Living in Singapore means you rely heavily on air conditioning. But what happens when your Samsung aircon suddenly stops cooling? This can be frustrating, especially during the hot and humid months. Let’s break down the possible causes and what you can do if your Samsung aircon is not cooling.
Check the Temperature Setting
Sometimes, the cooling issue is as simple as the wrong mode or temperature setting. Ensure that:
- The mode is set to “Cool.”
- The temperature is set lower than the current room temperature.
- The fan speed is appropriate.
Also, check if “Dry” or “Fan” mode is activated instead of “Cool.”
Dirty Air Filter of Your Samsung Aircon
Singapore’s dusty environment can clog your air filters quickly. A dirty filter blocks airflow, making the cooling weak or uneven.
What to do:
- Open the front panel of the indoor unit.
- Remove the filter and wash it with lukewarm water.
- Let it dry completely before reinstalling.
Clean your filter every 2 to 3 weeks for best performance.
Low Gas Pressure or Refrigerant Leak
If your aircon is running but the air isn’t cold, there might be a refrigerant issue. This is common in older units or if there’s been poor maintenance.
Signs of low refrigerant:
- Cooling takes too long.
- Ice builds up on the indoor unit.
- Hissing sound near the pipes.
What to do:
Call a certified aircon technician in Singapore. Only licensed professionals can refill refrigerant and check for leaks.
Dirty Condenser Coil
The condenser coil in the outdoor unit of your Samsung aircon plays a key role in heat exchange. If it’s covered in dirt or debris, your unit will struggle to cool effectively.
Common signs:
- Weak cooling even on full blast.
- Unit overheats or shuts down suddenly.
What to do:
Hire a technician to clean the outdoor condenser coil. In landed properties or low-floor HDBs, this is often easier to access.
Faulty Compressor of Samsung Aircon
The compressor of your Samsung aircon is the heart of the cooling system. If it fails, the entire cooling process stops.
Possible signs:
- The aircon hums but doesn’t cool.
- Outdoor unit is silent or making strange noises.
- Circuit breaker trips often.
What to do:
Get a professional diagnosis. Compressor repair or replacement can be costly, and your technician may suggest replacing the whole unit if it’s too old.
Does the Samsung Unit have Thermostat or PCB Board Issues?
Sometimes the cooling issue lies in the internal electronics. A malfunctioning thermostat or printed circuit board (PCB) can stop the unit from detecting room temperature or controlling the compressor properly.
Symptoms include:
- Room remains warm even after hours of use.
- Aircon turns on and off randomly.
You’ll need an experienced technician to run diagnostic tests and repair or replace the affected part.
Wrong Installation or Poor Airflow
If your aircon was not installed correctly, it may not distribute air efficiently. Obstructed airflow due to poor placement or blocked vents can also affect cooling.
Common causes:
- Indoor unit installed near a heat source.
- Furniture or curtains blocking vents.
- Outdoor unit has poor ventilation.
What to do:
Inspect the surroundings and ensure both indoor and outdoor units have open space for airflow.
When Should You Call a Technician?
If basic troubleshooting doesn’t work, it’s time to call a professional. Always choose a licensed aircon servicing company in Singapore. They can:
- Check for gas pressure issues
- Deep clean the system
- Replace damaged parts
- Provide accurate diagnosis
FAQ
Why is my Samsung aircon not blowing cold air at all?
This can be due to wrong mode selection, low refrigerant, or a failed compressor. Try adjusting the mode first. If that doesn’t help, get a technician.
How often should I clean my Samsung aircon filter in Singapore?
Every 2 to 3 weeks. Frequent cleaning helps the unit work efficiently in Singapore’s dusty and humid environment.
Can I refill the refrigerant myself?
No. Refrigerant handling requires special equipment and certification. Always hire a professional.
Does a blinking light mean there’s a fault?
Yes. Samsung aircons often use blinking lights to signal a problem. Refer to the user manual or get a professional diagnosis.
Should I replace my aircon if it’s not cooling well?
If it’s over 8–10 years old and repair costs are high, replacing the unit may be more cost-effective.
