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.
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
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
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 3 out of
Loved the features but....I have had this unit for almost 4 years now. It broke down just after the 1 year warranty and the repairman had to replace the magnatron. Now about 2 years later we are experiencing the same problem again. I might try to replace this again myself but also might just research and try to find a more reliable microwave.

Want to love it, but....I have had this microwave for 4 months. The front vent means it vents directly onto my cabinet, so I have to wipe my cabinet down just about every use. The door has never latched properly (and yes, I have had service out to look at it) so a lot of the times I have to open and close, and re-open and close to get it to go. I have a nice yellow/orange/brown discoloration on my ceiling now, I assume from the steam and the stain from my cabinet. The vent is LOUD. Like hurts your ears loud. On the positive, it does re-heat well!

What is the height of the actual microwave (NOT including the Extend-a-Vent) that must be mounted on the back wall? Is it 15 3/4"? Also, is the Extend-a-Vent mounted to the bottom of the microwave and NOT the back wall?
Asked by: Basa
The listed height of 17 15/16" for the 2.2 cu. ft. Over-the-Range Microwave Oven with EasyClean®, Model # LMHM2235ST is the actual height of the microwave oven (NOT including the Extend-a-Vent)). The ExtendaVent™ slides out from the bottom of the microwave oven as shown in the thumbnail images that you can view by clicking the last thumbnail image with the "+4" superimposed on it on the product information page on the company site. The sixth and seventh images show the ExtendaVent™ when it is extended. It extends out from the bottom of the microwave so it can cover more of the Cooktop surface of the range oven that is installed under it...^IFV
