Fuse blowing continually after door slam

My daughter slammed the door to the microwave, but not much harder than the kids usually do. Then it would not come on at all. I did some research on the forum and found the fuse and replaced it. The lights came on and all seemed well. I could open the door and the inside light came on. But when I put something in it and started to microwave it the fuse blows in just a few seconds. I checked what I could of the board the fuse is on and the switches (seems to be three) where the door connects. I don’t see anything odd, but I don’t really know what I am looking for.

I am expecting a switch or two needs to be replaced. But I am not that great with a volt/ohm meter and am not sure how to even check them. I don’t want to order all the switches if I only need one… or if that is not really the problem.

Is there a chance this is something else? Can you give easy directions on how to test the switches to determine which one(s) are shot? Are there other things I should look for?

Thanks for the help.
