Happy Thanksgiving week to everyone out there ! Our 2006 2700 microwave trim kit (the metal surround holding it in place ) had been developing cracks in the inside corners for a few years now. During the last
couple years the cracks had been growing to the point where the lower right corner had only a 1/4 inch left to being all the way through.
I contacted the factory, and was told that part had been discontinued years ago. After being given the part no, which now escapes me, I did an on-line search and found nothing.
The metal is thin, and a welder told me welding would be sketchy at best.
I decided to try epoxiing in 2" "L" metal brackets in each corner, front and back, 8 in all, with J B Weld.
I sanded to metal all the corners first, and applied the epoxy liberally enough to use as "filler" for the edges of the brackets, which I sanded smooth after curing.
After sanding, I repainted the whole thing with Rustoleum cream colored spray paint. The "Crinkle" style, to match what's there.
I must say it turned out better than I expected ! The repair is almost invisible.
That was this spring before travelling, and it has held up 5,000 miles later with no trace of re-cracking.
If anyone has an older PC with the Sharp microwave, and cracks starting in a similar fashion, I can recomend this fix.
