Why Does My Air Compressor Keep Shutting Off?

If your air compressor keeps shutting off, there could be a few different reasons. Maybe the air compressor is getting too hot, the motor is overworked, or there is something wrong with the pressure switch. In any case, it's important to figure out what's causing the problem so you can fix it and get your air compressor back up and running again.

So in this article, I will discuss some things that can cause your air compressor to keep turning off so let's take a look at what causes the air compressor to behave like this.

Things That Causes An Air Compressor To Shut Off:

An air compressor is a device that pressurizes air in order to tools and other equipment. While compressors are built to last, they can run into issues and one common issue is the compressor shutting off. There are several reasons why this may happen, which include: a clogged air filter, too much oil in the system, incorrect voltage, and more.

By troubleshooting the problem, you can usually get your compressor up and running again. Below are some things that keep the compressor turning off and how you can fix it.

Having Low Oil Level:

One of the reasons for the air compressor shutting off is because of low oil level so It is important to check the oil level in the air compressor regularly and If the oil level gets too low, the air compressor will shut off so try to refill it as soon as possible.

Faulty Or Defective Pressure Switch:

If your air compressor keeps turning off, it may be due to a faulty pressure switch and this is a common problem that can be fixed. There are two main reasons why a pressure switch may fail.

First, the diaphragm can become damaged and need to be replaced, and second, the switch itself may become worn out and need to be replaced. If you're having this type of problem, then there are a few things that you can do in order to fix it. First, check the diaphragm for damage and replace it if necessary or you can clean or replace the pressure switch if it's dirty or worn out.

Safety Overload Protection Feature:

If your air compressor is shutting off, it's likely due to the safety overload protection. This is a safety feature that kicks in when the air compressor is overloaded and there are a few things you can do to fix this issue.

First, check to see if the air compressor is properly ventilated or not and if it's not, then the safety feature will stop the compressor and if the overload feature is defective then it needs to be replaced as it will keep the compressor from working as it will think the air compressor is overloaded and lastly, make sure that there isn't anything blocking the airflow to the air compressor. If you follow these tips, you should be able to fix the issue with your air compressor.

Not Enough Ventilation Or Ambient Temperature Too High:

As the temperature rises, your air compressor is working harder to maintain a set pressure and at some point, the air compressor will reach a critical temperature where it will automatically switch off to prevent damage. There are a few things that can cause your air compressor to overheat which will lead to shut off and the most common cause is ambient temperature.

If the temperature outside is too high, it can cause your air compressor to overheat and another common cause is blockages in the cooling fins or intake filters. These blockages prevent air from flowing through the compressor and allow heat to build up inside and if your air compressor keeps shutting off due to high ambient temperatures, there are some things that you can do to try and fix the issue.

First, is to make sure that there are no blockages in the cooling fins or intake filters, and try running the compressor in a cooler environment or in a ventilated area if possible.

Thermostatic Valve Not Working:

If your air compressor is switching off, it could be because the thermostatic valve is not working. This valve regulates the temperature of the air compressor, and if it’s not working, the compressor can overheat and shut off. If you think your thermostatic valve may be to blame, check to see if it’s dirty or damaged and if it is, you may need to replace it. You can do this yourself if you have experience in this field, or you can hire a professional to do it for you.

Once you’ve replaced the valve, make sure to keep an eye on the temperature of your air compressor and if it starts to get too hot, shut it off and let it cool down before restarting it. This will help prolong the life of your air compressor and prevent costly repairs down the road.

Not Doing Proper Oil Lubrication:

If an air compressor is not properly oiled, it will shut off. This can be a problem because an air compressor needs oil to lubricate its moving parts and without proper lubrication, the air compressor will overheat and eventually break down. To avoid this problem, make sure to regularly check the oil level in your air compressor and add more if necessary.

Faulty Temperature Switch:

Another reason for the air compressor to not work properly may be due to a faulty temperature switch. This can be a serious problem, as it can lead to overheating and damage to the compressor. If you suspect that your temperature switch is faulty, you should have it checked by a qualified technician.

Air Compressor Not Getting Enough Voltage:

If the voltage supply to the air compressor is low then the compressor will not get the required power for it to work hence it will keep shutting down and there are some things to check such as checking the volts at the outlet where the air compressor is plugged in and if the volts are low, you may need to plug the air compressor into a different outlet.

Also, check for any loose wires on the air compressor as loose wires can cause low voltage and make the air compressor turn off.

The Air Filter Is Dirty:

Having a dirty filter will not only reduce your air compressor efficiency but will also make it harder for it to work which can lead to the air compressor to switch off. A dirty air filter can restrict airflow and cause the compressor to overheat or not work properly. To clean the air filter, first, turn off the power to the compressor and rinse the filter with water and let it dry completely before putting it back in place.

Using The Wrong Type Of Oil:

If you're putting the wrong type of oil in the compressor then it's likely the reason for the compressor to behave like this. There are a few things to keep in mind when choosing the right oil for your air compressor. First, check the owner's manual to see what type of oil is recommended for your specific model and if you don't have the manual, you can usually find this information online or you can directly ask the manufacturer.

Frequently Asked Questions (FAQ):

Why Does My Kobalt Air Compressor Keep Shutting Off?

If your Kobalt air compressor keeps shutting off, it could be due to a variety of reasons. The most common reason is that the air compressor is overloaded which causes it to turn off.

Another reason why your Kobalt air compressor might keep shutting off is because the air filter is dirty and to clean the air filter, remove it from the unit and wash it with water and then let it dry before using it. If your Kobalt air compressor still keeps shutting off, you may need to take it to a professional for servicing or directly contact the manufacturer.

Why Does My Husky Air Compressor Keep Shutting Off?

If your husky air compressor keeps shutting off, there are a few possible reasons. One of the most common reason is that the air compressor is overheating. The air compressor has a built-in thermal overload switch that shuts off the compressor when it gets too hot and another possible reason is that the air pressure in the tank is too high. The pressure switch turns off the compressor when the tank pressure reaches a certain level. Finally, if the air filter is dirty, it can restrict airflow and cause the compressor to shut off. If the problem doesn't go away then I would advise you to contact the original manufacturer.

Conclusion:

Above are some of the things that make an air compressor to shut off and if you have checked all of the above things but still can't figure out the problem then I would recommend you to directly contact the manufacturer about it and also some air compressor can be defective which can cause them to not work properly. If this guide was helpful to you then kindly share it and have a great day.
