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.

Rated 5 out of 5 by from Excellent microwave oen I bought this over-the-range microwave about a month ago. I had it professionally installed. It is very easy to use and very powerful. I like the easy clean interior and the extendable exhaust drawer that draws in all of the heat and smoke from our range. The controls are very easy to use. LG did a great job in designing and manufacturing this oven.

Rated 5 out of 5 by from Great Buy! Very nice looking microwave. So far very easy to use. Still figuring things out. Nothing like my old one, so taking time to get used to finger pressure, short cuts everything seems to be different. Not in a bad way. Would recommend.

Rated 5 out of 5 by from Great OTR Microwave I bought this LG Microwave a little over a month ago to match an oven that I bought. It is the easiest and nicest microwave that I have ever owned. This unit has a great “Extendavent” feature that expands the vented area. This has been great for sucking up all the steam and smoke from my frying pans on the front burners. Also has great lighting and large interior space for big platters.

Rated 3 out of 5 by from looks good there was only one thing I don't like about this microwave. We installed it over the stove, of coarse it has that great slide out fan, but I cannot see into it when something is cooking. At first I thought there was no light but if I stand on my tippy toes I can see. There is a black out around the inside of the door so you cannot see until you are about 6 inches up. I am only 5'4 but that is probably about average for woman.
