Query: Cool factor great, but door won't open

This microwave came with our new house which we bought almost 1 year ago. Everyone thinks it is so cool because of how the door slides out. It's worked fine since we got it, but nothing special (Certainly our previous $100 microwave was sufficient for our needs). After less than a year of use, the door doesn't open anymore, and repairing it will be over $400! It needs two control panels replaced. The home builder purchased it a year and a half ago, so no warranty.
