TROUBLESHOOTING
The motor will
not run or start.
POSSIBLE CAUSE
PROBLEM
SOLUTIONS
The motor runs
continuously
when the
ON/OFF
switchis in the
ON position.
The regulator
does not
regulate the
pressure.
The power cord is not plugged in.
The on/off switch is in the O (OFF)
position.
The extension cord is the wrong wire
gauge or is too long.
The motor’s thermal overload
protection has tripped.
A fuse has blown or a circuit breaker
has been tripped.
The air tank pressure exceeds the
preset pressure switch limit.
The safety valve is stuck open.
Electrical connections are lose.
The motor, capacitor or safety valve is
defective.
The ON/OFF switch does not shut off
the motor when the air compressor
reaches the cut-out pressure and the
safety valve activates.
The compressor’s capacity is not
enough.
The regulator or its internal parts are
dirty or damaged.
Plug the power cord into a grounded outlet.
Set the on/off switch to the ON position.
Check extension cord information for the proper
wire gauge and cord length.
Turn the air compressor off, unplug the power
cord and wait until the motor has cooled down.
Plug in the power cord only after the motor has
cooled down, and wait at least 5 minutes to make
sure the thermal overload protector has
recovered.
Replace the fuse or reset the circuit breaker.
Verify that the fuse has the proper amperage.
Check for low voltage conditions.
Disconnect any other electrical appliances from
the circuit or operate the compressor on a
dedicated circuit.
The motor will start automatically when the tank
pressure drops below the cut-in pressure.
Clean or replace the safety valve.
Contact an authorized service center, or call
1-888-899-0146.

Set the ON/OFF switch to the OFF position. If the
motor does not shut off, unplug the air
compressor. If the pressure switch is defective,
replace it.
Check the air requirements of the accessory that
is being used. If it is higher than the CFM (Cubic
Feet per Minute) and pressure supplied by the
compressor (page 2), a larger capacity air
compressor is needed.
Most accessories are rated at 25% of actual CFM
while running continuously.
Replace the regulator.
