I have a Panasonic microwave that just stopped working, no power to the unit at all. I opened it up and took the 20 AMP 120 volt fuse out, and then put it back in, the same fuse... and it started to work again. After 1 day, it stopped working again. If I pull the fuse out and out it back in, it works. Would this be a fuse issue, or something further.
