Any repair on a door or door latch mechanism needs to be accompanied with a microwave leak test. So you'll have to buy a microwave leakage meter first. I'd suggest you find an exploded parts view of the oven for a hint on how to get it back together. If it came apart on its own, though, there's a good chance something is broken in the mechanism.
