Someone gave me a twenty-year old Sharp Carousel in cosmetically perfect condition. The inside even smells new. The AC stuff and bells and whistles are working. The turntable coupler (very tiny plastic square plug that sits exactly center and connects the glass turntable and turntable spindle to the underbelly...allowing the glass to rotate) is broken. A replacement sells online for $10 shipped. I searched to see if microwaves are worth repairing but couldn't find anything, so I thought I'd post here.
Would a broken $10 coupler indicate problems with the microwave that can't be seen? Thanks.
