Mike H Springfield , MO February 03, 2020 Appliance: Model GE J BS27G S1AD Clock/timer gone This was pretty simple as all I needed to do was to remove the old clock/timer and replace it. I took the back panel off the oven and the clock/timer had two wires with "spade" connections. I pulled them off and re-attached them to the new. There were 4 small screws to re-attach the unit to the stove and that was it. Put the back panel on and program the clock. Done! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
