Turn off the breaker. Open oven door. On the underside of the front panel, I removed 4 screws and trim panel. I also removed the 4 1/4" nuts. I pulled the front burner knobs off and removed those 4 screws. I also took out the 2 small screws on the underside of the front panel. Not all of these screws may have needed to come out.
The clock assembly board will then tilt forward. I used masking tape to hold it to free up both hands and took a photo of the connections, though I didn't need it. Three connections are swapped to the new board. The two plugs are easy.
The tricky thing is transferring the ribbon to its new connector. In computers, most ribbons stay with their connector, but not here. Pull up on the tabs on the old connector, pull out the ribbon itself, and place it in the new connector. There are slots on the ribbon which will catch on other tabs inside the new connector as you push the ribbon down.
Reassembly is the reverse. With cleaning, the job took about 20 minutes.
