LG AC Ice Formation Repair in Chennai
Ice builds up on the coil or pipes, choking airflow and cooling.
When frost or solid ice forms over the evaporator coils of your LG split AC, it restricts airflow and causes water to drip into your room rather than cooling the air. On LG’s Dual Inverter models, ice buildup often triggers smart error codes like CH 38 (refrigerant shortage) or CH 24 (high pressure/restricted flow). Ignoring coil icing forces the dual-rotary compressor to work under extreme load, potentially leading to liquid slugging and total compressor failure during hot Chennai months.
Common Symptoms of Ice Buildup on LG Air Conditioners- Solid frost or thick ice layers visible behind the LG front panel louvers or on outdoor brass valves.
- Water overflowing from the indoor unit's drain pan onto walls and flooring.
- Diminished airflow output even when the fan speed is set to maximum on the LG ThinQ remote.
- System repeatedly shutting down with CH 38 or CH 23 error codes displayed on the indoor panel.
- Warm air blowing from the unit while the copper suction pipe outdoor is completely frozen over.
- Low Refrigerant (R32 / R410A Leakage): Micro-punctures in the evaporator coil drop operating pressure, causing coil temperatures to plunge below freezing.
- Clogged Dual Inverter Dust Filters: Dust accumulation blocks intake airflow over the cooling coils, preventing heat exchange and causing ambient moisture to freeze.
- Faulty Indoor Blower Motor or Capacitor: Slow fan rotation reduces warm air passage over the evaporator, freezing trapped condensation instantly.
- Blocked Drain Line or Damaged Expansion Valve: Stagnant water tray backups or metering device restrictions destabilize coil temperature gradients.
- Controlled Defrost & Diagnostic Scan: We safely thaw the ice without damaging LG’s fine aluminum fins and run self-diagnostic checks for active CH error codes.
- Airflow & Blower Restoration: Complete high-pressure jet cleaning of the evaporator coil, anti-bacterial filters, and cross-flow blower wheel.
- Nitrogen Leak Testing & Brazing: Locating microscopic gas leaks along copper joint welds using electronic leak detectors, followed by precise silver brazing.
- Vacuuming & Precise Gas Top-Up: Pulling the system down to deep vacuum levels before recharging factory-specified R32 or R410A refrigerant by weight.
- Post-Repair Thermal Validation: Verifying sub-cooling/superheat values and airflow temperature differentials to ensure zero re-icing.

AC Ice Formation on other brands
Frequently asked questions
Why is ice forming on my LG split AC indoor unit?
Ice forms primarily due to restricted airflow from dirty air filters/coils or low refrigerant levels caused by a gas leak. When airflow drops or refrigerant pressure falls, the evaporator coil temperature drops below 0°C, freezing atmospheric moisture.
Is it safe to run my LG AC while ice is freezing on the coils?
No, running an icing LG AC can cause liquid refrigerant to flood back into the dual inverter compressor, leading to permanent mechanical failure. Turn off the AC immediately and allow the ice to melt naturally before calling a technician.
How long does it take to fix an LG AC ice buildup issue?
A typical service takes 1 to 2 hours. This includes safely defrosting the unit, performing a high-pressure jet wash, testing for gas leaks, and topping up refrigerant if required.
