It was a simple process to enter the model number of our glass cook top stove; learn the part number required and order. It arrived in 2-days -- least expensive shipping method.
The cooktop was removed with a Phillips-head screwdriver by 4 small sheet metal screws on the right and left side of the oven.
The oven's power to the cooktop was easily disconnected via two "clips" and one ground.
Would have cost way more with an appliance repair shop and it's an easy do-it-yourself repair.
