What are these made of?? I have replaced the knobs 4 different times and they MELT when heat goes NEAR it.(My replacements ARE NOT chrome or stainless steel as stated by Jenn-Aire-part # 74009554) So I am hoping what you have is a better quality. Many Thanks
Answer Sandra, all the "proper" knobs for your cooktop are electro plated stainless steel, on a plastic based body(knob). They can become warped. discolored or "melt", when exposed to excessively high heat or excessive cook times. A couple of things to check, Are the gas flames from the burners the proper size and color(a blue flame with a distinct lighter blue color in the center), not a lot of yellow or white tips or streaks in the flame ? Are the bottom of the pans or pots 1 inch larger than the grate area ? ( oversized pots and pans can and will reflect the heat onto the cooktop surface and knobs. The part you referred to, is correct for your product74009554, and I believe you'll be more satisfied with the unit, if you review your owners manual, and replace the damaged burner knobs. Hope this was helpful, Thanks and Good Luck.
