What People Are Saying

Rated 4 out of 5 by from Great microwave with convection to boot! Recently bought this and very pleased thus far. It takes some studying to understand all the features and cooking options. Haven’t tried the convection method as yet.

Rated 4 out of 5 by from Versatile convection and microwave Bought b/c lg was highly rated in microwaves. Like the seamless body inside and the turn knob vs number pad.

Rated 3 out of 5 by from Having some issues We bought 2. Both havibg issuea after 1 month. Waiting on tech to check it. One is giving us an erreor mesaage and wont work at all. The other will sometimes work, and other times you press what you want and it doesn't turn on. After a few tries of pushing the exact same buttons itll usually work :(

Rated 4 out of 5 by from Overall very good so far, but needs improvement. Could use a quick, one button beverage warm up or just say a one button 60 or 90 second Microwavexon High button. Sensor feature seems to work well.

Rated 5 out of 5 by from Love it! We had our kitchen remodeled and selected the LG over the store studio microwave. The remodelers connected our microwave right after the cabinets were installed but not our new LG stove for a couple of more weeks. After 3 months of microwave food I was ready to try out the confection bake on the microwave. Wow, it works great. First thing I bake were cinnamon rolls, came out perfect! Browned just right.

Rated 4 out of 5 by from I bought this last month and I love it! I would give it five stars if it had a low, medium, and high - light function on the bottom. It only has one light function and is NOT fingerprint resistant. It's very hard to keep clean.

Rated 1 out of 5 by from Got a Lemon If you buy this, make sure it is working consistently before the installer leaves. Ours never worked consistently, and now our old microwave is gone, and Costco is telling us it's 2-3 weeks to get a new one.

Rated 3 out of 5 by from Great features, poor fan Purchased this microwave 3 months ago. Works really well, easy to install BUT exhaust fan is the poorest of any previous microwave I have owned. Had it checked by LG repair tech, found was installed correctly, but that is just the way the fan is. Getting plenty of exhaust from unit to outside of building, but it does not come from under the hood. Top, inside? Who knows.

How loud is the exhaust fan?

Asked by: Thedbart
Regrettably, we do not have a decibel rating as that can depend on the install set up of the unit. ^AC

How  do I get it out there f demo mode?

Asked by: Trisystem
Hello, please check to see if you have the option to turn off the feature under the custom set button. If not, you may need to reset the unit by unplugging the unit for 24 hours and plugging it back in. ^AC

I can not vent the exhaust to the outside of the home. Can the exhaust recirculate? My over the range microwaves have had this option in the past but I don't see that it is listed in the specs.

I understand from reviews that the LG display is difficult to see on the microwave model LSMC3086ST. Is that true?

Yes, it is hard to see. You need a bright light overhead. Don't recommend it.
