TROUBLESHOOTING
WARNING - Make sure you completely understand all of the safety warnings and operation of each
system control component before attempting any maintenance or repair. Always drain the tank pressure
completely, make sure the power cord is unplugged, and unit has time to cool before performing any
maintenance or service operations.
PROBLEM
CAUSE SOLUTION
Motor makes no noise when
power is applied
Tank pressure is full Drain below 95 PSI to restart
Automatic overload has stopped
compressor due to overheating
Unplug, drain tank pressure and
allow to cool before restarting.
Evaluate power supply and
extension cord used
Motor hums but does not
start/run Motor windings are fried
Take in for service. Evaluate
power supply and duty cycle
Capacitor has failed Replace and retest
Motor runs but pump will not
reach top pressure setting of 125
PSI
Excessive external leaks at tank
drain, regulator, hoses, etc. Use soap/water solution to
identify and correct leaks
Broken valve, blown gasket or
other internal issue Inspect valve plates or take in for
service
Unit does not maintain tank
pressure after stopping at 125 PSI
and leaks continuously from
solenoid
Disc and spring inside check valve
are not sealing
Drain tank pressure completely.
Unthread check valve inspection
cap and clean debris from disc
Unit runs great for close to an
hour before suddenly stopping
Excessive external leaks on unit or
air hose/fittings Use soap/water solution to
identify and correct leaks
Unit is undersized or is being
worked above 70% duty cycle Use larger air compressor for this
application
Pump builds tank pressure above
125 PSI, causing safety valve to
blow/pop off
Pressure switch contacts are
stuck together
Unplug, inspect contacts and
replace pressure switch if
necessary
Pressure switch port is plugged
with ice or debris
Bring inside to unthaw drain water
from tank and restart or take in
for service
Compressor is louder than normal
and slow to build pressure Broken valve, bearing failure or
debris inside pump Inspect valve plates and piston
tops or take in for service
