6. Start capacitor is at fault.
7. Motor is at fault.
1. test for good contact or correct the wiring.
2. Correct motor wiring connections (
page 51).
3. ensure hot lines have correct voltage on all legs and
main power supply is switched on.
4. replace faulty on/oFF switch.
5. Check for broken wires or corroded/disconnected
connections, and repair/replace as necessary.
