SECTION 7: SERVICE
Troubleshooting
Motor & Electrical
Symptom
Possible Cause
Possible Solution
Machine does
not start, or
power supply
breaker
immediately
trips after
startup.
1. Tank already pressurized.
2. Internal overload tripped.
3. Incorrect power supply voltage or circuit size.
4. Pressure switch cut-in/cut-out settings have
been adjusted incorrectly.
5. Power supply circuit breaker tripped or fuse
blown.
6. Tripped thermal overload in motor,
compressor is exceeding its duty cycle.
7. Wiring broken, disconnected, or corroded.
8. Check valve components are dirty/damaged.
9. Pressure switch at fault.
10. Internal overload at fault.
11. Motor or motor bearings at fault.
1. Motor will not start if tank is fully pressurized.
2. Disconnect machine from power, allow pump to cool,
then resume operations.
3. Ensure correct power supply and circuit size
(
Page 11).
4. Adjust settings (
Page 30). Do not exceed cut-in/cut-
out pressures listed on data sheet (
Page 6) or inside
pressure switch.
5. Ensure circuit is free of shorts. Reset circuit breaker or
replace fuse.
6. Reduce load on compressor and allow longer cool
down periods.
7. Fix broken wires or disconnected/corroded
connections.
8. Clean/replace check valve components (
Page 29).
9. Turn compressor
OFF, disconnect from power, and
empty tank. DO NOT USE until switch is replaced.
10. Replace pump.
11. Replace motor.
Machine
stalls or is
underpowered.
1. Air filter(s) dirty/clogged.
2. Pump/motor have restricted airflow.
3. Pressure switch cut-in/cut-out settings have
been adjusted incorrectly.
4. Motor overheated, tripping internal overload;
compressor is exceeding its duty cycle.
5. Run capacitor at fault.
6. Extension cord too long.
7. Check valve components are dirty/damaged.
8. Motor or motor bearings at fault.
9. Worn valves or rings/compressor pump at
fault.
1. Replace air filter(s) (
Page 23).
2. Clean cylinder fins, motor fan, and vent area.
3. Adjust settings (
Page 30). Do not exceed cut-in/cut-
out pressures listed on data sheet (
Page 6) or inside
pressure switch.
4. Reduce load on compressor and allow longer cool
down periods. Clean motor, let cool, and reduce
workload. Reset breaker.
5. Test/repair/replace.
6. Move machine closer to power supply; use shorter
extension cord.
7. Clean/replace check valve components (
Page 29).
8. Replace motor.
9. Rebuild/replace.
