TROUBLESHOOTING
Visit a Princess Auto Ltd. location for a solution if the device does not function
properly or parts are missing. If unable to do so, have a qualified technician
service the device.
Problem(s)
Possible Cause(s)
Suggested Solution(s)
Motor will not
start.
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.
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.
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.
