Replaced main glass cooking surface on cooktop

First, shut of the breaker to the cooktop.

Then removed two screws to release brackets holding cooktop down. Then lifted the cooktop out of the recess in the counter top and removed the screws around the outside of the glass top. Removed the old, cracked top, by unplugging from the motherboard.

Turned the new cooktop upside down on table and placed weather stripping around the entire underside outside edge (to keep spills from going under the cooktop and cushion the cooktop from the counter top.

Then plugged the new cooktop into the motherboard, replaced screws around outside edge, lowered the cooktop into the recess in the counter, and reinserted the two screws into the hold-down brackets.

Turned the breaker back on.
