Query: Grrrr!!!!!

I just purchased this microwave a couple of months ago to replace an old one that we had that still worked, but, was just OLD. Well, this new "wonderful" one just stopped working. It spins, lights up and seems to be working but doesn't heat anything. I can't find any documentation that might have came with it and of course, we tossed the box the week we got it. Grrr!!! So annoying! Will NEVER buy another Emerson product!
