When aircon switches off by itself or switches on and off by itself, it suggests some problems with your aircon.
They can be due to:
Your remote control is the first thing you troubleshoot. Sometimes you will be surprised that you are able to resolve the issue simply by resetting the remote control. The reset button is usually not easily visible to us and you may need a paper clip to activate it. If this fails to rectify the issue, ask yourself when was the last time you cleaned or serviced the aircon. You may need to service your aircon if it is due to dirty fan coil.
Dirty Fan Coil
Sometimes the problem of “Aircon Switches Off by Itself” may just go away after you give it a thorough cleaning. This is because clogged air filter, dirty fins or some other obstruction to the airflow may result in auto shut down of your aircon’s Fan Coil. If this works, good for you. If it does not work, it suggests a more complicated underlying issue and you will have to call upon the aircon technician to troubleshoot the problem.
Electronic Circuit Board Problem
It could be the malfunctioning of electronic circuit board within the aircon’s Fan Coil. If this is the issue, a replacement of circuit board is required and it should be performed by the aircon technician.
The compressor is the engine behind the cooling mechanism of aircon and this may be the culprit for the “Aircon Switches Off by Itself” problem. It may have worn out or overheated and therefore initiated the shutting down of the aircon.
The refrigerant in your aircon system has to be maintained at an acceptable level for the aircon to work properly. Once it falls below a certain level, it will lose its cooling ability to the extent of shutting down the aircon system. As such, any leakage of refrigerant should be resolved immediately.
