we had hung it, didn't mess with it as we didn't want to take it back down and wait for another to be delivered.

Rated 1 out of 5 by from Terrible Quality - DO NOT ORDER! When updating my kitchen last year, I purchased this microwave in stainless steel black along with the matching fridge, stove, and dishwasher. They haven't even been installed a year yet and not only is the black stainless steel covering peeling from all of the appliances including this microwave, but the handle of the microwave actually disconnected on the bottom when I went to open it! I was shocked as they haven't even been installed and been used a full year! Needless to say I was not happy, and when I called LG to see if it was covered under warranty they told me it wasn't because the manufacturers warranty is only good for one year. We purchased everything in July but did not have it delivered and installed until November when the rest of my kitchen was complete. It's clearly a manufacturing issue, but LG doesn't want to help me in any way to get this issue resolved. Needless to say I will never buy LG products again, terrible!!

Can this unit be used over a gas range does it require an outside venting or can it recurlate.

Asked by: Gene 14
This unit would not need an external vent to be connected. There would be no reason as to why it could not be installed over a gas range. We do recommend reviewing the installation and clearance requirements prior to having the product installed to ensure the unit is within the clearance requirement specification. This information may be found under the support tab. A copy of the owner's manual is available for downloading.

I just purchased this microwave but I don't want to use the venting feature. Can I disable the auto vent so it won't ever come on?

Asked by: jman2002
We appreciate your interest in the microwave. The "Vent On/Off" can be used to cycle the ventilation on or off as desired, but If the microwave is cooking, the vent fan turns on automatically if the sensors detect too much heat from the cooktop. This is designed to prevent microwave component damage and cannot be deactivated.

I've had this microwave just one year. Today I touched the energy saver button and now no matter what I do I have no display. 

Asked by: Heather L
After pressing the Energy Saving button the display would be turned off. Pressing the button again should reactivate the display and turn off Energy Saving. If this is not the case, please contact our Customer Interactive Center at 800-243-0000 for assistance with this matter.

I just looked at all this and also downloaded the installation instructions and nothing talks about the room venting requirements.  I guess the main question is what is the minimum depth out from the back wall with a cabinet above for a room venting insta

Asked by: McHugh
We appreciate your interest in this over the range microwave oven. Room venting is the default setting for this model. No rear depth is required since the room venting blows through the front of the cabinet. It is for such reasons that this was not listed in the owner’s manual.

Can I install it on the wall (kitchen cabinet) ??

Asked by: Dinorm
2.0 cu.ft. Over-the-Range Microwave Oven with EasyClean®, Model # LMV2031BD can be mounted against a flat, vertical wall, so it is supported by the wall. The wall should be constructed of minimum 2" x 4" wood studding and 3/8" thick drywall or plaster/lath. BE SURE the upper cabinet and rear wall structures can support 150 lbs., plus the weight of any items you place inside the oven or upper cabinet. An installation manual is supplied with the unit that details the minimum distance required between the microwave and the Cooktop surface or Countertop...^IFV
