Don't buy LG - just don't do it.... You WILL regret it. I know, every company has failures, and you can find a person who hates any company. But, LG is horrid. This is the second microwave from them that failed with the same problem - in the original warranty period!
After months of fighting with them, they finally replaced the original unit, and now the new one is dead! Called them up and they start giving excuses for not replacing the second one. I will buy a new microwave - I just don't have the energy to fight them anymore and even if I win, can't go another 3 months without a microwave...
It doesn't matter how cheap LG are, there is a reason they are cheap... Don't fool your self - you'll spend less if pay more.
