The timer is located behind the cycle control knob and contains the programs or function sequences for all the major wash cycles. The program is contained inside the timer in a plastic drum with raised ridges on it (see Wash Cycle Control section of Proper Operation). Banks of switches are mounted on the drum. The end of the middle blade of the switch is resting on a plastic cam follower which rides on the drum ridges. The drum is turned by the little synchronous motor mounted on the timer. This motor and its gear train rarely fail. As the drum turns, the switches open and close to stop and start the agitate, drain, spin and fill functions. The switch contacts can fail when they become burned and pitted with use. They can also weld together and account for some awfully long agitate cycles.
The timer controls the sequence of all major functions. Timer problems are usually consistant across all major cycles such as normal, permanent press, or prewash. A major function such as agitate or spin will be messed up on all cycles. You may not be able to get the machine to do anything if the push-off/pull-on switch has failed. If the timer shaft has separated from the plastic wheel at the end, you will not be able to select a cycle or turn the machine on or off. Excessive force when pulling the control knob out or pushing it in can cause this separation. This white plastic wheel is visible from the backside of the timer.
