trips.
1. plug/receptacle is at fault or wired
incorrectly.
2. Motor connection wired incor rectly.
3. thermal overload relay has tripped.
4. Contactor not getting energized /has burnt
contacts.
5. power supply is at fault/switched o FF.
6. Motor on button or on/oFF switc h is at
fault.
7. Centrifugal switch is at fault.
8. Wiring is open/has high resistance.
9. Motor is at fault.
1. test for good contacts; correct the wiring.
2. Correct motor wiring connect ions.
3. turn cut-out dial to increase working amps and
push the reset pin. replace if tripped multiple
times (weak relay).
4. test for power on all legs and contac tor operation.
replace unit if faulty.
5. ensure hot lines have correct voltag e on all legs
and main power supply is switc hed on.
