Gene - The model number is the same as the one above, i.e., KECD865HBL3
. It's the black model.
Two issues: The first is that the "On" light doesn't go off. The burner is not on. The burner that is involved is the dual-coil burner. This seems to be the same issue as was originally mentioned in this thread.
The 2nd issue is that the burners seem to swap between very high heat and off no matter what setting you put them on. Even at the lowest setting, they seem to fluctuate between "hi" and "off". I don't know if replacing the switches would elimiate this, or if it's some sort of a burner issue. The cooktop was in our home when we bought it (3 years ago), but it was installed in September 2001.
