LMV1831SB 30" 1.8 cu. ft. Over-the-Range Microwave with 1000 Watt Cooking Power, Sensor Cooking Controls, EasyClean, Child Lock, Hidden Vent and Auto-defrost, in Black is rated 4.58 out of 5 by 50.
Rated 5 out of 5 by from I like the clean stying. Matches LG refrigerator Installation may be complicated. Width is 30 inches, but 30-1/2 is needed when door is open, which may conflict with adjacent cabinet or wall. Also, top mounting bolt holes are 10-3/8 from back wall, which may conflict with top cabinet mounting, especially if modification was needed to accommodate the door opening issue. I had to extend out the wall mounting by 1 inch to allow door opening this made the top bolt mounting conflict with the top cabinet depth. An aluminum plate was added and was secured to m-wave mounting holes. Additional holes in plate closer to back wall were tapped to secure to top cabinet.

Rated 5 out of 5 by from First choice microwave We purchased this microwave as part of an appliance upgrade simply to have matching appliances, were we surprised. We were happy with our old microwave but this unit is simply way superior, even to reheating pizza, its in a class of its own. We make a lot of use of a microwave, cooking vegetables, oatmeal and sauces virtually every day - this product excelled in every way. Our greatest satisfaction is with the vent fan, its a lot quieter than its predecessor and way more efficient but make sure you get your installer to vent to the outside atmosphere, a kitchen with no smells is possible with this unit.

Rated 5 out of 5 by from Simple but surprising! I do a lot of baking, so I do a lot butter melting, chocolate melting, all kinds of melting. This microwave is perfect for all this! Our old microwave would make the butter start spattering after just a few seconds. This microwave melts anything without that, therefore not creating a mess! I definitely like the rack in the microwave so you can warm up two plates/bowls of food at the same time. I have had no issues with this microwave and honestly was pleasantly surprised at how it seems to warm everything perfectly.

Rated 5 out of 5 by from Super quiet Our new microwave is super quiet compared to our old one. It has fairly standard features that all work well. Our old one had a 1 minute button, this one only has a 30 second button. You just press it twice for a minute. I thought I would hate that but it is actually better. It has a shelf that we have never used but it is removable. Good basic microwave for the price.

Rated 5 out of 5 by from my wife loves this microwave I am very happy that I purchased this particular microwave. It looks great, has all the features I was looking for and my wife is happy with this model. She says she really likes the one touch reheat preset function. For example, when she reheats pancakes she says they are not soggy or hard. I found my microwave at best buy for a great price.

Rated 5 out of 5 by from Love the features This microwave has this "sensor" feature. So for something like "dinner plate" or "pizza" you just put the food in, find the corresponding number and let it go. No programming of minutes or power level or anything. Every time I've used it it's warmed the food all the way through and it comes out perfect. Thanks LG!

Rated 5 out of 5 by from Love my new microwave! As others have said, the microwave looks great, is easy to use and has some great features I haven't seen on other microwaves - soften and melt, auto timeset. The only feature that needs improvement is the over the stove light - it is way too dim and disappointing in a product that is otherwise so great.
Date published: 2014-09-19
Rated 5 out of 5 by from Quality built, quiet and easy to use. LG has the best over the range microwave. It is good looking, quiet and easy to use. The fan moves air out of the kitchen and built in lights put the shine on the stove top. Having owned LG products in he past, I know I can count on LG to give great service over the years trouble free. Paul Engell
