I do not have the info you are asking about but might throw in some thought on the project as it seems very unlikey a switch sticking would cause the fuse to blow.
The door switch can only connect or disconnect the two wires together so sticking would only make it stay on rather than blow a fuse.
The door switch itself only acts to let the rest of the system work, so it can only be good and things work or bad and the rest doesn't work.
Have you taken the microwave out of the cabinetand removed the coverto look at the rest of the parts?
If the switch tests good, I would expect the problem to be in other parts of the microwave, not the switch. It sounds like there may be an intermitant problem which was jarred and moved a bit while you were working on the switch so that it clears for a time but has now settled into the bad spot again. I might want to look for wires or connections which are making contact at some point.
When the fuse blows can be a clue at times, so do some thinking about when it happens. Is it just as the door closes, just as you turn one part of the operation on like the micro part or only the convection part?
If you can sort it down to blowing the fuse only when one specific item turns on, that can cut the chase onlooking for the fault. The micro will have seperate portions which operate at different times as controled by the control panel, so so deciding which of those sections causes it to fail can be helpful.
Unfortunatly, one of the more common failures is the board and that is often more expensive to replace than buying a new microwave!
Wish you luck on the project!
