Viking brand is very proud (expensive) of any and all of their repair parts. I removed the convection oven fan that quit working, disassembled it, and figured out I needed a new Fan/Flower Motor. Mega Mart Warehouse had the exact part I needed for a fraction of the cost of ebay, amazon, and especially Viking parts. Was able to reassemble the convection unit, reinstall it, and have an oven that hasn't been that quiet or worked that well for years and it works perfectly. Part was delivered within a couple of days, packaged well, and was exactly what I needed. Will shop here in the future . . .
