Signs your LG aircon needs an outdoor-fan check
These symptoms can involve the outdoor fan motor, but they can also come from the blade, condenser airflow, capacitor, wiring or fan driver.
The outdoor fan does not start or stops during cooling
The motor may be locked or unpowered, but the capacitor, driver output and position feedback must also be checked.
The outdoor unit becomes hot, noisy or repeatedly trips
Poor fan operation can raise heat and pressure, but the condenser, blade and compressor circuit also need checking.
An outdoor fan, lock or overcurrent code appears
A LG fan, driver or feedback code identifies the circuit to test. It does not prove that the motor needs replacement.
Examples of LG systems we check
These are common examples, not a complete list. We also assess other LG systems after checking the indoor and outdoor model labels.
LG Multi V outdoor units reporting CH67 fan-lock faults
LG Multi V outdoor units reporting CH77 or CH79 fan overcurrent and position-sensor faults
LG Multi V outdoor fan IPM and heatsink circuits reporting CH106 or CH193, confirmed from the exact unit number
Don't see your LG model?
Send photos of the indoor and outdoor model labels, plus the error code or a short video of the symptom. We'll confirm the right diagnostic starting point and outdoor fan motor service scope before arranging the visit.
It may not be the outdoor fan motor
Before ordering a model-specific outdoor motor, we check three problems that can create the same stopped-fan, noise or overcurrent symptoms.
Condenser or ledge airflow restriction
A fouled outdoor coil, obstruction or poorly ventilated ledge can raise heat and pressure while the fan motor still operates correctly.
Fan blade or bearing load
A cracked, loose or rubbing blade can create noise, vibration, slow running and motor overcurrent.
Capacitor, PCB or fan-driver fault
The motor may be healthy but unable to start because its supply or electronic drive is weak, missing or in protection.
LG error codes related to outdoor fan motor problems
Your LG error code helps us identify where to start. It does not prove that the outdoor fan motor needs replacement. Open the group that matches where the code appeared.

What happens during a LG outdoor fan motor check
The aim is to give you a clear diagnosis and a sensible repair decision, not an automatic parts quote.
Send us the model and symptoms
Share the LG indoor and outdoor model numbers, any error code, which rooms are affected and what happened before the fault.
We test the likely causes
We inspect the condenser, fan blade and movement, then test supply, capacitor where fitted, connectors, fan-driver output and position feedback before selecting a motor.
You receive the finding and quote
We explain what failed, whether the correct part is available and whether repair or replacement is the better use of your money.
We repair and test the system
After approved work, we run the LG system through a full cycle and confirm that the original symptom or error has cleared.
Is LG outdoor fan motor repair worth it?
It depends on the confirmed fault, system age, parts availability and the condition of the rest of the aircon.
Parts and timing
The correct LG outdoor fan motor, blade, capacitor or fan-driver part is model- and fan-number-specific. We confirm the motor code, drive type and distributor lead time before you approve work.
Our recommendation
Outdoor-fan-motor repair is usually sensible when the motor or feedback circuit is confirmed, the correct part is available, and the condenser, fan driver and compressor remain healthy; an older system with board, compressor or multiple major faults needs a closer repair-versus-replacement comparison. LG systems commonly have a service life of 8–12 years. For a system over 10 years, major component failures favour replacement. Parts for older ArtCool models may be hard to source, and efficiency loss adds to the running cost of keeping the unit.
If replacement is the better option, we can compare the repair quote with a suitable new system instead of asking you to keep repairing an uneconomical unit. See our aircon system replacement process.
Why diagnosis matters on LG aircon
LG outdoor-fan codes can point to the motor, blade, capacitor, connector, harness, fan driver or position feedback. Testing the heat-rejection and drive path helps avoid replacing a working motor.
A LG outdoor fan motor fault we check carefully
LG Multi V codes CH67, CH77 and CH79 distinguish fan lock, overcurrent and position feedback, while CH106 and CH193 identify fan-IPM current and heatsink protection. The outdoor unit and fan number are confirmed before repair.

Workmanship warranty
We stand behind the repair we carry out, and we are straight about the part of the cover we do not set ourselves.
Labour
30-day labour warranty. If the same fault returns from the repair we did, we come back and the labour is on us, with no second diagnosis fee.
Parts
Parts follow whatever warranty the distributor sets for that component, so the term varies by part. We tell you the coverage before you approve the quote.
