Clear the Air

Say goodbye to smoke and lingering cooking smells and hello to LG’s enhanced ExtendaVent™. Where most over-the-range microwaves only cover the rear of the cooktop, 2nd Generation Slide-out ExtendaVent™ provides powerful ventilation over the entire cooktop, back to front. That’s what we call clearing the air.


Don't Sweat the Splatters

Spills? Splatters? Don’t sweat it. LG’s EasyClean® interior resists stains and buildup, so cleaning your microwave doesn’t have to be a chore. Simply wipe with a damp cloth—no chemicals, no scrubbing, no problem.


Save Your Energy

LG's Energy Savings feature turns off the display when it has been inactive for 5 minutes. This feature saves energy by dropping the overall power consumption to less than 0.1W.


Largest Capacity*

With the 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 January 2014


Perfectly Cooked Meals

Sensor cooking technology measures humidity levels inside the oven to automatically adjust cooking time and power for deliciously perfect results.


Premium, Stylish Design

Why choose between style and power? LG's premium stainless steel finish brings elegance and clean lines to your over-the-range microwave and beauty to your kitchen.


What People Are Saying

Rated 5 out of 5 by from This unit exhausts the entire cook top I bought this microwave 2 weeks ago. It arrived and we installed it. The six sensor controls on the right did not work. The unit would run 15 seconds and cut off with a F-4 warning. I booked a repair through the LG site(extremely easy) but I was not happy that a brand new machine was not working. The repairman arrived the next day and the humidity sensor was unplugged. The repairman was in and out in 10 minutes. Shipping had jarred it loose. (the plug in fitting was not pushed in tight enough). I am totally impressed with the machine but moreso with their excellent repair network.

Rated 4 out of 5 by from Great product for my application I purchased this microwave approximately 4 weeks ago to replace another LG that was over 10 years old and still working. The only problem we had with the previous one was the fan was not drawing the steam up the vent. With this extendavent system the steam is now moving up the vent. I do have a couple of issues that LG should consider to make this product even better. 1. Improve the inside lighting 2. Change the interior colour to white for improved visibility when looking through the glass 3. Give the option of having the clock on permanently.

Rated 4 out of 5 by from Extendavent We have a cooktop stove and were having issues with the steam from the front 2 burners not exhausting completely. This was the only manufacturer that had this feature and I must say it is doing exactly what we wanted from a OTR microwave. The only issue I have with this product is the size of the readout of the clock and the fact that this clock only stays on for 5 minutes. It has an energy saving button but it does not do what it claims to do in the manual.....what's up with that LG ???

Rated 4 out of 5 by from Great Features but Fan could use more power Great product. Features work great. Sensor re-heating is no better or worse than the competition. Cons: Exhaust suction power. Not sure if it is exhaust motor or the poorly made filters but suction power don't seem enough if you have more than one pot on the stove at boiling point.

Rated 5 out of 5 by from quality the LG LMV2257ST microwave. The microwave is such a powerful, useful tool in the kitchen I use it for something just about every time I prepare a meal. Whether it is for defrosting, holding food warm, or actually cooking an item. The sensor cook technology is out of this world! I can press the button and walk away and not have to worry about checking my food every few minutes to make sure the food is not turning to rubber. The ventilation system is top notch...
