Troubleshooting Chart
Symptom
Reset mechanism cuts
out repeatedly or circuit
breaker trips repeatedly

pressure when
compressors off and the
shut off valve is closed

out the unloader valve
Pressure switch does
not release air when
the unit shuts off
Excessive vibration
(Continued)
possible Cause(s)
1 . Lack of proper ventilation / room
temperature too high
2 . Too many devices on same circuit
3 . Restricted air intake
4 . Loose electrical connection
5 . Pressure switch shut-off pressure set
too high
6 . Malfunctioning check valve
7 . Defective unloader valve on
pressure switch
8 . Defective motor capacitor(s)
9 . Malfunctioning motor
1 . Air leaks (fittings, tubing on
compressor, or plumbing outside

3 . Clean or replace filter element
4 . Check all electrical connections .
5 . Replace pressure switch .
6 . Replace check valve .
Do not disassemble check
valve with air pressure in tank
7 . Replace unloader valve
8 .Replace capacitor(s)
9 . Replace motor .
1 . Check all connections with soap and water solution . Tighten; or
remove and apply sealant to threads, then reassemble .

Do not disassemble check
valve with air pressure in tank
3 . Replace tank . Never repair a damaged tank .
Replace the check valve if the unloader valve on the pressure switch
bleeds off constantly when unit shuts off .
Do not disassemble check
valve with air pressure in tank
Replace the unloader valve if it does not release the pressure for a
short period of time when the unit shuts off .
Do not disassemble check
valve with air pressure in tank
1 . Tighten fasteners .
2 . Replace with correct size .
