Is anyone else having problems with small cracks on the floor of their oven? My range isn't even 2 years old and when I wipe the bottom there are sharp little bits of the finish on the rag. I have been afraid to use the self clean cycle (which is a feature I specifically shopped for). Can this be repaired somehow? Seems like the finish is defective and it is going to be harder and harder to clean as more of the finish chips off.
