The magnetron wave guide had a hole burnt through it, caused by a food particle that was left from a food pop.
It seemed like a serious problem, but is rather common.
Although the sharp Micro wave was not listed on the Part select site, I entered the Model number, it brought up the avaiable parts for it, and was in stock.
Order and delivered with in 7 days very impressive,disconnected powercord, a minute to to pry loose and remove old wave guide, a minute to clean, and 45 seconds to align and install.
Added to my favorites list.
