start.
10
1-1/2 HP Totally Enclosed Air Over Electric Motor
Possible Cause(s)
1. There is a blown fuse
or open circuit
breaker.
2. Motor starter
overload activated.
3. The thermal switch is
open.
4. Low or no voltage
reaching motor.
5. Power enters control
circuit but does not
reach the motor.
Suggested Solution(s)
1. Test for voltage at the fuse or circuit
breaker. Also see if the voltage/amp
rating of the fuse or circuit breaker is
correct for the motor. It should
exceed the Motor's FLC by 25
percent.
2. Let cool and then reset overloads.
Test the starter before starting motor
again.
3. Reset the thermal switch, but beware
as the motor may automatically start
when reset. Press the push button
firmly until a snap is heard.
4. Check each motor terminal's voltage.
The voltage should be within 10% of
the voltage on the motor's nameplate.
Disconnect the load and apply power
to the motor. If the motor operates
normally, then the issue is with the
load attached to the motor. Should
the motor still not work, have it
serviced or replaced by a qualified
technician.
5. Begin by confirming all contacts are
clean and tight. Examine for obvious
damage.
a. Test each part of the circuit for
power until the problem area is
discovered.
b. Have a qualified service technician
repair or replace the circuit.
