4055960803 Genuine Electronic Control Box Assembly for Electrolux Group Air Conditioners, Replacement Electrical Control Box

Part 4055960803 is a genuine Electrolux electronic control box, supplied as an assembly. In an air conditioner the control box houses the main electronics and their connections together in one housing. Several similar control box numbers exist, and no models are on file for this one, so the number on your old box is the key. Send the indoor and outdoor model numbers through the parts enquiry form if you need a check.

Air conditioner dead, flashing or not responding?

The electronics in the control box receive signals from the remote and the sensors, then decide when to run the compressor, fans and louvres. Faults include a unit that will not power up, an error code or flashing light on the indoor panel, no response to the remote, or a system that starts and then stops. Lightning strikes, power surges, moisture and insects are common causes of control failures. Error codes point toward the faulty area, so record any codes before calling a technician.
