Remove control knob
The black arrow points to the control knob. Push it inward as you would to turn the machine “off.” You can turn the push/pull knob counter-clockwise and it will unscrew from the timer shaft (red arrow). Pull the round indicator plate behind it off, too.
Access the timer The timer is behind the control panel. Our machine is a Sears Kenmore. Grasp the plastic end caps at the top and pull forward.
Remove screws Two screws, one on each side of the control panel, must be removed. The one on the right side of the machine is shown here. Lift and pull the control panel forward from the rest of the washing machine. Two screws hold the timer against the front of the control panel. They were visible after removing the control knob and indicator in the last step. Remove these screws, too. Disconnect the wiring harness from the timer and remove the timer.
Reassembly Two paws need to be held back so the white plastic wheel with the cams and teeth on it can be fully inserted into the timer frame. The file on my PST Leatherman tool is pointing at the paws. I used it to hold the paws back.
