Microwave fuse repair

I have no power on my microwave but the electric breaker in the house is fine. I beleive an internal fuse may have blown. The part is cheap enough but is this an easy repair? I have the mfg’s part diagram and it looks easy eonught but I dont want to start something I can’t finish. Can I get assitance by phone or online prior to purchasing the part?

Gene, thanks for your reply. What else could be wrong with it? How simple is removing the grill and control panel? Is it worth the small investment in the fuse and my own labor? thanks, Simon
