4055960381 Genuine Electronic Box Assembly for Electrolux Group Split System Air Conditioners, Air Con Control Electronics Box

Electrolux part 4055960381 is a genuine electronic box assembly for split system air conditioners in the Electrolux group range. In split system parts lists, the electronic box is the housing that carries the control electronics and their wiring, and this one is supplied as an assembly. Electrolux doesn't say whether it belongs in the indoor or outdoor unit, and no model list is on file, so match 4055960381 against the label on the box you're replacing.

What the electronic box does in a split system

Every split system relies on its control electronics to read the room and pipe sensors, respond to the remote and switch the fan motors and compressor at the right moments. The electronic box keeps those parts together in one protected housing with their wiring and connections. When something in it fails, the unit may not power up at all, may ignore the remote, may flash an error on the indoor display or may start and then shut down after a few minutes. Power surges, storms, moisture and insects getting inside are common causes of damage.

Before you fit the electronic box

Isolate the air conditioner at the circuit breaker and wait a few minutes for stored charge to drain before opening anything. Photograph every plug and terminal so the wiring goes back exactly as it was. Because the box connects to the unit's fixed mains wiring, it should be fitted by a licensed electrician or air conditioning technician. Test the system from the remote before the covers go back on.
