This is a fairly new cook top (under 1 year) and one of the knob is completely stuck (it feels stuck to a point I cant rotate the burner knob at all). I pull off the knob, there is nothing that is visually different compared to others. I also notice most of the knob's show cracking (though they rotate).
Is this is a known issue? The fact that the knobs show cracking on a new range is a bit scary.
Thanks in advance
