Matthew S Herndon , VA July 13, 2014 Appliance: Kenmore Gas Range 79036679400 Kenmore Range 79036679400: Broken clock/timer control board for oven. How to replace Clock Timer. It was easy to replace the old clock/timer control board with the new one. I followed these steps: 1. Remove the four control knobs. 2. Remove the four large plastic nuts under the control knobs. This holds down the entire faceplate. 3. Remove the four screws which secure the clock/timer control board and display. 4. Lift up the control board, and remove the multi-pin connector (needed to use a flathead screwdriver to pry open connector tabs). 5. Replace old control board with new control board. 6. Replace the cover plate. 7. Insert the four screws from step 3. 8. Insert the four nuts in step 2. 9. Replace knobs. Done!
