Troubleshooting
Motor & Electrical
Symptom Possible Cause Possible Solution
Machine does not
start or a breaker
trips. 1. Plug/receptacle is at fault or wired incor-
rectly.
2. Start capacitor is at fault (single-phase).
3. Motor connection wired incorrectly.
4. Thermal overload relay has tripped.
5. Contactor not getting energized/has burnt
contacts.
6. Wall fuse/circuit breaker is blown/tripped.
7. Power supply is at fault/switched OFF.
8. Motor ON button or ON/OFF switch is at
fault.
9. Centrifugal Switch is at fault (single-phase).
10. Wiring is open/has high resistance.
11. Motor is at fault.
12. Start delay module is at fault.
1. Test for good contacts; correct the wiring.
2. Test/replace if faulty.
3. Correct motor wiring connections.
4. Unplug machine, open magnetic switch cover, turn
amperage dial on Thermal Protection Circuit Breaker
to a higher amperage setting.
5. Test for power on all legs and contactor operation.
Replace unit if faulty.
6. Ensure correct size for machine load (refer to Page
12); replace weak breaker.
7. Ensure hot lines have correct voltage on all legs and
main power supply is switched ON.
8. Replace faulty ON button or ON/OFF switch.
9. Adjust/replace the centrifugal switch if available.
10. Check for broken wires or disconnected/corroded
connections, and repair/replace as necessary.
11. Test/repair/replace.
12. Adjust to correct delay; replace module.
Machine stalls or is
underpowered. 1. Applying too much pressure to workpiece.
2. Run capacitor is at fault (single-phase).
3. Belt(s) slipping.
4. Motor connection is wired incorrectly.
5. Plug/receptacle is at fault.
6. Motor bearings are at fault.
7. Motor has overheated.
8. Contactor not getting energized or has poor
contacts.
9. Motor is at fault.
10. Centrifugal switch is at fault (single-phase).
11. Start delay module at fault (3-phase only).
1. Use sharp blade, and reduce the feed rate.
2. Test/repair/replace.
3. Replace bad belt(s) as a matched set, align pulleys,
and re-tension.
4. Correct motor wiring connections.
5. Test for good contacts; correct the wiring.
6. Test by rotating shaft; rotational grinding/loose shaft
requires bearing replacement.
7. Clean off motor, let cool, and reduce workload.
8. Test for power on all legs and contactor operation.
Replace if faulty.
9. Test/repair/replace.
10. Adjust/replace centrifugal switch if available.
11. Adjust to correct delay; replace module.
