5 Common Reasons Why Your Aircon Turns On and Off Frequently

When you buy yourself a nice aircon, you should always be aware of the malfunctions, countermeasures, and solutions to the problems of the aircon. If you are looking for answers to such questions, you are certainly at the right place. 


Now, turning on and off the aircon is a common safety measure of the aircon to avoid damage. In the following, I am giving you five of the most common reasons for the frequent turning on and off of the aircon. These reasons are;

1. Leakage of the Refrigerant

The very first reason for the frequent turning on and off of your aircon is the leakage of the refrigerant from your air conditioner. Refrigerant is the chemical that is responsible for the constant cooling of air in the environment. 


When this refrigerant starts leaking, it means the cooling system of the aircon is compromised and the aircon turns off. Even if you turn it on again, it will turn off automatically.

2. Thermostat Issues

The thermostat is the part of the aircon that shows you the temperature of the air being thrown by the air conditioner. Problems with the thermostat could also lead to frequent turn-offs of your aircon.

These issues include bad placement of the thermostat or any malfunction related to the thermostat itself. This is because the thermostat could show the wrong temperature and mess up the functioning of the air conditioner. So, keep track of it as well.

3. Clogging of Air Filter

The air filter is the component of the aircon that filters the incoming cooled air and passes it on. The constant filtering of air can cause the air filter to clog and could malfunction the air conditioner.

In such a situation, the air conditioner takes countermeasures and turns itself off until the issue is resolved. So, watch out for it as well.

4. Issues With Aircon Capacity

Air conditioners have a certain capacity at which they can operate and give their optimal output. If the usage exceeds this capacity, it could lead to dangerous breakdowns in the air conditioner.

As a countermeasure, the aircon turns off whenever the usage exceeds the capacity of the aircon. Also, never keep trying to turn it on under the same user because it would certainly destroy the air conditioner.

5. Problems with the Condenser

The condenser is the most crucial component of the aircon that helps in the cooling of the air. Now, it could malfunction as well and expose the aircon to great risks. The malfunctions of the condenser could include freezing, clogging, getting dirty, etc. These issues could cause the air conditioner to take countermeasures and turn it off to avoid damage.


In conclusion, turning on and off the aircon is a common safety measure for the aircon against malfunctions. So, you do not need to worry whenever your aircon turns off or on automatically. Also, you should always try to keep your air conditioner free of any problems. 

The best way to achieve this is to constantly get the maintenance of your aircon done. The most optimal period would be 2 months. So, always get your air conditioner’s maintenance done on time.
