I turned off the main breaker to the oven to disconnect power. I removed 4 screws that held the built in unit in place. Then pulled the oven out and removed 2 screws on either side of the old control panel. Then pulled the Control Panel off and laid it face down. I removed 4 screws and the 2 ribbons that connect the Control Panel to the PC Control Board. Then just reversed that process to connect the new Control Panel. I had to adjust the Control Panel in and out a couple times to get it flush with the oven unit. Turned the power back on and it worked fine.
