Query: don't buy

Stopped working after three months of owning it. The electrical, lights, timer and turntable work. Essentially everything looks like it should be working. But it doesn't heat anything. The only way to get a warranty repair is to pay for shipping both ways. At that price, you might as well buy a brand new microwave. Judging by all the crappy reviews, others are having the same experience. I will never buy a Cuisinart microwave oven again.
