So, you are frustrated as hell because you were all set to catch some best moments with your family in a cool room, but what? Your conditioner turned off itself?
I can feel you…
Well, the solution is simple:
This problem is known as “short cycling’’
In the short cycling, after turning on the air conditioner, it turns off by itself, after a short period (less than 15 min).
Before we dive into the solutions, let’s try to know why short cycling is bad.
Why is Short Cycling Bad?
Want to know why short cycling bad? Let’s get to it.
- Because a huge amount of power is required to turn on your air conditioner over and over again, which ultimately drives up your energy bills.
- You may not be achieving a comfortable temperature.
- This off/on cycle cause wear and tear on the mechanisms of your AC, thus ultimately shorting the life span of your AC.
- Short cycling should be fixed as soon as possible; otherwise, it may lead to expensive damage and an early replacement of your AC.
Now, we have a clear cut idea about why short cycling is bad. But we still don’t know the reasons behind short cycling. Let’s move forward to understand why your air conditioner turns off by itself.
Reasons Behind Why the Air Conditioner Turns Off by Itself
If your AC turned off by itself, it might have one of the following reasons:
Sometimes the malfunction of the thermostat may lead to short cycling. The malfunctioning of a thermostat is due to damaged wiring of the thermostat or some other electrical problems.
Lack of enough airflow through AC
Sometimes the blockage of airflow may overheat your AC components, which ultimately leads to turning off your AC.
The blockage of air is due to a Dirty air filter. If the air filter of your AC is covered with dirt, it blocks the airflow.
Blockage of the condensate line
Your AC absorbs moisture from your home’s air and drains out via a pipe.
Sometimes condensate pipe is blocked by some dirt that may lead to condensation backs into the drain pan. If the level of water reaches up to a certain level, it switches off your AC.
Oversized air conditioner
An oversized AC cools your home rapidly and turned off by itself. Too fast cooling is bad because it drives up energy bills, increased humidity, and more hot and cool spots in your home.
Installation of a thermostat in a bad location
If the location of the thermostat is near a window or under the AC vent, then the thermostat fails to detect the exact temperature of your home. In this case, call an expert to relocate the thermostat.
Lack of maintenance
Your AC requires regular maintenance at least once a year, or in some areas(such as in the desert)twice a year.
So now, you have understood why the air conditioner turns off by itself. Let’s get straight to the quick and easy solution to fix the problem.
Why Does My Air Conditioner Turn Off by Itself [6 Savvy Solutions]

You just need to move the thermostat to another place. Place the thermostat in the middle of the room or some other place where you can detect the cooling of your AC.
Note: Do not place the thermostat under the vent or near the window
Solution 3: Thermostat timer settings
If the major issue with your AC is “short cycling”. Don’t think that your AC is expired. There are many other reasons for short cycling. One of these reasons is that your AC thermostat may have timer settings. If your AC has timer settings for the thermostat, you can reset it in just 5 seconds.

It not only turn off your computer but also causes wear and tear to your AC. This wear and tear may shorten the life span of your AC. There are many reasons for air blockage but the main reason is the dirty air filter. Let see how can you ensure proper airflow through your HAVC system.
- Have a look at the air filter
- If it is dirty, replace the dirty air filter with new ones.
Solution 5: Clear and unblock the condensate pipe
As your AC absorbs moisture from your home’s air and drains out via a pipe. Sometimes dirt may clog the condensate pipe. Blockage of the condensate pipe may lead to short-cycling.
- Notice whether the condensate pipe draining the water out of your home or not
- If water is not draining out of your home
- Remove the cap from the T-shaped part of the condensate line
