My black stainless microwave came with scratches, how can this be fixed? 

Asked by: cherrywaffles
We hate to hear that the unit came with scratches. Unfortunately, the LG manufacturer's warranty does not cover cosmetic damage to the unit. It would be suggested to contact the retailer from where it was purchased for further assistance.

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?

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.

This is a question for your kitchen installer. The typical cabinets are set at around 18 inches above the counter, so your microwave should also be about this height above the stove top.
