Does Your Compressor Need Repairs? 10 Warning Signs

By In Blog On February 22, 2017


Air compressors are an integral part of many industries. When your compressor stops working as efficiently as it should or stops working altogether, the problems can cause delays, necessitate expensive services, or even put your employees in danger. One of the best ways to prevent serious air compressor issues is to handle repairs as soon as they are needed.

In this blog, we list 10 warning signs that indicate that your air compressor needs to be inspected and may need to be repaired.

1. Breaker Tripped or Blown Fuses
Breakers trip or Fuses blow out when your electrical system becomes overloaded. When this occurs, you will not be able to use the compressor at all until the fuse is replaced or the breaker is reset. If the issue continues have an electrician check the electrical circuit. If the circuit is good then it may be another issue.

2. Excess Moisture at Point of Use
Compressing air produces condensate which must be removed. Check to see if the air receiver drains are working properly. If this is a manual drain then it needs to be drained on a daily basis. If it is an automatic drain it may be faulty. You may need to add a dryer and or filter to your system.

3. Excess Noise
Industrial air compressors are loud, but your unit should only make one type of noise that continues at a fairly consistent volume. If your air compressor suddenly becomes louder, there may be an issue with the compressor or motor. If the sound of the compressor changes to include rattling, humming, or screeching, you may have a loose or broken component that needs to be replaced.

4. Frequent Thermal Overload
If a compressor shuts down on thermal overload check for proper ventilation around the compressor. Clean any coolers. Reset the thermal overload. If this step does not eliminate the problem, consult with a technician. Additionally, if your compressor overheats often, it may need to be serviced.

5. Full Tank
Your air compressor tank should be emptied at the end of every work day. See 2 above. If this step is neglected, your tank may develop rust or other forms of corrosion. In cold weather conditions, a full tank could also freeze, warping the tank and causing leaks. If you suspect that the tank has been full for more than one work day, empty the reservoir and have a professional determine whether any damage has been done.

6. Low Flow
A healthy air compressor performs at about the same level every time it’s used. Any change in performance could indicate a system problem. Check to see if there is an excessive air leak in the system. Has additional equipment or demand been added? If nothing in the system has changed then the compressor may have internal problems such as worn piston rings or valves or faulty system.

7. Low Air Pressure
Low air pressure is one of the most common issues with faulty compressors. This decrease in pressure can make your unit impossible to use. In many cases, low air pressure is related to faulty controls. However, inadequate air pressure can also result from internal compressor wear or something as simple as slipped belts.

8. No Air Pressure
If your compressor has no air pressure at all, you most likely have a control problem. Check the controls for proper settings. If the problem persists, have a technician assess the compressor and controls.

9. Oily Air Discharge
Your air compressor needs oil lubricant to run correctly. Depending on the type of compressor some oil will carry over to the discharge. However, if the oil carry over has increased you may have internal or control issues. A trained technician can determine the cause of the oil carryover.

10. Unresponsive Power Switch
While you can troubleshoot many of the issues on this list to see if you can avoid calling in a repairman, you should schedule a service immediately if your unit doesn’t respond to the power switch. While power problems don’t always require complex repairs, you should leave them to a professional because these tasks have a high risk of electric shock.

If you notice any of these warning signs or a combination of these symptoms, have a technician evaluate your compressor as soon as possible. Prompt inspection and repair can save you money in the long run, since it prevents more costly problems and ensures that a faulty air compressor won’t slow your business down.
