Problem(s)
Possible Cause(s) Suggested Solution(s)
Motor is
overheating.
Broken or
disconnected
ground.
Reconnect or replace the ground wire and test for
proper ground.
Hot power lead is
connecting to the
motor frame.
Have a qualified technician inspect the motor and
repair/replace the defective wiring.
Motor overloads
during operation.
1.
A moving part of the motor may be binding.
Inspect the motor to see if any parts are
touching. Check to see the motor’s shaft is
straight.
2.
Run the motor under normal load and check
the amount of current it is drawing.
3.
Disconnect the motor from its load and
check the current drawn while running under
no-load.
4.
If the current draw is excessive under load,
but normal when there is no-load, Inspect
the load to determine the problem.
5.
If the no-load current is above the listed
rating, have the motor serviced or replaced
by a qualified technician.
Starting windings
remain active in
circuit as motor
accelerates.
Switch motor off to listen for a click. This is the
centrifugal switch closing as the motor slows.
Worn or poorly
lubricated
bearings.
Damaged or poorly lubricated bearing can be
heard. This may be a result of wear, inadequate oil
reaching the bearings or the motor overheating.
Contact Princess Auto Ltd. for a solution.
Inadequate
ventilation reaching
the motor.
Clean/clear all ventilation openings. Use dry
compressed air if blowing debris out of the
ventilation openings.
