Does your aircon keep shutting down on its own?
It can be frustrating—especially in Singapore’s heat.
But don’t worry. Let’s break down the possible causes and how you can fix them.
First, Why Does This Happen?
There are several common reasons your aircon might be turning off by itself:
Dirty air filters – Blocked airflow can cause overheating.
Thermostat issues – Your unit may be getting the wrong signals.
Faulty sensors – The aircon may think it’s cooler than it is.
Electrical problems – Loose connections can trigger safety shutdowns.
Refrigerant issues – Low gas can force the system to stop.

What Can You Do?
First of all, check your air filter. If it’s clogged, give it a clean or replace it.
Next, make sure your thermostat is working properly and set at a reasonable temperature.
However, if the issue continues, it’s best to get a professional to inspect the system.
Sometimes, the real problem lies inside the circuit board or compressor.
