AIR COMPRESSOR

TROUBLESHOOTING

PROBLEM

POSSIBLE CAUSE

POSSIBLE SOLUTIONS

Pressure drop in the tank.

Air leaks at connections.

Let the compressor build pressure in the tank, to 
the maximum pressure if possible. Brush soapy 
water on air connections and look carefully for air 
bubbles. Tighten leaky connections. If the problem 
persists, contact the seller for further advice.

The unloader valve leaks when 
the compressor is idle.

Unloader valve seal is defective.

Let the air in the air tank flow out until all the 
pressure is released. Then remove the unloader 
valve plug and clean the valve seal. If necessary, 
replace the seal and then reinstall all components.

The compressor stopped and 
does not start.

The thermal protector turned on because 
the motor is overheating.

Check that the main voltage corresponds to the air 
compressor specifications. An extension cord that 
is too thin or too long can cause a voltage drop and 
cause the motor to overheat.  

Excessive use (over 1 hour continuous use) can 
cause the motor to overheat  

Allow the motor to cool down.

Motor windings are burned out.

Contact Customer Support.

The motor does not start and 
makes a humming noise.

Capacitor is burned out.

Contact Customer Support

The motor does not start or starts  
slowly.

Low voltage supply to the motor.

Check that the main voltage corresponds to the air 
compressor specifications.  

An extension cord that is too thin or too long can 
cause a voltage drop.. Use heavy duty extension 
cords.  

Ensure that the air compressor is plugged into a 
fully functional power outlet

The compressor is noisy with 
metallic clangs.

Compressor head gasket or reed valve is 
damaged

Stop the compressor and contact the dealer.

The compressor does not reach 
the maximum pressure.

Compressor head gasket or reed valve is 
faulty.

Stop the compressor and contact the dealer.

The compressor doesn't seem to 
provide as much air as it did 
when new and/or the compressor 
cuts off within a much shorter 
time period.

The pressure switch needs adjusting.

Stop the compressor and contact the dealer.

The tank is full of water due to 
condensation.

 Open the drain valve and release the water from 
the tank.

The motor pump unit does not 
stop when the tank pressure 
reaches its maximum working 
pressure (125 PSI).

Pressure switch defective or needs 
adjusting.

Stop the compressor immediately and contact 
Customer Support.
