I’ve had my GE Cafe 36 inch range for about 9 months now. So far I’ve had a few grates and a grate rack crack. It was repaired under warranty but now I’m worried about long term with the remaining grates and warranty coming to an end. Anyone else having this issue? In talking to a rep, it sounds like prolonged heat is known to cause this (both cases I was making to stir sauce). Thanks!
