4055582037 Genuine Damper Thermostat Assembly, Air Damper Control for Electrolux Group Fridges

4055582037 is a genuine Electrolux damper thermostat assembly for fridges. In a frost free fridge, cold air is made in the freezer and fed into the fresh food section, and this part is the gate that controls how much gets through. It responds to temperature, opening and closing on its own. There's no model list on file, so confirm 4055582037 against your fridge's parts list or the old assembly.

Fresh food section too warm or too cold?

When the damper thermostat works properly the freezer stays frozen and the fridge section holds a steady chill. If it sticks closed, the freezer may seem fine while the fridge side warms up and milk spoils early. If it sticks open, too much cold air pours in and lettuce, drinks and eggs start to freeze. Ice around the damper flap, a broken flap or a worn mechanism are the usual causes. Defrost the area first to rule out ice before replacing the assembly.

Fitting the damper assembly

Switch the fridge off at the wall and clear the shelves near the damper housing. Take a photo of the housing, any control knob setting and the wiring before removing the old assembly. Make sure the new damper flap moves freely and the air ducts are clear of ice. Allow a day for temperatures to settle, then adjust the setting if needed.

Questions about this part

Could ice be causing the problem instead?

Yes, it's worth checking first. Ice in the air duct or around the damper flap can block cold air just like a stuck damper. Defrost the fridge fully and test again. If the fresh food section still runs warm or freezes, the damper assembly is the next suspect.
