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.
