Making Positive Business Choices

There are many reasons why air compressors fail. If you're aware of the common causes, you can prevent your next failure and you'll be able to wait longer before you must hire an air compressor repair service.

Air Leaks

You will want to check for air leaks periodically. Your air compressor might restart to deal with the sudden drop in pressure. However, most of the components that can lead to leaks in your air compressor can be repaired easily. 

If the air compressor will not start, this is usually due to there not being enough air pressure. This is usually the result of air leaks. Also, inspect the cut-in section on the pressure switch and make sure that it is adjusted properly. 

Electrical Problems

Your air compressor might have electrical problems that are causing it to fail to draw the electricity it needs. There are some mistakes you can make that can lead to a blown fuse such as using an extension cord. If your compressor trips a breaker at startup, this could be the result of air trapped over the pistons as a result of a faulty unloader valve.

Lack of Maintenance

If your air compressor has clogged air filters or doesn't have enough lubrication, the air will not remain clean and there will be a buildup of debris and damage to the internal components. The air will also not be clean. The system will wear out more quickly if it is not properly maintained due to friction between the internal components. 

Oil might accumulate in the airlines. This can harm the air compressor because some parts of the air compressor use different types of oil than others. The wrong type of oil can work its way into the wrong part of the compressor.

You may also develop flow problems if there is an obstructed intake filter media-element. You may notice that the compressor takes longer to build air and the motor will overheat and stop functioning. 

The Compressor Refuses to Stop

When the compressor won't stop running, this is usually the result of a defective pressure switch or a defective pressure release valve. These are essential components and it's important that you hire a repair technician to make sure that they function properly. However, when you know what problems to look for, you'll know when to call air compressor repair services. Look for a local technician to help with yours.
