Air Compressor Pressure Switch Wiring Diagram

Are you having trouble with your air compressor pressure switch wiring diagram? Don’t worry, you’re not alone. Many people find this process confusing and overwhelming, but it doesn’t have to be. In this article, we’ll break down the steps for you, so you can get your air compressor up and running in no time.

What is an Air Compressor Pressure Switch?

Before we get started on the wiring diagram, let’s first understand what an air compressor pressure switch is. Essentially, this switch controls when your compressor turns on and off. When the pressure in your compressor’s tank drops below a certain level, the switch activates, and the compressor turns on to refill the tank. Conversely, when the tank reaches a certain pressure, the switch deactivates, and the compressor turns off.

The pressure switch is an essential component of any air compressor and is typically located near the motor. Now that we understand what it is let’s move on to the wiring diagram.

Wiring Diagram

The first step in the wiring process is to turn off your air compressor and unplug it from the power source. Safety always comes first, and we want to ensure we’re not putting ourselves in danger.

Once you’ve done that, you’ll need to locate your air compressor pressure switch. As previously mentioned, it’s usually near the motor, and you should be able to identify it easily.

Now it’s time to connect the wires. You should have three wires to work with: a ground wire, a power wire, and a load wire. The ground wire is typically green or bare and should be connected to a metal part of the compressor.

The power wire is usually black, and the load wire is usually red or white. The power wire should be connected to your power source, while the load wire should be connected to the motor.

Once you’ve connected all three wires, you’re ready to turn your air compressor back on and test it out. If everything is working correctly, your compressor should turn on and off as needed when the pressure in the tank drops below or reaches a certain level.

Common Issues

While wiring your air compressor pressure switch should be a straightforward process, there are a few common issues that people run into. Here are some of the most common issues:

The Compressor Won’t Turn On

If your compressor won’t turn on after you’ve wired it, there are a couple of things you can check. Firstly, make sure that the pressure switch is set to the correct setting. Secondly, check that your power source is working correctly.

The Compressor Won’t Turn Off

If your compressor won’t turn off, you may have a problem with your pressure switch. Check that it’s wired correctly, and if that doesn’t work, you may need to replace the switch.

The Pressure is Too Low/High

If you find that the pressure in your tank is not at the correct level, you may need to adjust the pressure switch. Refer to your compressor’s user manual for instructions on how to do this.

Hopefully, this article has been helpful in guiding you through the process of wiring your air compressor pressure switch. Remember to always put safety first, and if you’re unsure about anything, consult a professional.
