How to Repair Your Air Compressor in 3 Simple Steps

  1. Consistent power.
  2. Effective pressure controlling.
  3. Smooth flow of compressed air.

The air compressor repair works mostly relate to any of the three categories mentioned above. If you follow the logical path of troubleshooting, you can easily locate the problem in your air compressor and do the required repair-work in a simple manner.

However, there is always a risk of pressure tank rupturing when the repair work is of a complex nature. So, you need a professional technician to accomplish complicated repair tasks.

 

Tools Required

You are going to need the following things for air compressor repair:

  • Screwdriver
  • Wrench
  • Teflon plumber’s tape
  • Soapy water
  • Locking pliers

How to Restore Power

  1. Reset

You need to firmly plug the cord into the outlet, then, switch on the power. If you observe that the power is not restored, press the “Reset” button to reset the circuit breaker.

The “Reset” button is often present near the power cord attachment point, at the side of the compressor motor. It is round in shape and colored red (or black). If you see that the power is not restored, go to the next step.

  1. Check all connections

Ensure all connections are properly in place. If you find any loose cord, repair it then and there.

  1. Check the breakers

You may need to find the circuit breaker box and check for the tripped breakers. Each breaker has a small square box which indicates whether the breaker is tripped or not. Flip the breaker off, then turn it back on. If power is still not restored, go to the next step.

  1. Test the outlet

Now, you may need to test the outlet. Plug a small lamp or radio with the outlet to see if it’s working properly. If the outlet is working correctly, plug the cord of the air compressor into it to test it again. If the air compressor remains inactive, you should take it for professional servicing.

How to Build Pressure

  1. Charge your air compressor and find the air leakage

Detach hoses and tools from the power source and turn on your compressor for charging. Spray soapy water on and around the air compressor’s fittings. In this way, you can find out the air leakage which can be indicated by bubbling.

  1. Release the pressure

After finding the air leakage, locate the small pressure release valve present close to the air outlet. Pull the ring attached to it and release the pressure from the tank.

  1. Remove affected fittings

Take a wrench and hold the fittings from the air compressor that were bubbling actively. You can remove these fittings by turning them counterclockwise. To ensure safety, tape the threads of the fittings with Teflon tape.

  1. Thread back the fittings and test

After securing the threads with the tape, thread and tighten the fittings back into your air compressor using the wrench. Now repeat steps 1 and 2 to see further leakage. You may want to replace the fittings that are still leaking.

  1. Open the bleed valve

Put the compressor back on charging. Find the bleed valve which is available at the bottom of the tank. With the help of locking pliers, grip the valve and open it by turning clockwise.

  1. Blow out the air from the tank

Allow the air to blow out of the tank until you see that the condensation is dry. Now, tighten the bleed valve.

How to Adjust the Air Flow

  1. Remove the top and expose the two control screws

You need to remove the plastic shroud from the compressor’s top. Remove the screws using the screwdriver and lift off the cover to unleash the two pressure limiter screws:

  • The upper control screw controls the airflow when the compressor goes off.
  • The lower control screw is for controlling when the air compressor is turned on.

     2.  Adjust the pressure when the compressor goes off

Turn on the air compressor and note down the pressure setting as the air compressor goes off. If you need to adjust the pressure, use the upper control screw. The pressure can be increased by tightening the screw clockwise. To lower the pressure, you can rotate the screw counterclockwise.

  1. Adjust the pressure when the compressor comes on

To check the pressure at the time when the air compressor comes on, you need to pull the release valve first. To raise or lower the pressure, use the lower control screw. Put the cover back on top and tighten up all screws.
