Flawless new finish lets your style shine.

Deep yet brilliantly appealing, LG Black Stainless Steel Series brings an undeniable luster to kitchens. It elevates the traditional stainless steel look that's become the standard in today's homes with a satin-smooth, warm and sophisticated finish—a timeless expression that pairs beautifully with any style or color.

Catch The Smoke

Catch The Smoke

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.



With the new EasyClean® interior, you can have quick and high performance cleaning inside and out without using chemicals.

Largest Capacity*

Largest Capacity*

With largest capacity at 2.2. cu.ft., there's always plenty of room to heat large items.

What People Are Saying

Rated 4 out of 5 by from Love the slide out hood. This is my 2nd LG, over the range microwave with the slide out hood. I enjoyed my previous microwave and I was surprised when it went out. It just stopped working. It was purchased Jan 12, 2012 and my maintenance contract with Sears ended Jan 12, 2017. I expected the life expectancy to be longer and I guess I could have tried to get it fixed but I estimated the cost for a service order, time it would be down if we had to order parts and the cost of the parts, I may just want to get a newer one. I checked several retailers for my LG microwave with the extended hood and found not all the stores carried this model, I checked several stores, I found one store but they did not install. I had to keep searching and was happy to find it and they offered installation. I like the new microwave so far but question, why the programs was placed on the door and not on the side as previous designs. Having the program on the door makes it harder to look inside and check your dish as it is being cooked. Considering this is over the range microwave, the height to view inside is very inconvenient and with the program on the door to which it covers about 1/4 view of the glass door, in my opinion is a poor design of the microwave. On the side of the handle is wasted, unserviceable, functional space. I just had the microwave installed today and hope it is as great as my previous LG microwave. Look forward to using it and happy to have it.

Rated 2 out of 5 by from We installed our new microwave about 3 weeks ago. The microwave is large but very nice looking. The extend a vent does appear to make the unit larger than most. As other reviewers have mentioned the extend a vent is painted white plastic and seems to chip very easily. After only 3 weeks have noticed our first white plastic spot. This is very concerning as to what the microwave might look like after a few years. We also have an issue with the display not working correctly when the fan is on. Not a huge problem but does have us concerned if there is a larger issue with the electronics on our unit. Overall, to be very honest, we think the quality of the product for this price point is not good when you consider the issues with the extend a vent and display. We've also noticed that the center of the food is still frozen while the rest is very hot when following heating instructions on the food...we just heat the food for 30-40 seconds longer. In addition, for our personal taste, the microwave looks too big for our kitchen. Overall I hope to return it and would not recommend the product.

Rated 5 out of 5 by from Features, Features, Features! My wife and I purchased this appliance two months ago with a stainless steel door-in-door refrigerator and matching range. It looks amazing with our cherry cabinets. The microwave is touch screen technology. The touch screen is highly responsive with the slightest fingertip touch. Be sure your fingers are not oily, sticky or encrusted with flour, or, you will be wiping down the screen of the microwave often. The underside lighting provides enough light to cook on the stove. The fan is powerful and relatively quiet. This microwave has a pop out screen on the underside that pulls out to cover the entire cooking surface of the stove. No more steam or cooking oil rising up to the overhead cabinets. YEAH! This microwave offers multiple selections for warming/heating/cooking a variety of foods using the touchscreen menu to select the food type. No more guessing on minutes and seconds to prepare food such as leftover meals, pasta, casseroles, or soup. I am amazed at the features of this artistically appearing appliance. This appliance has contributed to giving my kitchen a "remodeled" look at a fraction of the price. My wife and I highly recommend this appliance.

Rated 5 out of 5 by from We have purchased it few months ago and it is looking and working great. I have changed the vent from inside circulation to vent-out. Venting out very well.

Rated 3 out of 5 by from Nice features a few problems Liked the looks of the LMHM2237ST and the extend a vent. Replacing an existing microwave so opted to put it in with help. A minor problem is that the wall and cabinet templates have to be trimmed before use and when lined up with the center line on the wall you quickly find out they are not 100% to scale when you place the wall bracket over it. Allowed for that and microwave went up on first try. A bigger problem is when stainless steel is not stainless steel but very cheaply painted white plastic. The door and trim are metal, but the front of the extend a vent is not. As soon as I took off the protective plastic, a small bump with a light brush turned into a white plastic spot. I have no problem with well constructed chromed plastic, but for something that needs to be frequently cleaned for grease, this is very poor. Due to an upcoming trip I will not be able to talk customer support for a couple weeks, but will be surprised if it gets covered and will be too late to take down and return to the store. Chip is on right on bottom vent piece in attached picture. Microwave and vent system itself works well.

We're remodeling our kitchen. The cabinets will not be ready for a few weeks. Can we use this microwave on a countertop in the meantime? Will there be any problems with the ventilation?

Asked by: Ronald1956
We appreciate your interest in this microwave oven. It is not recommended to operate this device while it is on a countertop surface. The circulating fan draws air from under the microwave cabinet.
