Stephanie T Covington , KY February 04, 2017 My glass cooktop was scratched It was very easy to order the replacement glass from AppliancePartsPros.com and it arrived in two days. It took about 45 minutes to replace the glass. The old glass was 10+ years old so the new one looks fantastic and this fix was 1/3 of the cost of a new cooktop!
