John D Salinas , CA June 24, 2017 Appliance: Model WHIRLPOOL COOKTOP BLACK PART #: AP4358970 (W101 Cooktop had shattered likely from excessive heat Ordered the part and installed myself. Received payout from home warranty of $750 since they could not source the part quickly. I decided to order the part online through appliancepartspro since they were the best price. Repair was very straightforward and easy. 10 screws around the cooktop for easy removal, longest part was vacuuming out the old glass. The cooktop set into place and really did not need any sealer since it was heavy enough to sit back in place without moving. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
