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. Incorrect power supply voltage or circuit size.

3. Plug at fault/wired incorrectly.
4. Pressure switch cut-in/cut-out settings have

been adjusted incorrectly.

5. Power supply circuit breaker tripped or fuse

blown.

6.  Motor wires connected incorrectly.
7.  Start capacitor at fault.
8.  Centrifugal switch adjustment/contact points

at fault.

9. Wiring broken, disconnected, or corroded.

10. Tripped motor thermal overload; compressor

is exceeding its duty cycle.

11. Check valve components are dirty/damaged.
12. Pressure switch at fault.

13. Motor or motor bearings at fault.

1. Motor will not start if tank is fully pressurized.
2. Ensure correct power supply voltage and circuit size

(

Page 11).

3. Test for good contacts/correct wiring (

Page 39).

4. Adjust settings (

Page 35). 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. Correct motor wiring connections (

Page 39).

7. Test/replace if at fault.
8. Adjust centrifugal switch/clean contact points. Replace

either if at fault.

9. Fix broken wires or disconnected/corroded

connections (

Page 39).

10. Reduce load on compressor and allow longer cool

down periods.

11. Clean/replace check valve components (

Page 33).

12. Turn compressor

OFF, disconnect from power, and

empty tank. DO NOT USE until switch is replaced.

13. Replace motor.

Machine
stalls or is
underpowered.

1.  Air filter(s) dirty/clogged.
2.  Pump/motor have restricted airflow.
3.  Belt slipping/pulleys misaligned.

4. Motor wires connected incorrectly.
5. Pressure switch cut-in/cut-out settings have

been adjusted incorrectly.

6.  Plug at fault/wired incorrectly.
7.  Pulley slipping on shaft.
8.  Tripped motor thermal overload; compressor

is exceeding its duty cycle.

9. Crankcase oil is not correct type.
10. Run capacitor at fault.
11. Extension cord too long.

12. Check valve components are dirty/damaged.

1. Replace air filter(s) (

Page 26).

2. Clean cylinder fins, motor fan, and vent area.
3. Clean/tension/replace belt (

Page 27); ensure pulleys

are aligned (

Page 36).

4. Correct motor wiring connections (

Page 39).

5. Adjust settings (

Page 35). Do not exceed cut-in/cut-

out pressures listed on data sheet (

Page 6) or inside

pressure switch.

6. Test for good contacts/correct wiring (

Page 39).

7. Tighten/replace loose pulley/shaft.
8. Reduce load on compressor and allow longer cool

down periods.

9. Drain and replace with correct oil (

Page 25).

10. Test/repair/replace.
11. Move machine closer to power supply; use shorter

extension cord.

12. Clean/replace check valve components (

Page 33).
