4055551867 Genuine Electronic Box Assembly for Electrolux Group Air Conditioners, Aircon Control Electronics Unit

Most of the decision-making in an air conditioner happens in its electronics, and 4055551867 is a genuine Electrolux group electronic box assembly that houses them. Our records don't say whether it fits the indoor or outdoor unit, and there's no model list on file. Please confirm the number with your unit's parts list or the label on the old box, or send both unit model numbers for us to check.

Air conditioner faults that point to the electronics

An air conditioner's electronic box holds the control circuitry that switches the fans, compressor and louvres, and on reverse cycle units the reversing valve, while talking to the display and the other unit. Heat, moisture, insects and power surges are its main enemies. When it fails, the system may not power up, may ignore the remote, could trip the circuit breaker, or may show a communication or board error. Before replacing the box, a technician should rule out sensors, the wiring between the units and the fuse.

Who should fit it

Split system air conditioners are hard-wired and run at mains voltage, and outdoor units can hold a charge in their capacitors after the power is cut. Isolate the system and have a licensed electrician or air conditioning technician fit the box. Photograph every connection first, transfer the wiring exactly, and run the system in cooling and heating to check for error codes.
