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 1 out of 5 by from Megatron failure We have multiple appliances in our home. The only product that has been a total disappointment for us is this microwave. The device quit cooking after less than two years of use. This seems to be a frequent problem for LG, as I have read similar complaints

Rated 5 out of 5 by from The preset options are great I bought this microwave as apart of a rage + microwave package. It looks great and I love the extendable fan. I also really enjoy all of the preset options - they make it easy on me because I don't need to figure out how long to heat dinner plates, or melt a stick of butter, etc.

Rated 5 out of 5 by from Excellent Unit I bought this product to replace a 5 year old Frigidaire unit that was of poor quality. The LG is a better quality product with very helpful features. I only wish I bought this one first.

Rated 5 out of 5 by from Works well for our family. Vast improvement from our previous microwave. Lots of great features and easy to use. :)

Rated 5 out of 5 by from Excellent Microwave!!!! We owned several microwaves and we just remodeled our house and installed this over the counter microwave. It's not a decision you want to take easily as it's a focal point. This has to be the best microwave we've every owned. All of the features are awesome including the exhaust fan, bright lights, ease of cleaning and so on. Our last microwave had a hard to open door and this one feels like nothing, which is great! I'd buy it again without hesitation, if I needed another one.

Is this unit designed to vent outside through ductwork?

Asked by: Bronco1
The LG 2.2 cu.ft. Over-the-Range Microwave Oven, Model # LMH2235ST can be vented in one of three ways, Roof-Venting, Wall-Venting or Room Venting. It is shipped with the blower assembled for Roof-Venting and the blower would have to be adjusted for wall-venting or room-venting. The total length of the duct system, including straight duct, elbows, transitions and wall or roof caps must not exceed 140 feet and for the best performance, you should not use more than three elbows...^IFV

Bought 4pc. appliance set. All items work good except the microwave's clock. Set the clock and 5 minutes later, clock goes out. Open the door clock comes on. Close door & 5 min. later clock goes out. I've tried every way to fix problem and nothing works.

purchased LMH2235ST over the range microwave what is the recommended distance for the gap from microwave to stove

Asked by: jv3002
We appreciate your interest in this microwave oven. While there is no listed distance between the bottom of the microwave and the oven, the required gap between the overhead cabinet, to which the microwave mounts, must be 30” above the surface of the range. This will allow for sufficient spacing for the microwave oven.

our upper cabinet depth is 15". What microwave will allow venting out of the front rather than the top?

We recently purchased Model:LMV2031 and the maximum upper cabinet depth is 13" to allow for top room venting. Do you have other models that will room vent when the upper cabinet depth is 15"?
Asked by: PapaW
We appreciate your interest in these LG microwave ovens. It appears that all of our current microwave models are designed to provide room venting, blowing upward, and yet are slightly under the 15” depth

Where to find install instructions

I just purchased a home and bought this microwave. Have not moved in yet and would like to know how to install this. Does it mount to the wall?If so I would like to open the wall and install blocks of wood to mount it,and patch and paint the wall.before I move in.
Asked by: Pipeslinger
It comes with a wall bracket for stabiltiy, but the weight is carried by screws that hold it up from the top. You'd better plan on a cabinet of some sort over the microwave. Mounting instructions are included.
