Rated 5 out of 5 by from Great functioning microwave! I researched microwaves that had the functions of my 12 year old appliance that eventually broke. This product was affordable, the features were perfect for what I needed and it looks great! The only downside is that you need to press buttons a bit harder.

Rated 5 out of 5 by from Nice Micro At first was overwhelmed with the options already set up in the program for this micro, but after just a couple of weeks it is easy to use. The style is so nice and is the final piece to my complete LG kitchen.

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.

Simpliest way to heat a cup of coffee?

Installed our new LMV1683 a couple days ago and are having trouble following instructions on how to use it for the simple things like heating a cup of coffee. Either I am getting old and can't follow directions or your owner's manual is hard to follow. Most of the things I will never use but to quickly heat a cup of coffee is something I will use a number of times each day. HELP! Thank you. TomE
Asked by: TomEnglish
The simplest method for reheating liquids would likely be the TEA category for the SENSOR REHEAT function. It is recommended to place the cup in the microwave, then press the REHEAT button, then the #6, and then the START/ENTER button. Stir the liquid when the unit beeps and displays END. This information can be found on page 15 of your owner’s manual.
