Small Element on cook top fails to function

Turned of the electric at the circuit breaker. Removed the cable clamps for the electric feed cable to enable free movement of cooktop. Lifted cooktop from the counter and propped up on counter ledge. Removed control knobs. Removed perimeter screws, 8 phillips, from around the edge of the cook top surface where it attaches to the sheet metal housing and lifted glass top off. Removed the failed burner and disconnected the four electrical leads. Removed the mounting tabs from the old burner and installed them on the new burner. Attached the electrical leads to the new burner and tightened with pliers. Reattached glass top and knobs, reinstalled in counter, clamped the electrical cable, flipped the breaker and tested. All good.
