Hi there. Nate with AP Appliance here. I see that this post is a couple years old, so I don't know if you ended up figuring it out, but in case it will help someone else who sees this post, I'll share some disassembly instructions. On the top, at the back of the range, sits your cast iron oven vent cover. Lift it off and set it aside. You'll see 3 screws under it. Remove them. Now remove your gas burner grates/rings. They should just lift off. Underneath, next to your orifices, you'll see screws. 2 for the small burners, 3 for the large one, and 4 for your middle oval burner. Remove them. You can now grasp the cooktop from the back and lift up. Once you lift it up, you can slide it back slightly, releasing the tabs at the front of the cooktop from their grooves, and it will come off. Now, take all of your knobs off of your front control. Behind them are screws. 4 screws behind each knob. 2 of those screws hold the chrome/plastic bezels on the panel, the other 2 hold the panel on the range. (The panel removal screws have small circular alignment pins next to, or above them.) Remove those screws. Now, with some effort, and some slight lifting, the panel will pop free. You can now unplug the wires from the circuit board and remove the panel. To remove the control board from the panel, you'll need to unplug the ribbon connector of the touch screen from the circuit board. To do this, there's a long, thin piece of plastic (almost an inch long) on the board where the ribbon plugs into that must be rotated upward toward the ribbon to release the ribbon. Lastly, there are 2 screws holding the board down, one on each end. Remove those. You can now lift the board out. To install the new board, follow these instructions in reverse.
