This owner’s manual (Use and Care Guide) for my range says it’s for models: KGRT607 KGST307 KGRT600 KGST300 YKGRT607 YKGST307.
The instructions to remove and replace the door are in the owner’s manual near the front in the Features section. But here’s and even easier way to remove the door.
Open the door to the broil stop position (open about 4”). Grasp the sides of the door down near the hinges. Raise up on the door and then pull it away from the range. It comes right off.
To clarify reinstalling the door --
Place the top of the door under the cooktop overhang. Line up the hinge plates with the slots. Apply pressure to the bottom of the door with the side of your leg so approximately the first 2 inches of the plates go into the cabinet. The plates will only go part way into the cabinet at this stage, you will still have 2-3 inches of the hinge plate showing. Now, tip the top of the door away from the cabinet to about the same angle as the 4” open broil position. Push on the bottom of the door to slide the hinge plates into the cabinet slots until they seat.
How to replace the glass --
The main hint is that the disassembly is done from the front, once you remove the front glass from the door you can continue with the disassembly and work your way down to the broken glass.
I recommend taking photos of the door as you proceed with disassembly. Mark some of the parts with a Sharpie pen (Left or Right, etc) as a reminder about how to reassemble.
Lay the door on padded surface with exterior glass face up. Let hinges hang off the table.
Remove the bottom trim that holds the exterior glass.
Slide the glass down to release it from the tabs on the top edge, remove the glass.
Remove remaining screws from the bottom of the door.
Remove the side trim pieces.
Remove two screws that hold the top of the door and the handle to the frame, remove that assembly.
At the top of each hinge there’s a tab that fits in a slot in the frame. To keep the tab from
coming out of the slot there’s a metal retainer and a clip screwed to the top of the hinge. Remove the screw and the retainer.
Remove both hinges.
Lift off the frame that covers the two sheets of interior glass.
Between the middle layer glass and the layer closest to the oven there is another frame held by nine (?) screws and clips. As others have mentioned, these screws are difficult to loosen. I used an impact driver to remove these screws. When I reassembled the door I only tightened these screws to a normal firm tightness with a screwdriver.
Replace the broken glass and reassemble the door by reversing steps.
