ExtendaVent™ 2.0
Where most over the range microwaves only cover the rear of the cooktop, ExtendaVent™ 2.0 provides powerful ventilation over the entire cooktop, back to front

LG's EasyClean™ interior resists stains and buildup, so cleaning your microwave doesn't have to be a chore, simply wipe with a damp cloth - no chemicals, no scrubbing, no problem

Sensor cook
Eliminate the guesswork in cooking; humidity-sending technology determines when food is cooked and automatically turns off the microwave to help prevent the over or under-cooking of meals

Eco-on feature
Saves energy by turning off the display when not in use; the display will turn off when the unit is not active for 5 minutes; when this feature is in use the power consumption drops to below 0.1 watts

Automatically defrosts for a specified amount of time

1-touch settings
Makes it easy to cook and warm a variety of foods, from a cup of coffee to chicken nuggets

Add time controls

With an Over-the-Range Microwave Oven, strong ventilation is key. That’s why LG has created the QuietPower vent, which does the job quietly, without interrupting your life. 

Reduce smoke and lingering cooking smells with LG’s enhanced ExtendaVent™ 2.0. Where most over-the-range microwaves only cover the rear of the cooktop, ExtendaVent™ 2.0 provides powerful ventilation over virtually the entire cooktop, back to front. That’s what we call clearing the air

LMHM2237ST 30" Over-the-Range Microwave Oven with 2.2 cu. ft., 400 CFM Venting System, Sensor Cooking, EasyClean, ExtendaVent, QuietPower Ventilation System, and 1-touch Settings in Stainless Steel is rated 4.535714285714286 out of 5 by 56.
Rated 5 out of 5 by from GREAT VENTILATION DESIGN I could not be happier with this unit. Was worried that only having one light underneath would not be substantial, but was pleasantly surprised about how bright the one LED light is. The pull out vent is the ultimate design for getting cooking odors out of the house as it pulls foreward to ventilate the front burners of the stove. We enjoy cooking and cook alot and venting out was always a problem with the previous over the range microwave we had. This has a powerful and quiet 4 speed fan that really pulls the smells out of the house. (we vent to outside) Very powerful microwave, cooks much faster than the old one. I highly recomend this unit.

Rated 5 out of 5 by from A Really Great Microwave Bought this microwave in mid-December 2014 and installed it a few days after receiving it above a new double over LG gas stove. I really love the feature that extends the ventilation over a greater surface area of the stove below. The installation instructions were really good and the templates for where to drill holes and how to modify how the microwave vents was excellent. The ventilation fan is powerful but is not noisy. The microwave interior is very nice and it is large. I have nothing negative to say about this LG product. If you get one you will be very happy with it.

Rated 5 out of 5 by from Nice-looking microwave that works well. We are very happy with this microwave. Having the "buttons" on the bottom took a bit of time to get used to, especially for the kids. Interestingly, the fan has turned on automatically every time I have run the self-clean cycle on my LG range and it starts to get hot and smoky - a feature I was not expecting at all! The only thing I don't like about the microwave is the light - I would prefer to have a warm LED bulb rather than the glaring blue-white one. (This is such a minor thing that I haven't even bothered to figure out if I can replace it, so I doubt it would be a deal-breaker for many people.) We get so many compliments on the microwave's appearance - I've recommended it to everyone I know who is considering new appliances.

Rated 4 out of 5 by from Not for short people As far as how it works - it works well. Initially I liked the looks of the selection menu-bar running across the bottom of the front door instead of on the right hand side. I am sorry I bought this model which sits over my range. I am 5-4" tall and cannot see into it while it is cooking. Items boil over because I cannot see into it, due to a dark panel inside the glass door at bottom. It is also very hard to keep clean on the outside, black/stainless and we are just two adults here, no kids. I would not buy this again and it was expensive.

Rated 5 out of 5 by from SUPER MICROWAVE We've owned quite a few microwave's since there invention. This one however stands out amongst the rest. I have never owned one that is so quite. It does a fantastic job. It's extremely easy to use and has outstanding features. We've owned this microwave about 3 months now and love it. Kudo's to LG for coming up with such a fantastic product. We are so impressed that we recently bought an LG refrigerator. We'll review it once we've owned it for a while.

Rated 4 out of 5 by from Great microwave! I bought this unit 1 week ago , but installed today. Everything about this unit is great with the exception of one feature . It looks very classy , cooks great , but the unit has an automatic energy saver built in which causes the clock to vanish after 5 min. I know I bought a microwave but if you are going to put a clock on it , you should be able to tell what time it is at any time of day .

Rated 5 out of 5 by from Most Definately Satisfied I absolutely LOVE my LG microwave!! It does so many things, and does them so well. My favorite feature is the extending exhaust fan. This has been a nice feature for quick removal of baking and cooking heat, especially during the summer in Florida temperatures. All my new LG applicances have been amazing and the best I ever owned. I highly recommend LG products. Very quality products!

Rated 5 out of 5 by from Many choices to cook any dish I had a different brand for 5 years and just recently replaced with the LG. The light and fan is a huge improvement as well as all the various options for cooking. The bacon comes out just the way I like (crispy and well done) Vegetables are cooked to the right degree of doneness. All in all a great product and am sure we will have many meals from this great microwave.
