What People Are Saying

Rated 5 out of 5 by from Works great and easy to use. Over a months use and no complaints, auto reheat is one of many excellent features.

Rated 5 out of 5 by from Love this microwave Bought this a couple months ago. It's nice and quiet when it's running. Love the soften & melt features. The popcorn button works perfectly. Only improvement we could suggest is a quieter operating fan.

Rated 3 out of 5 by from We loved this appliance, but unfortunately it died after two years and three months. We just purchased the same one with hopes for a better life. I think that we should buy the extended warranty.

Rated 5 out of 5 by from Love the grey Interior We have been using this microwave for about 6 weeks and love eveything about it, especially the grey interior which looks sleek and very easy to keep clean

Rated 4 out of 5 by from Good product. I bought this MW over a month ago. I'm happy with it with the exception of the control panel. The buttons are much harder to push than they should be.

Rated 4 out of 5 by from Had this for a few weeks. So far it has been great. Nice features.

Rated 2 out of 5 by from Poor Quality It was great up until right after the 1 year warranty. It begun to let you only use it to heat for example 1 Hot Pocket and then you would have to wait a while to be able to use it again. About a month later it quit heating altogether.
Date published: 2016-11-14
Rated 1 out of 5 by from Poor Quality You are only able to use it to heat or cook one item and then it won't work for several hours. I have had it just over a year and it has completely stopped working.

Bought LMV1831ST, worked great for 1 1/2 years till yesterday, then today the power was off.  Nothing suspicious noticed. I thought it would be a fuse problem, till I read a previous answer saying there's no fuse in this model. What to do next?

The microwave is running but not hearing.  This is the second time and the first time we just kept hitting buttons and it finally worked.  Is there a combination of buttons to push to reset.  

Asked by: WandaEf
We regret the trouble you have experienced with this microwave oven. The control panel on this model does not have the option of activating or deactivating the audible signals. If the sound is out, then the unit will likely require service. To make service arrangements, you may either contact our Customer Interactive Center at 800-243-0000, or you can check our Repair Provider Lookup on our website, at http://www.lg.com/us/support/repair/support-repair-provider-lookup.jsp.

What is the bi level shelf used for and can it stay in microwave at all times?

Asked by: Debbie56
We appreciate your interest in this microwave oven and its accessories. This shelf can be used for items that are too long to rotate with the turn table. Yes, the shelf can stay in, unless it is in the way of the items being cooked.

Can this microwave be placed into a cupboard?

I am remodeling my kitchen. I want to move the microwave either into a wall above a double wall oven (see pic), or into a center island (see second pic). Are either possible? I obviously wouldn't be using the fan option any longer, but is there any danger with installing them in these two locations without venting?
Asked by: tdtchr
We appreciate your interest in this microwave oven. This model is designed specifically for an Over-the-Range installation. Using the installation options mentioned will negatively affect the operations of this microwave oven, and is not recommended.
