The washer would not spin during it's cycle.

I realized the switch was bad when I found that I could put a screwdriver through the hole and press the switch and the spin would continue. To replace, I removed the screws from the back of the control unit. I disconnected the plastic switch connection and lay the entire outer shell of the washer down on the ground. At this point you can see the old switch. Remove the screws holding the old switch in place. Take it out and replace it with the new switch. Put the shell back in place, connect the plastic switch connector, screw on the control unit and your done. I don't know anything about washers so I was pleasantly surprised that this went so smoothly.
