4055387296 Genuine Stepper Motor for Electrolux Group Split System Air Conditioners, Indoor Unit Louvre Swing Motor

This genuine Electrolux stepper motor, part 4055387296, comes from the split system air conditioner range. In an indoor unit, a small stepper motor like this moves the louvre in precise steps, setting the airflow direction and running the swing function. Order it when the louvre has stopped moving or sticks in one position. Confirm the number on the old motor first, as several similar motors are used across different units.

Air conditioner louvre not moving or swinging

Stepper motors turn in small, controlled increments, which lets the control board place the louvre exactly where it should be. When the unit starts, the louvre normally opens, and when it shuts down, it closes again. If the louvre stays shut, stops part way, jerks, clicks, or ignores the swing button on the remote, the stepper motor is a common cause. Before replacing it, check that the louvre isn't jammed by dust or a broken hinge pin, and that the motor plug is seated on the board.

• Stepper motor for a split system indoor unit

Changing the stepper motor

Turn the air conditioner off at the isolator and the circuit breaker before opening the indoor unit. The motor usually sits at one end of the louvre, held by two small screws, with a lead running to the control board. Photograph the cable route, swap the motor, then restore power and test the swing. Split systems are hard-wired, so if you aren't qualified, have a licensed electrician or air conditioning technician do it.
