4055552428 Genuine Control Box Assembly for Electrolux Group Air Conditioners, Electronic Control Box Replacement

Part 4055552428 is a genuine Electrolux control box assembly for Electrolux group air conditioners. A control box assembly brings the control electronics together in one housing, which makes replacement simpler than changing loose components. There is a second control box with the same description, 4055552899, so the number must match. We don't hold a model list, so check the label on your old box or send both unit model numbers through the parts enquiry form.

Signs of an air conditioner control box fault

The control box houses the electronics that run the system, taking signals from the remote and sensors and switching the fans, louvres and compressor. Faults usually show up as a unit that won't respond to the remote, error codes or flashing lights, a system that starts and stops without reason, or one that runs but won't heat or cool. Storm surges, moisture and insects getting inside are common causes. Because sensors and wiring can produce similar symptoms, a technician should diagnose it first.
