PROBLEM POSSIBLE CAUSE POSSIBLE SOLUTION
Pressure drop in the tank Air leaks at the connections Let the compressor build up
pressure in the tank to
maximum pressure if possible.
Brush soapy water on the air
connections and look for air
bubbles. Tighten leaky
connections. If the problem
persists, contact your service
dealer
The unloader valve leaks when
the compressor is idle Unloader valve seal is
defective Let the air in the air tank flow
out until all the pressure is
released. Then remove the
unloader valve plug and clean
the valve seal. If necessary,
replace the seal and then
reinstall
The compressor stopped and
won’t restart The thermal protector turned
on because the motor is

rated or too long can cause
voltage drop and cause the
motor to overheat.
Allow the motor to cool down.
