Rated 5 out of 5 by The features designed are great I researched the microwave ranges and found this one had all the features we wanted. The design really had the user/customer in mind. It's easy to use and clean. The pricing was well in the price range we were looking for. The installation was very easy. You really don't know it's on, it's so quiet June 14, 2014
Rated 5 out of 5 by So many features This microwave is great. I love the soften butter button along with the defrost button that works better than any other microwave I have ever owned May 25, 2014
Rated 5 out of 5 by Great Value We love it. It looks great in our new revonated kitchen. It complements the matching range and works great. May 11, 2014
Rated 5 out of 5 by 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 April 23, 2014
Rated 5 out of 5 by Simple to operate Coffee at 1 min comes out hotter than a previous microwave of the same power. April 12, 2014

My last LG microwave vented outside while I was cooking in the microwave. The flap opened out and you could smell what ever I was cooking in my microwave outside. I have found other brands are so slow while cooking that the flap does not open on the outside vent. I feel the heat under the microwave and there is condensation on the front outside door by the time it is finished cooking in the microwave. This is a brand new microwave.

Hello Pookie,
Congratulations on your new LG LMV1813ST 1.8 cu.ft. Over-The-Range Microwave.
Like you last microwave, so too will this unit vent because while you're cooking, it is normal for steam to be produced and the microwave is designed to vent the steam out through the top...IFV

It built to recirculate the air out the top, but can it be converted to vent out the back through vent in wall to outside?
