4055966529 Genuine Power Board for Electrolux Group Appliances, Replacement Power Supply and Relay PCB

A dead appliance with no lights on the controls can point to the power board, and 4055966529 is a genuine Electrolux one. Electrolux lists it simply as a power board, without naming the appliance, so the part number is your best guide to fit. Check the sticker on the board you're replacing for 4055966529, or send us the model and product number from the appliance's rating label and we'll confirm whether it suits.

What an appliance power board does and how it fails

A power board takes the incoming mains supply and turns it into the lower voltages the controls need, and it usually carries the relays that switch motors, lights or heaters on command. Because it handles mains power, it's often the first board to suffer after a surge or storm. Signs of a failed power board include an appliance that's completely dead, controls that light up but don't switch anything on, relays clicking without result, or visible scorch marks and swollen components on the board.
