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.

What People Are Saying

Rated 5 out of 5 by from extendable vent and variety of options I absolutely LOVE my microwave. We have had it for over 6 months and there are no complaints. We are always using the extendable bottom vent and it comes in handy when cooking pasta on the front two larger eyes. I also am constantly using the different cooking options. I never cook baked potatoes in the over any longer. This is a great buy and we got a really good deal at Lowe's. We did have to take the first one back to Lowes - when we opened the box the vent was broken. But they immediately took care of us and even offered to deliver the new one to our home for the inconvenience when it came in. Great microwave - highly recommended

Rated 5 out of 5 by from Quiet and easy to use. This LG microwave has met and exceeded previous owned microwaves for ease of use, sound level and features that we mostly use. The soften and melt and reheat features have surprised us with how well they work compared to other microwaves we have owned.

Rated 5 out of 5 by from Gorgeous look!! We've had our new black stainless microwave for about a month. Absolutely love the look, the performance and just overall it's great. Waiting on the entire appliance package to be delivered. That's the only thing I can complain about is the length of time Lowes is taking to get it to us. The black stainless is so popular so I suppose that is the reason. Can't wait to review the rest. If they perform as well as the microwave we will be good. Love LG products as we have TVS and washing machine and dryer too.

How do you keep the clock display on permanently? It vanishes after about 5 minutes.

Asked by: Jsann
We appreciate your interest in this microwave oven. According to the information in the owner’s manual, the display will automatically turn off after 5 minutes of idleness, depending upon the model. Otherwise, press the CUSTOM SET button, press 2 for CLOCK ON/OFF, and then press 1 for the CLOCK ON selection. If this option is not available, then this will remain as default operation.

What is the rear vent size 

Asked by: Nwood
LG Black Stainless Steel Series 2.2 cu.ft. Over-the-Range Microwave Oven, Model # LMHM2237BD does not have a rear vent. It has an Auto Vent Feature which is an automatic vent fan operation that helps to dissipate heat from your cooktop. When the microwave oven senses an increase in the temperature from the cooktop below, it will automatically turn on the vent fan to create a safer environment for you. During this operation, the scrolling test display on the oven will caution you that the surface beneath is hot by scrolling "Caution Hot Surface". The vent fan cannot be manually shut off during the Auto Vent operation, it will automatically shut off once it determines that the area beneath it has reached a safe temperature...^IFV
