Common Reasons Your Aircon Is Not Cooling


Aircon Not Cold Picture

It’s a common question we hear from homeowners in our hot and humid Singapore, “Why isn’t my air conditioner cooling my home?”. We’ll guide you troubleshoot this annoying problem. To do this, the following causes below will help to narrow down the reason of the problems


Reason 1 - Air Filter

If the air filter is clogged, air cannot flow properly through the air conditioner. This greatly reduces the cooling capacity of the air conditioner. In addition, if the air filter is clogged, the evaporator coils will frost over. To remove debris from the air filter, try cleaning the filter. If it is not possible to clean the air filter, replace it.


Reason 2 - Condenser Coils are Dirty

The condenser coils dissipate the heat as the refrigerant passes through the coils. If the condenser coils are dirty, they won’t be able to dissipate the heat as effectively. As debris builds up on the coils, the air conditioner will become less efficient, causing the air conditioner to work harder to cool down. If the coils are significantly dirty, the air conditioner will not be able to maintain the proper temperature, and the compressor will run continuously in an attempt to cool the room. Check the condenser coils to determine if they are dirty. If the condenser coils are dirty, clean them.


Reason 3 - Compressor

The compressor might be defective. However, this is not usually the case. Before replacing the compressor, be sure to check more commonly defective components—particularly the overload protector and the compressor capacitor. If the compressor is defective, it should only be replaced by a licensed technician.


Reason 4 - Thermostat

The thermostat monitors the temperature of the air. When the air temperature rises above a set point, the thermostat activates a switch to provide power to the fan and compressor. If the thermostat is defective, the thermostat may not cool properly. To determine if the thermostat is defective, set the air conditioner to cooling and then use a multimeter to test the thermostat for continuity. If the thermostat does not have continuity while the air conditioner is set to cooling, replace the thermostat.


Reason 5 - Thermistor

The thermistor is a sensor connected to the control board that detects the temperature of the air. The resistance value of the thermistor changes in conjunction with the air temperature. If the air temperature rises, the resistance value will decrease. To determine if the thermistor is at fault, use a multimeter to test it for continuity. If the thermistor does not have continuity, or if the resistance of the thermistor does not change with a change in temperature, replace the thermistor.


Reason 6 - Control Board

The control board regulates the voltage to the compressor motor and the fan motor. If the control board fails, other components will not function properly or will not work at all. Control boards are often misdiagnosed; make you sure check more commonly defective parts before replacing the control board. If you are certain that all of the other components are working properly, replace the control board.


Reason 7 - Temperature Control Thermostat

The temperature control thermostat is a sensor which monitors the temperature of the air and activates a switch to provide power to the fan and compressor when the air temperature drops below a set point. If the thermostat isn’t working, the air conditioner will cool continuously or won’t cool at all. To determine if the temperature control thermostat is defective, use a multimeter to test it for continuity. If the thermostat does not have continuity, replace it.


Reason 8 - Temperature Control Board

If the temperature control board is defective, the fan motor and compressor will not get power. Control boards are often misdiagnosed; make sure you check other air conditioner parts before replacing the temperature control board. If you are certain that all of the other components are working properly, replace the control board.


Reason 9 - Run Capacitor

The run capacitor is connected to the compressor with electrical leads. If the run capacitor burns out, the compressor will not run. To determine if the run capacitor is burned out, test the capacitor using a multimeter. If the capacitor does not have continuity, replace it.


Hiring a Professional

When your air conditioner needs more than regular maintenance, hire a professional aircon service technician. Our well-trained aircon technician will find and fix problems in your air conditioning system.
