How to replace a range glass cooktop
The ceramic glass main top on a range provides a flat, smooth cooking surface; radiant elements attached under the main top provide heat. If the glass cracks or is otherwise damaged, stop using the cooktop elements until you can replace the glass top with a manufacturer-approved range part, following the steps in this DIY repair guide and video. Otherwise, the heat of cooking could expand the crack, and the glass could shatter.
This repair procedure is for installing the stove top replacement glass on Kenmore 790-series and Frigidaire free-standing ranges. You also can use the same basic stovetop replacement glass top installation process on many Whirlpool, KitchenAid, Maytag, Amana, GE, LG and Samsung ranges.

Turn off power to the range
Unplug the range or shut off the circuit breaker for the range.Tip: Shutting off the circuit breakers for the range works best for this repair because you don’t have to pull the range out of the cabinet. If you pull out the range to unplug it, use cardboard under the range to protect the floor from scratches.
Open the cooktop
Open the oven door completely and remove the screws from the bottom front lip of the glass cooktop frame.
Carefully pull the cooktop assembly slightly forward to release the front lip of the glass cooktop frame from the front cabinet support bracket. Raise the front of the cooktop slightly to release the frame sides from the front support bracket then pull the cooktop forward to release the hinge tabs from the slots in the backguard.
Lift the front edge of the glass cooktop and prop it open.
Place the prop at the front of the range under the center of the cooktop’s front lip where it's steady, so the cooktop won't fall. Avoid damaging the oven cavity insulation when propping open the glass cooktop.
