[Easy fix] Why does my air compressor keep shutting off?

Numerous folks are curious about why their air compressor keeps shutting off. The response is: a short cycle will likely cause your air compressor to shut off unexpectedly. This indicates that the compressor is overheating, and if it begins and stops too frequently, it will damage. 

To sustain the compressor running as long as possible, it’s imperative to deal with the short cycle. Therefore, continue reading if you’re serious about learning more about the causes of the compressor shutting off and how you can solve this issue.

Why does my air compressor keep turning off

The Air compressor shut off early for many issues. Here I pick up some points for you.

  • High temperatures may cause your air to shut off.
  • The oil level is low.
  • The Air compressor keeps shutting off for dirty oil AC
  • A damaged temperature switch can turn off your compressor.
  • If the oil lines become dirt.
  • Air constantly leaks from the oil tube.
  • Indicator problem of the read valve, so that your air compressor shuts off at 40 psi.
  • Low voltage may occasionally also force the compressor to shut down.
  • Craftsman air compressor keeps shutting off for overheating.

Fix it so that the air compressor never shuts off

The compressor may shut off due to short cycling, but a few other things could have an impact. Here are a few justifications for taking preventative action.

  1. Feel the Leaks

A leak in the system is the most apparent cause of a compressor’s short cycling. Ensure all connections are secure and the air hose is free of any holes because even a minor leak can make the air compressor cycle more frequently.

Spraying a soapy water solution on the fittings and hoses will allow you to taste the leaks. If bubbles appear, you know you’re leaking.

  1. Look through the valve settings.

The quantity of air entering the compressor is controlled via valves. The compressor may short cycle if the gates are not correctly set. By rotating the compressor’s knob, you can change the valves.

  1. Examine the overload prevention mechanism.

This compressor safety function is in charge of turning the compressor off when it detects an increase in temperature. Even when there isn’t an overload, a malfunctioning overload prevention system will restrict the compressor from turning on.

Disconnecting the overload protection mechanism and starting the compressor will allow you to test it. You must replace the overload protection mechanism if the compressor begins to run.

  1. Suitable Lubrication

The compressor may overheat and have short cycling if it is improperly oiled. Removing the oil cap and inspecting the level can determine the lubrication level. More oil needs to be added if the story is low.

  1. Pressure switch malfunction

Air compressors employ pressure switches to protect the machinery by turning it down when a predetermined pressure is reached. And the gas air compressor keeps shutting off for maximum air pressure.

To make sure your pressure switch is operating correctly:

  • Make particular the pressure setting is accurate by checking it.
  • Examine the switch contacts for damage and clean them as necessary.
  • Verify the voltage at the switch and make any necessary corrections.
  • If the button is broken, replace it. For example, if your Makita air compressor keeps shutting off, just release the button.
  1. Cleaning the dirty air filter

When the filter is blocked with dust and grime, the compressor won’t get enough air to work correctly. To maintain the air filter clean and clear of particles, you should clean it frequently.

  • Remove the compressor’s air filter.
  • Use fresh water to rinse the filter.
  • Let the filter dry naturally.
  • Install the air compressor once more.
  1. Adding oil to fix the low level of oil

The working parts of the air compressor cannot be adequately lubricated when the oil level is too low. And in this case, you will notice your diesel air compressor keeps shutting off. It is crucial to monitor the oil level and add oil as needed.

Adding oil:

  • Cut the compressor’s power.
  • Clean up the vicinity of the oil cap.
  • Dispatch the oil cap.
  • Fill the compressor with oil.
  • Put the oil lid back on.
  • Connect the compressor.

8. Use the correct oil

Incompatibility between the oil and the compressor might increase wear and tear and shutdowns in the long run.

Before adding oil to the machine, it’s vital to consult the owner’s manual because different models of air compressors require different types of oil. If you don’t have a handbook, ask the maker what kind of compressor oil you should use.

You can reach out to me too. I’ll lead you. This is an important consideration that shouldn’t disregard. If the incorrect oil is used repeatedly, the air compressor may finally stop working.

9. Provide suitable ventilation:

  • An ample room must be left around the compressor to allow adequate airflow.
  • You should use a fan to move air around the compressor.
  • Contact the manufacturer about a compressor cooler if the outside temperature is too high.

10. Working thermostatic valve Blockage:

The thermostatic valve controls the compressor’s temperature. The compressor may overheat if the valve is not functioning correctly. You can test the thermostatic valve by unplugging the compressor and removing the valve. If you can open the valve by blowing through it, it is broken and needs to be replaced.

To check the thermostatic valve’s functionality:

Check the valve for obstructions or dirt.

It would be best if you cleaned the valve.

Verify the oil lines for blocks or dirt.

If necessary, clean the oil lines.

Make sure the valve is adjusted correctly.

11. Add voltage

The compressor won’t have enough power to work correctly whenever the voltage drops at a specific point. Please check the volts at the outlet where the compressor is put to determine the voltage. You might need to add a voltage stabilizer if the low voltage.



Q1. Why does my AC compressor shut off within a few seconds?

Thermostat issues, incorrect thermal settings, dirty oils, conditioner size, refrigerant leaks, and damaged capacitors can all cause your AC compressor to turn on and then shut off.

Q2. Why does my air compressor keep turning off?

When your air compressor shuts off as soon as it turns on, trapped air is probably over the cylinders. Please turn off the tank, remove it from the power supply, and empty the tank of all air to check for this issue.

Q3. What is the most common cause of air compressor failure?

 Leaks in a system frequently cause failures of air compressors. These leaks may develop as components deteriorate with time. When the tank is full of air, and the compressor is turned off, you can tell whether the compressor is leaking air if the pressure gauge shows a decline in pressure after the compressor has been turned off.

Q4. How do you reset an air compressor?

Air compressors can power various time-saving gadgets, from auto maintenance to carpentry and home painting. Your compressor works best when the proper pressure is maintained.

Final Thought

In short, the answer is a short cycle is the most frequent reason your air compressor shuts off abruptly. This shows that the compressor is starting and stopping too frequently, which causes overheating and damage. However, your compressor is not damaged, so don’t worry.

Some of the most frequent explanations for your compressor possibly shutting off have been discussed. I’m hoping that this advice will assist you in identifying the issue and fixing it so that your compressor can function once again.
