ADP73673403 Genuine Cross Flow Fan Assembly for LG Air Conditioners, Indoor Unit Barrel Fan Blower Wheel

ADP73673403 is a genuine LG cross flow fan assembly. Cross flow fans, also called barrel or tangential fans, are the long cylindrical fans used in the indoor head of LG split system air conditioners to draw room air across the coil and push it back into the room. The stock record doesn't list the matching models, so compare the part number with your LG parts list or the label on the old fan.

Noisy or weak airflow from an LG split system indoor unit

The cross flow fan spins along the full width of the indoor unit, so any damage or imbalance is easy to hear. Common reasons to replace it include cracked or broken blades, a fan that wobbles or rubs, a rhythmic thumping or squeal, or airflow that has dropped off even with clean filters. Heavy dust and mould build-up on the blades can also unbalance the fan and cut airflow. If the fan doesn't turn at all, check the fan motor and the coupling before assuming the wheel is at fault.

Fitting the cross flow fan

Turn the air conditioner off and isolate it at the circuit breaker or isolating switch before opening the unit. Fixed-wired units should be worked on by a licensed electrician or qualified air conditioning technician. Note how the fan locates on the motor shaft and the end bearing, refit it centrally so it doesn't rub, then run the unit and listen for noise.

Questions about this part

Can I clean the old fan instead?

If the blades are whole and the fan only has dust or mould on it, a thorough clean can bring back airflow and quieten it. Cracked blades, a damaged hub or a fan that still wobbles after cleaning mean it's time to fit ADP73673403.
