LG Aircon Error Code – What Singapore Users Should Know
Aircon Error Code
Modern air conditioners are smart machines. Instead of completely shutting down when something goes wrong, they show an aircon error code to warn you early. If you’re using an LG unit from LG Electronics, those blinking lights and strange codes actually help prevent costly damage — if you understand them correctly.
In Singapore’s hot and humid weather, ignoring these warning signs often leads to aircon not cold, aircon water leaking, or even compressor failure. This guide explains what the codes mean and when to call professional aircon servicing Singapore experts like letscool aircon and Services Singapore.
1. Why LG Aircon Error Codes Appear
Your aircon constantly monitors temperature, pressure, sensors, and airflow. When readings go beyond safe limits, the system stops and shows an error to protect its components.
Common reasons include:
- Dirty filters blocking airflow
- Refrigerant problems requiring aircon gas top-up
- Faulty thermistor sensors
- Drainage clog causing aircon water leakage
- Electrical PCB issues
Many homeowners first notice the issue when the aircon light is blinking repeatedly. This blinking pattern corresponds directly to an error code — basically, your airconis asking for help before damage worsens.
- Daikin Aircon Light blinking
- Mitsubishi aircon light blinking
- Midea aircon light blinking
- Panasonic Aircon Light blinking
Regular aircon general servicing prevents most of these alerts.
2. Most Common LG Aircon Error Codes in Singapore Homes
Here are the codes technicians encounter most frequently:
CH01 / CH02 – Sensor Fault
The temperature sensor cannot read properly.
Symptoms: aircon not cold, sudden shutdown.
Usually fixed during professional aircon repair Singapore or replacement of aircon spare parts.
CH05 – Communication Error
Indoor and outdoor units cannot communicate.
Possible causes
- Wiring loose
- PCB board fault
- Power fluctuation
Needs technician diagnosis — not DIY safe.
CH10 – Indoor Fan Motor Problem
Airflow stops, and cooling drops quickly.
You may notice:
- Weak airflow
- Noise
- aircon not cold
Often solved with aircon compressor servicing and motor repair.
CH 38 – Low Refrigerant
Very common in Singapore due to long operating hours.
Symptoms
- Cooling reduced
- Ice forming
- Higher electricity bills
Requires leak check and aircon gas top up — not just refilling blindly.
CH34 – Overheating Compressor
Serious warning. Turn off immediately.
Without quick aircon repair Singapore, compressor burnout may occur — the most expensive repair in any system.
3. What Blinking Lights Are Trying to Tell You
Many homeowners panic when they see aircon light blinking, but it’s actually helpful.

Different blinking speeds = different issues:
- Slow blink → maintenance required
- Fast blink → system protection triggered
- Continuous blink → critical failure
This usually means your unit urgently needs:
Dirt buildup is the #1 cause of error codes in Singapore’s dusty + humid environment.
4. Problems You Should Never Ignore
Ignoring an LG error warning often turns a small fix into a big repair.
Aircon Not Cold
Usually due to:
- clogged coil
- low refrigerant
- dirty blower wheel
A proper aircon servicing visit restores performance quickly.
Singapore's humidity produces heavy condensation.
Blocked drainage causes overflow.
- Daikin Aircon water leaking
- Midea Aircon water leaking
- Mitsubishi Aircon Water Leaking
- Panasonic Aircon Water Leaking
Solution:
Professional flushing + aircon steam wash
Constant Error Code Restart Loop
Repeated shutdown damages electronic boards.
Best solution:
Sign an aircon service contract to prevent recurring faults.

How to Prevent LG Error Codes Permanently
Prevention costs far less than repair. In Singapore, aircons run daily, so maintenance matters.
Recommended schedule:
- Every 3–4 months → aircon general servicing
- Every 6–8 months → deep cleaning
- Yearly → full inspection
Professional maintenance includes:
- Coil cleaning
- Drain flushing
- Electrical check
- Refrigerant pressure test
- aircon compressor servicing
Companies like LetsCool Aircon and Services Singapore also offer aircon promotion packages and long-term aircon service contract plans that significantly reduce the risk of breakdowns.
Final Thoughts
An LG aircon error code is not a disaster — it’s an early warning system. Whether it’s aircon not cold, aircon water leaking, or a persistent aircon light blinking, acting quickly prevents expensive failures.
Most issues are solved with routine cleaning or minor repairs, but ignoring them leads to compressor damage or full replacement. Regular maintenance, proper aircon installation in Singapore, and timely servicing keep your system efficient in Singapore’s extreme climate.
If your aircon displays a code, don’t reset repeatedly — diagnose it early. Your comfort and wallet will thank you.
