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
□
The tank has sufficient pressure.
□
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.
□
The motor is too hot and the
thermal overload is open.
□
Loss of power or overheating.
□
The pressure switch is bad.
□
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.
□
The fuse size is incorrect or the
circuit is overloaded.
□
The gauge wire or the length of
extension cord is wrong.
□
The check valve or the unloader is
defective.
□
The voltage is low.
□
A poorly ventilated room is
causing the motor to overheat.
□
The gauge wire or the length of
extension cord is wrong.
Solution
□
The compressor will turn on when the tank
pressure drops to cut-in pressure.
□
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.
□
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.
□
Check the power supply and any extension cord
meet the gauge and length requirements of this
compressor.
□
Replace the pressure switch.
□
Check the voltage from the power supply with a
voltmeter.
□
Use the correct wire gauge and length extension
cord.
□
Take the compressor to an authorized service
center.
□
Take the compressor to an authorized service
center.
□
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.
□
Use the correct wire gauge and length extension
cord.
□
Take the compressor to an authorized service
center.
□
Check for proper voltage using a voltmeter.
□
Move the compressor to a well-ventilated area.
□
Check for proper gauge wire and cord length.
