about 1 in 5 times when I open the door, all power goes out to the unit. Anywhere from 1-5 minutes later it comes back on and I can use the microwave. It only seems to happen when I open the door. If I leave it open and let the fuse grow back or reset or whatever I can close the door and use it.

I've been doing some searching and reading about interlocks and switches, but I have no idea if that's what I need or which parts to order if indeed I do need them.

It's a revision - 0 after that model number if it makes a difference.

Thanks in advance!
