4 Reasons Why Your Aircon Switch On & Off By Itself

Having automated aircon switching on and of by itself? So, it’s another day in the smothering weather, and you’re looking forward to getting relief from the extreme heat – maybe getting a nap or something. Halfway through your snooze, you suddenly feel the air around you getting stuffier. You reluctantly wake up, and realize, oh, the air-conditioner has switched off by itself. Times like this can get extremely frustrating, so, let us walk you through the possible reasons, and you’ll see how to avoid or solve these problems.

Timer

Before delving into the more complex terms, let us first check the more straightforward possibilities. Ask around to find out if anyone in the house has programmed your air-conditioning unit’s timer to switch on and off at specified times of the day. For example, in some offices, the management switches off the building’s air-conditioning systems towards the end of the day, as part of energy-saving initiatives, while at home, someone might have set it that way for convenience’s sake.

Compressor Problems

Check if your compressor is clean. A dirty compressor can lead to overheating, leading to a circuit trip and shutdown until the air-conditioning unit reboots itself. In cases like this, you need to remove the coil, and if clean it if it is dirty. Sometimes, this may be due to a worn out compressor. Call a professional to help replace it with a new one.

Condenser Problems

Aircon condensers are used in devices that transfers cool air to another location. It is an essential part of air-conditioning units because it cools vapors coming from the compressor. When an air-conditioning unit switches on and off by itself, it may be due to a dirty or blocked condenser. To resolve these issues, you can clean the condenser coil and fins, or remove any unwanted debris.

Defective Thermostat

A thermostat works like this. It senses and helps your air-conditioning unit regulate and maintain your room’s temperature. If the thermostat senses that your room is at your desired temperature, it will keep it that way. If it senses otherwise, it will prompt your air-conditioning unit to either increase or decrease the room’s temperature.

Suppose the thermostat senses wrongly that the room has reached the optimal temperature or is too cold. In that case, it will shut off by itself, leaving you positively melting in that stuffy environment. Check if you’ve adjusted the thermostat correctly or if it is an unfortunate case of defectiveness.

If all these fail, it may be time to schedule a service call. If you current air con is ancient, why not get a brand new one? This may save you more money in the long run. Remember, regular checks and self-maintenance can help target problems before they escalate saving you much money and time!
