6. Motor starter failure.
7. Motor failure.
8. Miswiring of the unit.
9. On/off switch failure.
6. (continued)
If you have access to a voltmeter, you
can separate a starter failure from a
motor failure by first, verifying incoming
voltage at 220+/-20 and second,
checking the voltage between starter and
motor at 220+/-20. If incoming voltage is
incorrect, you have a power supply
problem.
If voltage between starter and motor is
incorrect, you have a starter problem.
If voltage between starter and motor is
correct, you have a motor problem.
7. If electric motor is suspect, you have two
options: Have a qualified electrician test
the motor for function or remove the
motor and take it to a quality electric
motor repair shop and have it tested.
8. Double check to confirm all electrical
connections are correct and properly
tight. The electrical connections other
than the motor are pre-assembled and
tested at the factory. Therefore, the
motor connections should be double
checked as the highest probability for
error. If problems persist, double check
the factory wiring.
9. If the on/off switch is suspect, you have
two options: Have a qualified electrician
test the switch for function, or purchase a
new on/off switch and establish if that
was the problem on changeout.
