Truck air compressor troubleshooting: Simple solutions

Continuous usage and the course of time can often make air compressors go faulty. However, most of these issues can be solved with the help of basic tools and minimal steps. In this article, we shall discuss some of the common issues truck air compressors go through, along with simple solutions. Read below to know more.

Truck air compressor troubleshooting

Below are the five most common air compressor problems

1. Constantly leaking air compressor

Solution: Frequent leakages in air compressors are one of the most common problems. If your air compressor is going through something similar, the first step is to check what exactly the problem is. When you shut off the air compressor on its full charge, and you notice the gauge dropping, there is definitely an air leak.

To solve this issue, you can tighten up the couplers wherever leakage is taking place. Check the leakage by covering the connections with soap foam, as leakage is where the bubble starts to appear. Make sure to check the tank valve as well because leaks can also take place when they fail to shut completely.

2. The compressor failing to start

Solution: First things first, make sure that your power cord is not disconnected or the power switch is not deactivated. If your air compressor still fails to turn on, there isn’t enough air pressure in it. Compressors fail to turn on when the cut-in pressure is not in proportion to the amount of air pressure in the tank; ensure the cut-in setting on the pressure switch is at the right level.

3. Broken compressor fan

Solution: If the compressor fan of your air compressor has broken down, replace it with a better quality and durable fan. Check the compressor handbook for a list of the part number and matching dimensions before choosing a new fan. Measure the original fan’s dimensions and hole diameter if you can’t find it. The number of blades and the direction of airflow are important considerations since they affect the compressor’s performance and make.

4. Inadequate flow

Solution: If your air compressor is taking longer to build air pressure or trips every now and then due to overheating, understand that the filter is obstructed by foreign particles (dust mostly). You can resolve the issue by removing the filter housing from the intake pump and running it again. If your air compressor starts to function smoothly, it infers that the filter was being obstructed by dirt and dust particles. You can clean it by placing it under running water for a minute.

5. The intake filter broke down

Solution: As the intake filter is responsible for filtering out the impure particulates from the incoming air, it is an essential component of the air compressor. It is quite a fragile component of an air compressor as it physically protrudes from the rest of the device. Fortunately, it is also one of the easier components that can be replaced manually. Make sure that you find a filter that fits your machine and has the same thread size and roughly the same portal size and diameter.


We hope that the above-stated steps help our readers to fix their faulty air compressors easily; however, if the problems continue to persist, it is always a better idea to call for repair and service from a trained technician.
