2.0 cu. ft. Over the Range Microwave Oven with Extenda™ Vent and Warming Lamp

  • LMHM2017SB

  • Smooth Black

Key Features

  • Warming Lamp
  • Extenda™ Vent
  • QuietPower™ Ventilation System
  • Sensor Cooking


LG revolutionizes microwave cooking with the introduction of the first Warming Lamp. The LG Warming Lamp is an additional heating feature using a radiant heating element to keep food warm. Plus you can put any type of cookware under the Warming Lamp.



Over the Range microwaves have always been great at capturing the smoke from the back burners of your stovetop, but not the front burners. LG introduces the Extenda™ Vent, which covers the entire cooking surface allowing for even greater ventilation.

QuietPower™ Ventilation System

QuietPower™ Ventilation System

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.

What People Are Saying

Rated 3 out of 5 by from Dead after 3 Years and 2 Months Purchased the LMHM2017 in Nov. 2011 and absolutely loved this microwave. Used 90% of the cook settings. Popcorn setting was on the money. The Extend-A-Vent was very useful when foods were burned on the underlying gas range to quickly dissipate smoke. However, the microwave did not last for a reasonable amount of time. It died in January 2015 so I'm out hunting a replacement. If LG had not reduced the height and location of the viewing window, I would consider another LG to match my 2011 LG appliances. lose on this one! Will purchase another brand where I can see what's over-cooking. What on earth were you thinking? Listen to the women who use these appliances.....please.

Rated 5 out of 5 by from The microwave has awesome features The microwave is really easy to use and we like the shelving in it for ease of use in heating up multiple items. I like the under lights as well as the exhaust fan for they are are a real nice added feature.

Rated 5 out of 5 by from Great Microwave We have been using this MW for about six months and have been very impressed with overall results and some of the special features. Reheat, warming, and extended exhaust are all great features.

Rated 4 out of 5 by from Cosmetic problem I can't solve The film that covers the control buttons has unsightly bubbles that I have tried to smooth to no avail. Microwave works great, is quiet and without these bubbles would be fantastic.

Rated 4 out of 5 by from Built better than I thought I bought this microwave twice. My grandson was using the microwave as a timer for the oven when it's timer failed. He was operating the microwave with nothing in it for several weeks before it finally failed as well. Most microwaves would have failed much sooner operating with nothing in it. The controls and features are great and it has good looks. A bit pricey but it seems well worth every penny.

Rated 5 out of 5 by from A great product!!! We bought the Lg Microwave to replace a 3 year old, Top Of The Line, microwave that quit working. We loved all of the features on the display model, at Home Depot, and loved them even more once we started using it. The best feature we like is the extended vent. We have a large counter top stove and we needed the extra vent space. We highly recommend this LG Microwave to anyone looking for a replacement.

Rated 5 out of 5 by from Dependable I have had this for several years. I like everything about it, mostly that it is still working. This is the third microwave in 9 years. The others were not LG and just quit after about 2 years. It is same size on outside as others, but the inside is very large. It does all types of things as well. Melt chocolate and butter for one. You will enjoy this product

Rated 4 out of 5 by from 3rd Times A Charm We purchased this microwave to replace an older microwave, so size was important. The first unit we received had a faulty sliding exhaust fan (it would pop open when ever we opened the door, or sometimes just on it's own). That unit was replaced with one that apparently had a bent motor shaft. We were told that was fixable but they would have to dismantle the entire unit, so we opted to just have that replaced as well. As stated above, the 3rd times the charm. We've had no issues with this unit at all and love the sleek style and power that is has. I also love the slide out exhaust fan. It gets to my front burners much better. We are quite happy now.
