automatic operations or performs a specific part of the cycle continuously, but works okay on manual. Remember, the
timer motor is controlled by the start switch and the hold micro switch, check this complete circuit before changing
motor. The motor is replaced by:
1. Remove motor leads from connection points.

3. Replace with new motor.
4. Re-connect motor leads to proper points.
