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 unplugged 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 off.

The connections are loose or leaking 
(fittings, 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. 
 
 
 
 

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 filter to reduce moisture discharge in the tank.

Air is leaking from the compressor.

The hose connection is loose or 
improperly sealed.
The air hose is broken or damaged.

Ensure connections are sealed with 
thread sealing tape and tightened.
Replace the air hose.

The compressor runs continuously

The tank drain valve is open.
The pressure switch is defective.
The usage is excessive.

Ensure the tank drain valve is closed.
Take the compressor to a service center.
Decrease the amount of tool run-time; the compressor is 
not large enough to supply the air requirement of the tool.

The compressor vibrates.

The compressor mounting bolts are loose. Tighten mounting bolts.

The air output is lower than normal. The inlet valves are broken.

The connections are leaking.

Take the compressor to a service center.
Apply thread sealing tape to fitting and tighten.

   WARNING:

Do not disassemble check valve while 
air is in tank - empty the all the air out of 
the tank before dissasembly.
