Ordered the replacement part at AppliancePartsPros.com, which was easy to identify and order. Watched the generic installation video (and read the service manual) which was helpful, especially the warning about the short wires behind the oven wall. Sure enough, despite careful preparation and caution, one of the 4 wire connections immediately separated before I could wrap a twist-tie around it and disappeared behind the wall. Tried to fish it out without success, so pulled the built-in oven out of the cabinet. Aligned the replacement element up to install and it didn't fit! Called APP to report the problem, and APP planned to ship a new element. Then learned that moving the mounting bracket on the element that It relaxed somewhat and was able to install it. Called APP the next business day to cancel replacement shipment. Oven fixed!
