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.

establish if that was the problem on
