Bought replacement element. Unplugged range. Removed 2 screws under range top and glass hinged up. Propped with 2x4. Noticed one of the spade connectors for the inner section of element was broken. Removed all connectors and used screwdriver to pry up the 2 clamps holding the element in place. Installed new element, making sure to line up small spikes on clamp connectors with holes in element (digs into ceramic material). Reconnected spade connectors after removing deteriorated heat shrink. Not sure what temp. heat shrink for those connectors should be rated up to, but whatever was there didn't cut it. Plugged back in and tested. Working fine now.
