Top 10 Common Aircond Problems in Malaysia and How to Fix Them
In Malaysia’s hot and humid weather, a fully functional air conditioning system is not a luxury—it’s a necessity. But just like any electrical appliance, airconds are prone to problems over time, especially without regular maintenance.
In this article, we’ll cover the 10 most common aircond problems faced by Malaysian households and businesses, along with possible solutions and tips on when to call a professional.
1. Aircond Not Cooling Properly
Problem:
Your aircond is running but the room is still warm or takes too long to cool.
Possible Causes:
- Dirty air filters
- Low refrigerant gas
- Blocked condenser coils
- Malfunctioning compressor
Fix:
Clean the filters and check for visible blockages. If the problem persists, get a professional technician to inspect the gas level and compressor.
2. Aircond Leaking Water (Indoor Unit)
Problem:
Water is dripping from your aircond unit and may even be staining your walls.
Possible Causes:
- Clogged drainage pipe
- Dirty evaporator coil
- Improper installation (no slope for water flow)
Fix:
Flush the drainpipe and clean the coil. If you’re unsure, call an aircond service provider to prevent water damage.
3. Aircond Making Loud or Strange Noises
Problem:
You hear buzzing, rattling, or grinding noises during operation.
Possible Causes:
- Loose fan blades or screws
- Worn-out motor
- Debris stuck in the outdoor unit
Fix:
Turn off the system and inspect for debris. Do not ignore the noise—early servicing can prevent serious damage.
4. Aircond Light Blinking
Problem:
A blinking LED on the indoor unit, usually accompanied by cooling failure.
Possible Causes:
- Error code due to a fault
- Low refrigerant
- PCB or sensor issue
- Indoor-outdoor unit communication error
Fix:
Refer to your unit’s manual or call a technician. Each blink pattern represents a specific issue.
5. Aircond Smells Bad
Problem:
Foul or musty smell when the aircond is turned on.
Possible Causes:
- Mold or bacteria in the filters or coils
- Stagnant water in drain pan
- Clogged filters
Fix:
Schedule a chemical cleaning or deep aircond cleaning. Regular maintenance prevents bacterial growth.
6. Aircond Automatically Turns On/Off
Problem:
The aircond starts or stops randomly without user input.
Possible Causes:
- Faulty thermostat
- PCB board issue
- Voltage fluctuation
Fix:
Reset the unit or check the thermostat. If the issue continues, contact a qualified service team.
7. Aircond Gas Leak / Low Gas
Problem:
Cooling is weak or non-existent, with hissing sounds or ice buildup.
Possible Causes:
- Leak in refrigerant pipe
- Aging system
- Improper installation
Fix:
Only a licensed technician can detect leaks, recharge the gas (R22, R32, or R410A), and seal the leak safely.
8. Aircond Remote Not Responding
Problem:
Remote doesn’t change settings or turn on the unit.
Possible Causes:
- Dead batteries
- Faulty remote sensor
- IR sensor failure in the unit
Fix:
Try new batteries and clean the sensor. If the problem continues, use a universal remote or call for IR sensor replacement.
9. Outdoor Unit Not Running
Problem:
Indoor unit runs, but the outdoor unit doesn’t turn on.
Possible Causes:
- Tripped breaker
- Blown capacitor
- Faulty contactor or compressor
Fix:
Check the power supply. If the outdoor fan or compressor fails to start, you’ll need an expert to replace the faulty parts.
10. Aircond Trips the Breaker or Power Supply
Problem:
Switching on the aircond causes a power trip or fuse blowout.
Possible Causes:
- Short circuit in wiring
- Overloaded circuit
- Faulty capacitor or motor
Fix:
This is a serious electrical issue. Turn off the power immediately and contact an aircond technician to inspect and repair the unit safely.
Prevention: Regular Maintenance is the Key
