Product review (1 stars): Safety Hazard!!
These knobs should not be sold on Amazon.  First you can tell these are cheap parts with the printed on numbers and "heat" direction arrows that are fading.  Then the plastic is very cheap (they will melt), and I felt unsafe putting these on an oven when kids will be around it.  Do not buy from this seller. I called Frigidaire and they provided me assistance with getting approved and tested parts.
