John H Columbia , MO December 21, 2020 Appliance: Model JENNAIR Glass cooktop ap6016989 My wife left the burner on and accidentally put an old Tupperware lid on the burner and didn't turn the burner off. We were eating in the living room and all of a sudden heard a loud crack from the kitchen. The glass was cracked and part of it melted. The Jenn Air is 14 years old so we looked at the prices of the new downdraft stove oven combinations. $3-4 thousand dollars so I looked on the internet and found your company. Gave the customer service rep the numbers and they gave me the price. She recommended the glass cleaner which I bought. I suggest you also recommend a screw kit for the burners underneath the glass. Some were stripped when I reinstalled and had to substitute. Do-It-Yourself Rating: Repair Time Estimate: 2+ hours
