Signs of a Bad Air Compressor
Air compressors are used for a variety of applications, ranging from inflating car tires to powering air tools in workshops. If your air compressor isn’t working right, it can be a frustrating experience. Knowing some of the common signs of a bad air compressor can help you troubleshoot the issue more quickly and get your compressor running again.
Unusual Sounds
One of the tell-tale signs that your air compressor might be in need of service is when it starts producing unusual sounds. These may be anything from a faint clicking sound too loud knocking and banging. If you are hearing any type of sound that doesn’t usually come from your air compressor, then it’s best to have it inspected as soon as possible.
It’s also worth checking for any type of foreign object that might have gotten lodged in the motor itself or the air filter, which can cause strange noises. Make sure you get all debris removed from these areas before running your compressor again.
Finally, make sure all fittings are properly connected and there are no leaks anywhere in the system. Any leakage or poor fitting connection can cause banging, shaking, and rattling sounds in an otherwise well-functioning machine.
Leaks
Leaking is one of the more obvious signs that you have a bad air compressor. Air pressure leaks out and creates a noticeable sound, and will cause the pressure gauge to slowly drop when in use. Check all couplings, hoses, and other components while it’s running to identify any leaks. If you detect compressed air blowing anywhere other than through the tool you’re using it could be something as simple as a loose connection or damaged hose.
Low Pressure
When the output pressure of an air compressor drops below the designed level, it is often a sign that there is something amiss. Low pressures can be caused by a number of issues, and it’s important to maintain your machine in order to prevent problems. Causes for low pressure might include:
- Issues with the regulator or pressure switch settings. Incorrect patching between the two can cause low or high pressures.
- A faulty air intake valve or piston seals due to wear and tear over time, allowing air out of the system before it is compressed properly.
- The motor or motor capacitor is malfunctioning, causing less power to go into the system and therefore a reduction in compressed air output pressure levels.
- Clogged aftercoolers and filters that reduce airflow, resulting in low-pressure levels lower than designed parameters
- Oiled rotary screw compressors that have degraded too much over time start producing a lower amount of compressed air and pressure output than normal due to poorer compression levels being met within their cylinders during each compression cycle portion of their process sequence operations run.
It’s important to take care of any signs of malfunction as soon as possible to ensure your machine runs at optimal performance levels and keeps producing safe amounts of compressed air as designed!

High Pressure
If the air compressor is running at a higher pressure than it should, it could be a sign of a potential problem. If the pressure switch is faulty, it can cause the compressor to over-pressurize and release too much air into the system. High pressure can also be caused by other components such as an incorrectly sized suction line or even a faulty check valve.
If you notice that your Air Compressor is running at a higher pressure than usual, there are some things you can do in order to determine if this is caused by something else.
High Pressure can be dangerous if left unchecked so if you do detect abnormally high pressure in your system don’t hesitate to call in professional help from trained technicians who will be able to accurately diagnose and repair any issue with your unit quickly and safely.
Troubleshooting
Your air compressor can run into several issues which can cause it to become bad. Troubleshooting your air compressor is important in order to identify and resolve the problem. This section will focus on different ways to tell if your air compressor is bad, so you can take the necessary steps to fix it.
Check the Pressure Switch
Checking the air pressure switch is one of the key elements of troubleshooting an air compressor. It is located near the top of the tank on most compressors and contains a bellow with a contact point that signals when the air pressure reaches the set level.
If you cannot hear the pressure switch clicking on and off, it may be an indication that there is a problem with it or with its connection to the power source. You can test for this by unplugging and reconnecting after double-checking all connections and wiring for any issues.
If reconnecting does not fix the issue, it might be time to consider replacing your old pressure switch with a new one. Be sure to select a new switch rated for your compressor’s CFM (cubic feet per minute) rating, as well as its proper amperage draw at full load and idle positions.
Check the Intake Filter
If your air compressor is not running properly, the first thing you should do is inspect the intake filter. The intake filter is a small screen or air inlet designed to keep dirt and particles from entering or damaging the machine.
When inspecting the filter, make sure that it is clean and not blocked with dirt or dust. You can usually remove this with a damp cloth or vacuum cleaner and reapply it securely back into place. If there is too much dust buildup.
If the filter looks damaged, you should contact a professional for inspection and guidance on how to replace it properly. Failing to replace a broken or damaged intake filter can allow dirt particles into the system and cause further damage down the line.
Check the Motor
If the motor of an air compressor fails, it will no longer be able to produce pressurized air. Before attempting to repair the motor, you should check for basic problems such as a blown fuse or low voltage.
First, make sure that the power cord is properly plugged in and that the outlet is working by plugging in a different device. If the outlet is functioning properly, look for distant or obvious signs of any electrical damage to the power cord that could have caused a disruption in power transmission.
Finally, inspect the motor itself for visible signs of wear and tear such as cracked insulation or loose wiring connections within its housing unit. If any physical damage is detected then it’s best to consult a technician before attempting repairs as motor repair can be complex and require specialized tools and knowledge.
Maintenance and Repair
Air compressors are integral machines for any shop or workspace. Regular maintenance and repair of an air compressor are essential for the smooth running of the machine and to check for any potential issues. With timely maintenance, you can identify any problems with the compressor that may be causing it to not function properly. In this section, we’ll look at how to identify any issues with your air compressor, and what you can do to repair them.
Clean the Intake Filter
Ensuring that the intake filter of your air compressor is clear and clean is an essential part of keeping your unit in constant operation. If the intake filter becomes clogged, the unit will spend more energy attempting to compress more air than it can easily handle, leading to extra strain on components like belts, valves, and pistons.
When inspecting your intake filter for clogs or blockages:
- Start by removing both ends of the protective housing containing the intake filter element
- Ensure that no dirt or debris has been trapped around seal surfaces or in any cracks or gaps between component parts
- Visually inspect the entire surface area of an exposed intake filter media for excessive dirt buildup
- Clean any parts found with a soft brush or cloth
- Use a vacuum cleaner with a brush attachment to remove the remaining dirt buildup
- Once you are confident that all surfaces are clean and free from obstructions, reassemble all component parts securely
- Check gaskets for proper seating before replacing cover plates to ensure proper sealingAdjust the Pressure Switch
To troubleshoot your air compressor, you will need to start by adjusting the pressure switch.
First, ensure that the power cord is unplugged, and then locate the pressure switch. To adjust it, first, check the cut-in or start-up setting which is typically labeled “Cut” or “On” (this will vary between models). You should turn this knob until you meet the required performance requirements.
Next, adjust the cutout or stop setting labeled “Off” (which may vary between models) so that your compressor does not shut off prematurely or run continuously without enough padding past the running capacity required for optimal operations. Again, refer to your manual for a suggested acceptable range for PSI given in bar(s).
Finally, when all settings are complete make sure to tighten any connections with a wrench and plug back in the power cord before testing out your adjustments further during regular use of the air compressor.
Repair or Replace the Motor
Before you decide to repair or replace a motor, it’s important to identify the underlying cause of the malfunction. If a mechanical failure is to blame, then determining whether salvaging the current motor or investing in a new one is warranted can depend on several factors. Above all else, professional advice will help you determine what is best for your particular situation.
When repairing air compressors, repairs should always be performed by trained technicians who have experience with such motors and follow the manufacturer’s specifications. Finally, consider your own preferences in replacing or repairing the faulty motor; whether you want an exact replacement or some additional features that may improve performance levels.
Conclusion
In conclusion, the condition of your air compressor can have a major effect on its performance. You can look for several signs to indicate if it’s time for repairs or replacement. Be sure to pay attention to any strange sounds, foul odors, leaking, and an increase in electricity bills as these are all signs that your air compressor might be broken. Additionally, consider hiring a professional to inspect the air compressor if you’re still unsure of its condition.
