Trouble
Machine will not
start/restart or
repeatedly trips
circuit breaker or
blows fuses.
(cont.)
Probable Cause
Motor starter failure.
Motor failure.
Miswiring of the unit.
On/off switch failure.
Remedy
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.
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.
Check to confirm all electrical
connections are correct and properly
tight. Make any needed corrections.
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.
