Broken Toshiba Microwave (NW Austin (near 360 and 2222))

This microwave is in great condition, just out of warranty, and decided to stop working.
It seems like it's related to the door sensor; before it died completely, for a few weeks it was occasionally turning the fan and turntable on while the door was open (but not microwaving - we tested w/glass of water).
But now it won't start when pressing Start, etc.
We already replaced it with a new one (the exact same model -- in the picture, that's the box the new one came in!).
This feels like it might be easy for someone handy to fix and keep or resell! Please come and get it!
