Troubleshooting
Problem Possible Causes Likely Solutions
Compressor does
not start or restart
1� Tank(s) already pressurized�
2� Power cord not plugged in properly�
3� Incorrect power supply�
4� No power at outlet�
5� Thermal overload switch tripped�
6� Building power supply circuit tripped or
blown fuse�
7� Cord wire size is too small or cord is
too long to properly power compressor�
8� Compressor needs service�
1� Check pressure gauges� If pressurized, no
problem� Compressor will start when needed�
2� Check that cord is plugged in securely�
3� Check that circuit matches compressor requirements�
4� Reset circuit breaker, or have outlet
serviced by a qualified technician�
5� Turn off Compressor and wait for it to cool down�
Press reset button� Resume operation�
6� Reset circuit or replace fuse� Check for low voltage
conditions� It may be necessary to disconnect
other electrical appliances from the circuit or
move the compressor to its own circuit�
7� Use larger diameter or shorter extension cord or
eliminate extension cord� See Recommended Wire
Gauge for Extension Cords in Safety section�
8� Have unit inspected by a qualified technician�
Compressor builds
pressure too slowly
1� Incorrect power supply�
2� Working environment too cold�
3� Safety valve leaking�
4� Loose fittings�
1� Check that circuit matches compressor requirements�
2� Move compressor to a warmer location�
3� Listen for air leaking from valve�
If leaking, replace with identical valve with same rating�
DO NOT SEAL OR TAMPER WITH SAFETY VALVE.
4� Reduce air pressure, then check all fittings with
a soap solution for air leaks and tighten as needed�
Do not overtighten�
Compressor not
building enough
air pressure
1� Air filters need cleaning/replacing�
2� Check Valve needs service�
3� Compressor not large enough for job�
4� Loose fittings�
5� Hose or hose connections too narrow�
6� High altitude reducing air output�
1� Check inlet and outlet filters�
Clean and/or replace as needed�
2� Have technician clean or replace, as needed�
3� Check if accessory CFM is met by Compressor�
If Compressor cannot supply enough air flow (CFM),
you need a larger Compressor�
4� Reduce air pressure, then check all fittings with
a soap solution for air leaks and tighten as needed�
Do not overtighten�
5� Replace with wider hose and/or hose connections�
6� Higher altitudes require compressors with greater output�
Fuses blow/
circuit breaker
trips repeatedly
1� Incorrect size fuse, circuit overload�
2� Wrong gauge wire or length
of extension cord�
3� Defective check valve or under loader�
1� Check for proper fuse, use time-delay fuse,
disconnect other electrical appliances from circuit
or operate compressor on its own branch circuit�
2� Check for proper gauge wire and cord length�
3� Take compressor to service center�
Follow all safety precautions whenever diagnosing or servicing the compressor.
Disconnect power supply before service.
