Trouble shooting electrical, expected a bad motor. Motor was good, Shorted pins, at timer, that runs motor and motor ran. Timer was not closing contacts to run motor. Ordered and replaced timer. All works fine now. I had a different wiring issue that agent helped me to correct on safety contacts. Wiring diagram only showed going to that switch with 4 wires, not where those wires connect to which contacts ( they are not numbered on the switch ). Her effort and patience were greatly appreciated. Trouble shooting took longer, but installing the timer took less than 15 minutes since the back was already off.
