Troubleshooting
Problem
Possible Cause
Solution
The compressor does not run.
□
The tank has sufficient pressure.
□
The compressor will turn on when the tank
pressure drops to cut-in pressure.
□
There is no electrical power being
supplied to compressor or, the
power switch is in the OFF
position.
□
Check to be sure the compressor is plugged in
and the power switch is in the ON position.
□
A fuse has blown at the power
supply.
□
Replace the fuse at the power supply.
□
A breaker has tripped at the
power supply.
□
Reset the breaker at the power supply and
determine why the problem happened.
□
The motor is too hot and the
thermal overload is open.
□
Disconnect the compressor from the power
supply and allow the motor to cool for several
minutes. The thermal overload will automatically
reset after the compressor has cooled.
□
Loss of power or overheating.
□
Check the power supply and any extension cord
meet the gauge and length requirements of this
compressor.
□
The pressure switch is bad.
□
Replace the pressure switch.
The motor hums, but does not
run or runs slowly.
□
The voltage from the power
supply is low.
□
Check the voltage from the power supply with a
voltmeter.
□
The gauge wire or the length of
extension cord is wrong.
□
Use the correct wire gauge and length extension
cord.
□
The motor winding is shorted or
broken.
□
Take the compressor to an authorized service
center.
□
The unloader or check valve is
defective.
□
Take the compressor to an authorized service
center.
The fuses blow or the circuit
breaker trips repeatedly.
□
The fuse size is incorrect or the
circuit is overloaded.
□
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 circuit,
disconnect other electrical appliances from circuit
or operate compressor on its own branch circuit.
□
The gauge wire or the length of
extension cord is wrong.
□
Use the correct wire gauge and length extension
cord.
□
The check valve or the unloader is
defective.
□
Take the compressor to an authorized service
center.
The thermal overload protector
cuts out repeatedly.
□
The voltage is low.
□
Check for proper voltage using a voltmeter.
□
A poorly ventilated room is
causing the motor to overheat.
□
Move the compressor to a well-ventilated area.
□
The gauge wire or the length of
extension cord is wrong.
□
Check for proper gauge wire and cord length.
