SYMPTOM POSSIBLE CAUSE
POSSIBLE SOLUTION
on
Machine does not
start or a breaker
trips immediately
after startup.
1. Switch disabling key removed.

size.
3. Power supply circuit breaker tripped or
fuse blown.
4. Wiring open/has high resistance.
5. Start capacitor at fault.
6. ON/OFF switch at fault.
7. Motor at fault.
1. Install switch disabling key.
2. Ensure correct power supply voltage and circuit
size.
3. Ensure circuit is sized correctly and free of shorts.
Reset circuit breaker or replace fuse.
