My Air Conditioner Turn Off By Itself-Best Guide

If your air conditioner keeps turning off by itself, you might be wondering why this happens and how to fix it. There are several reasons why this could be happening, including possible issues with the thermostat and the temperature of the room your unit is in.

I also faced the same problem because I was a beginner similar to you. But, by searching and doing some research, I got the issue resolved. This guide will teach you more about the reasons that your air conditioner might turn off by itself and some possible fixes that can keep it from happening again in the future.

My Air Conditioner Turn Off By Itself

Check if AC needs maintenance

Your air conditioner could be shutting off because it needs maintenance. Over time, dirt and dust can build up on the coils and cause the AC to work less efficiently.

In some cases, the AC may even turn off to prevent damage. If you think your AC needs maintenance, contact a professional for help.

Overheating issue

The air conditioner has a safety switch that is designed to turn the unit off when it begins to overheat. This is a preventative measure to keep the AC from sustaining further damage and potentially catching fire.

If your AC is turning off by itself, it’s likely because it’s not able to properly circulate air and is therefore overheating. To fix this, you’ll need to clean the filter and/or have a professional check for any blockages in the unit.

Check the thermostat settings

If your air conditioner keeps turning off by itself, it’s likely because the thermostat settings are incorrect. The most common reason for this is that the AC is set to cool mode instead of auto mode. In cool mode, the AC will turn off when the desired temperature is reached.

However, in auto mode, the AC will continue to run until the room reaches the set temperature and then cycle on and off to maintain that temperature. Another possibility is that the AC is set to a too high or too low temperature.

Again, in cool mode, the AC will turn off when it reaches the set temperature. But if it’s set too high, it will turn off and then back on again repeatedly as it tries to reach the higher setting.

It needs repair

If your air conditioner keeps shutting off, it may be time for a repair. There are several reasons why your AC might be turning off, including:
-The AC is too cold and needs to be thawed out
-There is a problem with the compressor
-The AC is overworked and needs a break
-There is an issue with the wiring
If you’re not sure what’s wrong with your AC, it’s best to call a professional. They will be able to diagnose the problem and get your AC up and running again in no time.

It may be blocked by furniture

If you have your air conditioner in a window and there is furniture blocking the AC, the air conditioner will turn off by itself. The reason for this is that the AC needs airflow to work properly.

If the airflow is blocked, the AC will overheat and turn off. To prevent this from happening, make sure to keep furniture away from your AC unit.


What problems do people face related to the same problem? Some of them are mentioned below.

Where is the reset button of the Air Conditioner is situated?

Start by looking for it on the exterior of the machine. It is typically red, visible, and located near the bottom edge. It is possible that the reset button is located inside the unit behind the service panel if there is no reset button visible from the outside.

How long does it take to rest an AC?

Once you have turned the power back on, you should sit tight for 30 minutes. Once this time period has elapsed, your system will be up and running again.

In short, your air conditioner turns off by itself to save energy. This is most likely happening because your AC unit is set to Energy Saver mode. In this mode, the AC unit will turn off when it reaches the temperature you have set on the thermostat.

Energy Saver mode is a great way to save money on your energy bill, but it can be a bit of a pain if your AC unit keeps turning off at inopportune times. If you find that your AC unit is constantly turning off, you may want to try setting the thermostat to a higher temperature.
