4055387650 Genuine Indoor Cross-Flow Fan Rotor for Electrolux Group Split System Air Conditioners, Tangential Fan Wheel

Split system indoor units move air with a long cross-flow rotor, also known as a tangential or barrel fan, and 4055387650 is a genuine Electrolux group replacement. Several rotors of different sizes share the same basic description, and we don't hold this one's dimensions or a model list. The safe way to buy is to match 4055387650 against the number on your old rotor or in your unit's parts list.

When a split system fan rotor needs replacing

This rotor spins at varying speeds to move air across the indoor coil and out into the room. Dust and moisture from the coil collect on the blades, and over years the plastic becomes brittle. Once a blade cracks or the rotor warps, the indoor unit starts to hum, rattle or vibrate, especially on higher fan speeds, and the airflow weakens. Black specks blowing out of the vents usually mean mould on the rotor, which a deep clean can fix if the rotor is still sound.

Tips for fitting the fan rotor

Turn off the system and isolate the power before opening the indoor unit, as these are hard-wired appliances. Have an air conditioning technician or licensed electrician do the work if you aren't trained. Note which end the motor drives and how far the hub sits along the shaft, then tighten the hub fixing securely. Spin the rotor by hand to check it clears the housing before refitting the covers.

Questions about this part

Can I just clean my old rotor instead?

If the rotor is only dirty, a proper coil and fan clean often fixes smells and black specks. A cracked, warped or out-of-balance rotor needs replacing, because the noise and vibration keep getting worse and can wear the motor.
