No intention to burst your bubble, and my info my be out of date, but I used to hold a FCC General Radiotelephone License with a Ship's Radar Endorsement...unless they made changes I don't know about don't you need to hold a class II technician's license to repair microwave ovens? Furthermore do you have a meter that checks for microwave leakage? Given the fact that you jury-rigged the door locking mechanism if the seal is not good you may be leaking microwave energy and that's not good at all...dunno what type of computer engineering schooling you're referring to, so if you already know all of this please feel free to ignore me...
