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.

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.
