5901A10029A Genuine Propeller Fan Assembly for LG Air Conditioners, Axial Condenser Fan Blade, LG Air Con Fan Propeller

5901A10029A is a genuine LG propeller fan assembly, which we list for LG air conditioners. A propeller fan is the axial blade that pulls air through the condenser coil, which in a split system sits in the outdoor unit. With no model list on file, compare the number on your old blade and check its diameter, blade count and hub fitting before you order.

Noisy outdoor unit or poor cooling? Inspect the fan blade

The propeller fan moves outside air across the condenser coil so the refrigerant can shed heat in cooling mode, or pick it up in heating mode on reverse cycle units. A cracked, chipped or unbalanced blade causes vibration, rattling or a rhythmic thump, and a blade that has slipped on its shaft may spin slowly or not at all. Without enough airflow, pressures rise, cooling suffers and the unit may cut out on a high pressure or overheating fault. If the blade turns freely by hand but not under power, the fan motor may be the problem instead.

Part details

• Genuine LG part 5901A10029A
• Propeller (axial) fan assembly
• Moves air across the condenser coil
• Check diameter and hub against the old blade

Changing the propeller fan

Turn the air conditioner off and isolate it at the outdoor isolator switch and the switchboard. Air con units are hard-wired, so electrical work should be done by a licensed electrician or air conditioning technician. Remove the fan grille, undo the hub nut and slide the old blade off the shaft. Fit the new one, tighten the nut securely, then spin it by hand to check clearance before restoring power.

Questions about this part

My fan blade is cracked but still spins. Should I replace it?

Yes. A cracked blade can break apart at speed and damage the coil, motor or casing. It also throws the fan out of balance, which wears the motor bearings faster. Replacing it early avoids a bigger repair bill.
