My Sharp R1874 Micro/Conv. quit while cooking. Found blown
monitor fuse. Replaced couple times, but continues to blow
immediately when hit Start, without running even short time.
Informed bad magnetron. Have new part but hesitate to install,
as have "gut feel" problem is something other, like HV capacitor,
etc. Recommed giving the new magnetron a try, or risky and may
immediately damage it? Appreciate any help. Larry
