Replacement of glass top

Check your warranty in the back of your use and care book. If the unit was manufactured prior to 1/1/06 it may have a five year part (not labor) warranty as long as you did not physically abuse it. The glass top comes as an assembled top (glass, the black seal, and the metal frame holding it)
Disconnect power. remove screws under the front edge of cook top. lift cook top and remove crossbars holding burners up against glass top. Unhook cook top / frame assemble. Install new top in reverse order.

I cracked my stove top where can i order it and install it

Just a note when you're doing this... when you open up the top, put a towel across each side so that when you drop a clip, it doesn't go down the side between the oven and the outside wall. If it does, hope that it goes all the way to the bottom where you can get at it by removing the bottom drawer. If you put the towel all the way across the oven box before you start taking things apart, you also won't have to worry about where little tiny screws go when you drop them... and, you will drop them! ;-)

Also, the old tops had a reinforcement bar that the ground was attached to. The new ones don't. There's a tiny hole on the flange of one of the right hand burner holes... that's where the ground is supposed to go on the new top. You WILL need a smaller self tapping screw than the original one.

And, forget having a helper... get something to prop the lid open with that won't fall if you raise the lid a little while you're working on it. Helper will just get in the way and can't hold it still enough while you''re trying to man handle those tiny little clips and screws that hold the burners in place.
