140243278052 Genuine Main PCB for Electrolux Group Appliances, Main Electronic Control Board, Match by Part Number

Part 140243278052 is a genuine Electrolux group main PCB, the printed circuit board that runs the appliance. Electrolux lists it simply as PCB Main, with no appliance or model range in the description. That makes the label on your old board the key, since boards that look identical can be loaded with different software. If your board or a technician's quote shows 140243278052, this is the replacement.

Main board faults and what to check first

The main board reads the controls and sensors and switches the motors, pumps, heaters or valves that do the work. A failed board can leave an appliance completely dead, stuck on one step, throwing error codes, or switching parts on at the wrong time. Before buying one, rule out the cheaper causes, such as a blown fuse, a loose plug, a faulty door switch or a failed component the board is trying to drive. Burn marks, swollen capacitors or water damage on the board itself point clearly to replacement.

Some Electrolux boards need configuring to the model, so check with us before ordering.
