Porter Cable Air Compressor Common Problems

Air compressors are not the most common of features in a woodworking shop, although they do come in handy on job sites to power nailers and in painting around the house.

But air compressors did not make our list of “Must-Have” tools for the woodworking beginner.

Key Points:

  • We know that water is the enemy of wood.  Now we know that humidity is the cause of many air compressor system problems.  Start there when troubleshooting.
  • Check for leaky air compressor tanks on your Porter Cable model.  Check the hose, too.  These can be common air compressor problems and will result in diminished PSI.  Use the soapy water test – if bubbles develop, you have a leak to fix.
  • If it won’t start, check the obvious first – electrical power or a disconnected power cord.  Do not always immediately assume it is something major.

Still, they are handy to have around, and there are a ton of options both in brand name and features, as well as overall power.  There are plenty of brand names and air compressor types to choose from. 

Today we’re taking a look at Porter Cable models and examining some common problems associated with them.

However, we want to be quick to say there is nothing inherently wrong with Porter Cable air compressors or Porter Cable in general.  All air compressors eventually develop problems, and the Porter Cable Air Compressor is no different.

What To Do If Your Porter Cable Air Compressor Will Not Build Air Pressure Beyond 40PSI

There are a few things you can do if your air compressor will not build pressure past 40 psi:

  1. Check for leaks. The most common reason why an air compressor will not build pressure is because of a leak. Check all of the connections in the air compressor, including the hoses, valves, and fittings. If you find a leak, tighten the connections or replace the parts as needed.
  2. Check the oil level. If the oil level in the air compressor is low, it can cause the compressor to overheat and not build pressure. Check the oil level and add oil as needed.
  3. Check the air filter. If the air filter is dirty, it can restrict the flow of air into the compressor and prevent it from building pressure. Clean or replace the air filter as needed.
  4. Check the pressure switch. The pressure switch is a safety device that shuts off the compressor when the pressure reaches a certain level. If the pressure switch is defective, it can prevent the compressor from building pressure. Check the pressure switch and replace it as needed.
  5. Check the valves. The valves in the air compressor control the flow of air into and out of the compressor. If the valves are defective, they can prevent the compressor from building pressure. Check the valves and replace them as needed.

If you have checked all of these things and your air compressor still will not build pressure past 40 psi, you may need to take it to a qualified technician for further diagnosis and repair.

Here are some additional tips for troubleshooting an air compressor that will not build pressure:

  • Start by turning off the compressor and disconnecting the power. This will help to prevent you from getting injured if there is a problem with the compressor.
  • Once the compressor is disconnected, check for leaks. You can do this by spraying soapy water on the connections and looking for bubbles.
  • If you find a leak, tighten the connections or replace the parts as needed.  This includes the air hose, the compressor head, and the base of the compressor tank, all common areas for leaks to develop.
  • Once you have checked for leaks, turn on the compressor and see if it builds pressure. If it does not, check the oil level and add oil as needed.
  • If the oil level is correct, check the air filter and clean or replace it as needed.
  • If the air filter is clean, check the pressure switch and replace it as needed.
  • If the pressure switch is correct, check the valves and replace them as needed.
  • If you have checked all of these things and the compressor still will not build pressure, you may need to take it to a qualified technician for further diagnosis and repair.

What To Do If Your Porter Cable Air Compressor Won’t Start

  • The air compressor is making a loud noise. This could be a sign that the compressor is trying to compress water, which can damage the compressor.
  • The air compressor is not producing as much air pressure. This could be a sign that the water is interfering with the compressor’s ability to compress air.
  • There is water in the air line. The presence of water is a clear sign that you need to drain the air compressor tank and line.
  • The air compressor is leaking water. This is another clear sign that you need to drain the air compressor tank.

If you see any of these signs, you should drain the air compressor tank as soon as possible. Here are the steps on how to drain an air compressor tank:

  1. Turn off the air compressor and disconnect the power.
  2. Locate the drain valve on the tank. This is usually a small valve located on the bottom of the tank.
  3. Open the drain valve. You may need to use a wrench to open the valve.
  4. Allow the water to drain out of the tank. You can direct the water into a bucket or another container.
  5. Once the water has drained, close the drain valve.
  6. Reconnect the power and turn on the air compressor.

You should drain the air compressor tank every few months, or more often if you use the compressor in humid conditions. By draining the tank regularly, you can help to prevent damage to the compressor and keep it running smoothly.

Here are some additional tips for draining an air compressor tank:

  • Wear safety glasses when draining the tank. This will help to protect your eyes from the water and any debris that may be in the tank.
  • Be careful not to overtighten the drain valve. This could damage the valve or the tank.
  • If the water is dirty, you may want to clean the tank before refilling it. This will help to prevent the compressor from becoming contaminated.

By following these tips, you can safely and effectively drain the air compressor tank and keep your compressor running smoothly.

What To Look For On A Porter Cable Air Compressor Gauge

Porter Cable air compressors typically have two pressure gauges: a tank pressure gauge and a regulator pressure gauge.

The tank pressure gauge measures the pressure of the air in the compressor tank, while the regulator pressure gauge measures the pressure of the air that is being delivered to the air tools.

The tank pressure gauge is usually located on the front of the compressor tank, while the regulator pressure gauge is usually located on the regulator. The tank pressure gauge is typically marked in PSI (pounds per square inch), while the regulator pressure gauge is typically marked in PSI or BAR (bars).

It is important to regularly check the pressure gauges on your Porter Cable air compressor to make sure that the air pressure is within safe limits. The safe pressure limits will vary depending on the type of air compressor and the air tools that you are using.

However, most Porter Cable air compressors should not be operated at pressures above 150 PSI.

If the air pressure is too high, it could damage the air compressor or cause an explosion, and your attention should turn to the pressure release valve. If the air pressure is too low, the air compressor may not be able to provide enough power to operate air tools or other equipment.

If you notice that the air pressure is not within safe limits, you should turn off the air compressor and consult the owner’s manual for instructions on how to adjust the pressure. Start with the pressure release valve to de-pressurize quickly.

Humidity is the most common culprit when it comes to trouble-shooting air compressors, and Porter Cable models are no different.  Be aware, and when an issue develops, start there.  The above information will tell you what to look for.  

Keeping your compressor in a low humidity environment, perhaps even with a de-humidifier nearby, can keep a lot of problems from developing.
