Most Common Husky Air Compressor Issues

Generally speaking, Husky air compressors are known to be durable and a great choice for all of your compressed air needs. These compressors canyourrk under various conditions and with multiple applications.

Additionally, they aren’t known to break down under stress. However, they do have their quirks. Some of these issues are common and you may end up facing one or more of them during its lifetime.

Pressure Building Issues

This is an issue that you can have with an air compressor. You may find that the pressure isn’t building up in the tank.

The pressure may not be building due to a faulty pressure valve. Most people can remove the pressure valve, clean it off, and screw it back in to achieve a working status again. However, some may not be so lucky and this will require a new pressure valve.

Additionally, it could be a problem with a gasket. If you find the generator is only giving out small amounts of pressure, this could be due to a bad gasket between the low and high-pressure compartments. Fortunately, you can easily replace the gasket.

Faulty Regulator

Another common issue that Husky air compressors have is air intake problems. With this issue, you may find that your compressor isn’t achieving the proper air intake as it should. This could be an easy fix.

You should make sure that the air inlet of the compressor isn’t blocked and that it’s not clogged. The air intake should be pointed towards open-air from there the proper amount of air can be taken in. 

If this was the issue, great! You won’t need to buy a part. If this didn’t help, check the air filter and ensure that it’s always clean. If you think it’s clogged, you can replace the filter. It’s generally an inexpensive fix.

Voltage Sensitivity

If it’s becoming an issue, you can invest in a voltage stabilizer. This will keep the main circuit board or ECU from shorting out or becoming damaged. The voltage stabilizer you choose should be compatible with the voltage ratings of the compressor.

Faulty Pressure Release Valve

Earlier we mentioned Husky air compressors having an issue holding pressure. There is also the occasional issue of the compressor holding too much air and building extreme amounts of pressure.

This is due to a faulty pressure release valve. If this valve fails to release the pressure in the tank, the tank then becomes too pressurized and the motor will stop running. 

If this becomes an issue, you will need to shut the compressor down and don’t run it again until you replace the pressure valve. Running it without the replacement could damage the compressor. 

How To Perform Repairs

Now that you have your replacement parts, you should know how to properly repair your Husky air compressor. 

Pressure Regulator Knob

To perform this fix, you will need to remove all remaining air from the compressor before you do anything.

Next, unscrew the top piece. There should be two screws on each side of the regulator. Once you pull that cover off, you will need to use an adjustable wrench to twist off the hose and pressure regulator knob. 

After you have taken off the regulator knob, install the new regulator. You can put some plumbers tape on the threads of the knob to ensure secure fit as well. You may need to take off the gauges from the old regulator if your new part didn’t include one. You can put them on the new regulator as long as they still work. Ensure all connections are tight and test your compressor. 

Pressure Release Valve

The safety valve is responsible for keeping the pump from over pressurizing the tank. There’s a spring that will wear out over time. You can purchase a new valve and replace it on your own.

You can do this by first depressurizing the tank. You can open the drain on the tank to do so. 

After that is done, you will need to remove the manifold cover. You can then take a wrench and remove the safety valve. Simply twist the new valve on and make sure it’s tight. You will then put the manifold back on and you’re good to go. 

O-Ring Replacement

You will want to replace an O-ring if you find that air is leaking from the regulator. You can remove the regular knob by twisting it counterclockwise once you remove the manifold cover. Depending on your model, it could be one screw or two. 

Once you remove the regulator knob, you will find a spring inside of it. This fits over a small cone inside the cap. Set the cap aside. There’s a plastic place inside of the area where the pressure regulator knob was. Deep inside of the area, you can reach in with a pair of needle-nose pliers. Don’t force it or you may break it. 

Around the outside of the plastic piece you just pulled out is a rubber O-ring. This O-ring may not be securely seated on the plastic piece.

Make sure you have the proper size O-ring and put some compressor-safe lubricant on it and put it back around the plastic piece. The O-ring goes on a certain way, so make sure the flat side goes inside towards the regulator. The O-ring should be tight without debris blocking the seal. 

Once that’s done, put everything back together and ensure that the regulator is working and the tank is holding pressure. 

Filter Replacement

Each filter is located in a different spot depending on which make and model air compressor you have.

The filter is going to be easy to change. Locate the area where the filter is housed and take off the cap. Once the cap is off, the filter will be exposed. It’s not a large filter. Simply remove the old filter, clean the inside of it with a clean cloth, and place the new one in.


We hope that our Husky air compressor replacement parts guide has helped you get your compressor up and running like the day you unboxed it.

Remember, each model will require its corresponding part, so it’s best to make sure the replacement parts fit your compressor. You can look up parts by using the model number of the compressor.
