Symptom Possible Cause Correction *
Machine will not
start/restart or
repeatedly trips circuit
breaker or blows
fuses.
(cont.)
Motor starter failure.
Examine motor starter for burned or
failed components. If damage is found,
replace motor starter. If motor starter
looks okay but is still suspect, you have
two options: have a qualified electrician
test the motor starter for function, or
purchase a new starter and establish if
that was the problem on changeout.
If you have access to a voltmeter, you
can separate a starter failure from a
motor failure by first, verifying incoming
voltage at 230+/-10% and second,
checking the voltage between starter
and motor at 230+/-10%.
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.
Motor failure.
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 qualified electric
motor repair shop and have it tested.
Miswiring of the unit.
Check to confirm all electrical
connections are correct and properly
tight. Make any needed corrections.
On/off switch failure.
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.
* WARNING: Some corrections may require a qualified electrician.
