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.

*Based on manufacturers’ published specifications of over-the-range microwaves as of December, 2013.

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.

Senses Optimal Temperature for Fast Results

Senses Optimal Temperature for Fast Results

Sensor Cooking technology senses humidity levels within the oven and automatically adjusts cooking time and performance to help provide optimal heating performance.


What People Are Saying

Rated 5 out of 5 by from All the bells & whistles and so easy to install. This was a replacement for an older microwave, so we didn't need to install the mounting plate that was included, but used the old one from the previous mw. My husband and I installed it in about 10 minutes. We love it and all the easy preset buttons, especially the "Add 30" or the "+/-" buttons to easily add a little time.

Rated 3 out of 5 by from Don't think would buy again... Purchased as part of kitchen renovation with 4 LG appliances, had about 6 months. At 5'2", I cannot see inside the microwave, even on my toes. When the microwave has stopped, there is a sound, but no further reminder beep/sound in case you're out of room or forget (which is my problem!) so we'll find something in there hours later. Way too may options for cooking, etc. - could be simpler. The lighted display area hasn't worked from day one - don't know what setting is on for fan, light, etc.

Rated 4 out of 5 by from Love the pop out vent hood!! Great product - the only issue is that it is louder than our old microwave. This takes a bit of getting use too!

Rated 4 out of 5 by from A four because of the door. Originally my wife and I bought the model with the control panel across the bottom. The exhaust fan was too loud, and my wife refused to use the microwave. Upon further researching she found that this model, although it has the same features, it also had a quite technology package, and appeared to have a different heavier, and superior door. We replaced the microwave we wanted with the microwave that we believe will do. This made the difference in the fan noise, however, the model we got had the same lightweight door. Hence 4 for the door. One comment about the request for a review; in our case we purchased the product, but I see by your email request for a review that you do not require a person to have purchased the product to review it. I don't know how that would work.

Rated 5 out of 5 by from Love it I bought this to replace an older unit from a different company. I love how big it is inside. I really love the expandable exhaust fan to be able to cover the whole stove when cooking on the front burners. Then is just tucks away. Nice.

Rated 5 out of 5 by from Very Spacious This microwave is awesome. It has so much space inside. Plus the dark interior is excellent because white interior seems to stain and become an eyesore. Great choice and you will not be sorry.

Hi, I moved into a place with an LG LMH2235st. What is the wire rack for? I was always taught never to put meta in a microwave. 

Asked by: DougSaylor
The metal rack gives you extra space when cooking in more than one container at the same time. The rack MUST NOT touch the metal walls or back of the microwave oven. To avoid risk of property damage: Do not use the rack to pop popcorn. The rack must be on the four plastic supports when used. Use the rack only when cooking food on the rack position. Do not cook with the rack on the floor of the oven. ^CP

The slide out fan will not push back in. How do you fix?

Asked by: leiky
If you are referring to the ExtendaVent, please be sure the filter has not become displaced and is stopping the return. IF that is not the cause, you may need service. Please give us a ring at 1-800-243-0000. ^AC
