suddenly no power at all?

I have a 1999 Sanyo microwave that was working fine then about an hour after I last used it, I went to use it again only there was NO POWER to it at all. I thought maybe unplugged or something, but everything else works fine still. Just NOT the microwave at all. Is there a fuse in the micro that maybe needs to b replaced? Any help would b appreciated! Thank you in advance!
