0. Disconnected the dryer power supply
1. Removed the control panel (3 screws, star bit)
2. Detached the electric power supply cords from the timer assembly (took a bit of easing back and forth - do not pull by the electric cords, pull the socket itself)
3. Timer assembly eased off subsequently (held in place by three unscrewed receptacles)
4. Installed the new timer assembly, plugged back the supply cords, and installed the new timer knob, skirt and chrome cap.
They don't build Maytag equipment as they used to. We bought a fridge, washer and dryer 6 years ago - all three of them have had component, part stress and/or electronic sensor failures :-(
