Our cooktop is about 9 years old. Great appliance, but poor engineering/design choice to have aluminum knobs with plastic knob shafts, that almost every time the burner gets turned on, the plastic shaft gets stressed and they crack, rendering them useless over time. I replaced all five (5), for about $80 delivered, since I got tired of repairing them. I did see a very helpful post from a guy in Arizona (thanks if you're reading this) whose daughter glued the shafts inside and out, and then wrapped them in wire. I did the same thing with my spares (I have about 7 now, after replacing one or two over the years), as I took the metal sleeve out of the middle, glued them inside and out, and used small plastic wire ties to close them up tight, then putting the metal insert back inside. After the glue dried, I snipped off the end of the wire tie. It worked great! Thanks, Tom D., from outside Boston, MA.
