REMEDIES
Verify the fuses are not
blown, a circuit breaker has
not tripped (also check the
breaker for controls), and the
heaters are not overloaded.
The wiring, heater switches
and starter must be inspected
for possible damage prior to
starting.
Make sure the motor is wired
across the proper voltage.
The required voltage is indi-
cated on the motor label.
With the circuit de-energized,
check for continuity using an
ohmmeter.
Confirm the circuit is wired for
single-phase or three-phase
and the motor is grounded.
Check safety shut-off circuitry
to make sure the necessary
circuit by-passes are in place
to start the motor.
Check single-phase motor
controller and verify that it is
in working order. See detailed
label inside controller box.
Check the amp draw through
each leg leading to the motor
using an ammeter. The read-
ings should not exceed the
maximum amps (S.F.A.) indi-
cated on the motor label.
POSSIBLE CAUSES
Blown fuse, tripped circuit
breaker or overloaded
Line voltage connection dif-
ferent from motor voltage
Bad connection
Motor wired improperly
Shut-off controls disabling
circuit.
Single-phase motor controller
not operational
Motor exceeding rated amp
draw
PROBLEM
Motor does not run
Motor runs, then stops
