TROUBLESHOOTING

PROBLEM
The compressor
does not run.
The motor hums,
but does not run or
runs slowly.
The fuses blow or
the circuit breaker
trips repeatedly.
The thermal
overload protector
cuts out repeatedly.
POSSIBLE CAUSE
1. Loss of power or overheating.
2. There is no electrical power being
supplied to compressor or the power
switch is in the OFF position.
3. A fuse has blown at the power
supply.
4. A breaker has tripped at the power
supply.
5. Thermal overload open.
6. The pressure switch is bad.
7. Tank is full of air.
1. The voltage from the power supply is
low.
2. The gauge wire or the length of
extension cord is wrong.
3. The motor winding is shorted or
broken.
4. The unloader or check valve is
defective.
1. The fuse size is incorrect or the
circuit is overloaded.
2. The gauge wire or the length of
extension cord is wrong.
3. The unloader or check valve is
defective.
1. The voltage from the power supply is
low.
2. A poorly ventilated room is causing
the motor to overheat.
3. The gauge wire or the length of
extension cord is wrong.

CORRECTIVE ACTION

1. Check for proper use of extension
cord.
2. Check to be sure the compressor is
plugged in and the power switch is
in the ON position.
3. Replace the fuse at the power
supply.
4. Reset the breaker at the power
supply and determine why the
problem happened.
5. First unplug the compressor and
wait until it becomes cool. Motor
will restart when cool.
6. Replace the pressure switch.
7. Compressor will turn on when tank
pressure drops to cut-in pressure.
1. Check the voltage with a voltmeter.
2. Use the correct wire gauge and
length extension cord.
3. Take the compressor to a service
center.
4. Take the compressor to a service
center.
1. 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.
2. Use the correct wire gauge and
length extension cord.
3. Take the compressor to a service
center.
1. Check the voltage with a voltmeter.
2. Move the compressor to well-
ventilated area.
3. Check for proper gauge wire and
cord length.
