4055557617 Genuine Main Electronic Control Board for Electrolux Group Appliances, Main PCB Module

4055557617 is a genuine Electrolux main electronic board, the control module that runs the appliance it's fitted to. Electronic boards are model specific, so confirm the match before you order. Look for 4055557617 on the label of your existing board, or check the model and product number on the appliance's compliance label against its Electrolux parts list.

Symptoms of a faulty main control board

The main board reads the controls and sensors, then switches the motors, heaters, valves and pumps on and off in the right order. When it fails, the faults can seem random. Common signs are no power or a blank display, error codes that keep returning, programs that stop partway through, or parts running when they shouldn't. Burn marks, swollen components or a scorched smell on the board point to a failure. Rule out wiring, door switches and the power supply first, since these can mimic a dead board.

Before you fit a new board

Switch the appliance off and unplug it, or isolate it at the switchboard if it's hard-wired, in which case a licensed electrician should fit the board. Photograph every connector before unplugging anything, and handle the board by its edges. Touch an earthed metal surface before picking it up, as static can damage electronics. Reconnect everything exactly as photographed and test.
