Steps To Fix A Porter Cable Compressor Regulator

Below, I will walk you through the steps I took to fix my Porter Cable air compressor regulator and do it in an easy-to-understand way. Therefore, grab your tools, and let’s start–

  1. Turn Off and Unplug The Porter Cable Air Compressor

Before you begin any work, ensure the machine is switched off and detached from the power source. And this will prevent any potential accidents or injuries while working on the regulator.

  1. Release Air Pressure From The Compressor

Next, release any air pressure that may be trapped in the compressor. And it can be done by opening the air valve on the regulator or turning on the compressor and allowing it to run until the pressure drops to zero.

  1. Locate The Regulator And Remove It From The Air Compressor

Once the pressure is released, locate the regulator on the air compressor. It’s usually located near the pressure switch and the pressure gauge. Then remove the regulator by unscrewing it with pliers or a wrench from the compressor.

  1. Disassemble The Regulator

Carefully disassemble the regulator by removing the screws or bolts that hold it together. And write everything down in the order in which you can remove the parts to ensure you reattach the regulator correctly.

  1. Inspect The Parts And Identify The Faulty Ones

Inspect the regulator’s components, including the diaphragm, springs, and valve components. After that, check for any signs of damage that can reason the regulator to malfunction.

  1. Replace The Faulty Parts

If you identify any faulty parts, it’s time to replace them. You can purchase replacement parts from a Porter Cable dealer or an authorized retailer. Make sure to choose the correct replacement parts that match the model and type of your Porter Cable air compressor.
