Problem
Possible Cause
Solution
The compressor does
not run.
Loss of power or overheating.
There is no electrical power being
supplied to compressor or the power
switch is in the OFF position.
A fuse has blown at the power supply.
A breaker has tripped at the power supply.
Thermal overload open.
The pressure switch is bad.
Tank is full of air.
Check for proper use of extension cord.
Check to be sure the compressor is plugged
in and the power switch is in the ON position.
Replace the fuse at the power supply.
Reset the breaker at the power supply and
determine why the problem happened.
First unplug the compressor and wait until it
becomes cool. Motor will restart when cool.
Replace the pressure switch.
Compressor will turn on when tank pressure
drops to cut-in pressure.
The motor hums, but
does not run or runs
slowly.
The voltage from the power supply is low.
The gauge wire or the length of extension
cord is wrong.
The motor winding is shorted or broken.
The unloader or check valve is defective.
Check the voltage with a voltmeter.
Use the correct wire gauge and length
extension cord.
Take the compressor to a service center.
Take the compressor to a service center.
The fuses blow or the
circuit breaker trips
repeatedly.
The fuse size is incorrect or the circuit is
overloaded.
The gauge wire or the length of extension
cord is wrong.
The unloader or check valve is defective.
Check the fuse or breaker at the power supply
is the correct size and type. Be sure to use
only time-delay fuses to avoid overloading a
curcuit, disconnect other electrical appliances
from circuit or operate compressor on its own
branch circuit.
Use the correct wire gauge and length
extension cord.
Take the compressor to a service center.
The thermal overload
protector cuts out
repeatedly.
The voltage from the power supply is low.
A poorly ventilated room is causing the
motor to overheat.
The gauge wire or the length of extension
cord is wrong.
Check the voltage with a voltmeter.
Move the compressor to well-ventilated area.
Check for proper gauge wire and cord length.
The air receiver
pressure drops when the
compressor shuts o
ff
.
The connections are loose or leaking
(
fi
ttings, tubing, etc.).
The drain valve is loose.
The check valve is leaking.
Check all the connections with soapy water
and look for bubbles. Tighten any loose
conections until the leak stops.
Tighten the drain valve.
Take the compressor to a service center.
WARNING:
Do not disassemble
check valve while
air is in tank - empty
the all the air out
of the tank before
dissasembly.
There is excessive
moisture in the air
discharge.
There is excessive water in the air tank.
The humidity is high.
Drain the tank to remove water.
Move the compressor to an area of less
humidity or use an air line
fi
lter to reduce
moisture discharge in the tank.
