I dropped a plate on my Cooktop, it cracked the glass. I ordered the part from Appliance Part Pros, it took two days for the part to get to the house. I propped up the old Cooktop (did not completley remove it from the counter) and removed the 10 or so screws. Then pulled the old top out and put the new top on, replaced the screws and dropped the top back down. That was it, no issues the job took 30 min.
