140050829039 Genuine Step Valve Assembly for Electrolux Group Fridges, Refrigerant Flow Control Stepper Valve

Some Electrolux group fridges use a step valve in the refrigeration system, and 140050829039 is the genuine Electrolux step valve assembly. A step valve is a motor driven valve that controls where refrigerant flows in fridges with more than one cooling circuit or zone. Electrolux makes more than one step valve, so match this number to your parts list. Because it's a sealed system part, fitting is a job for a licensed refrigeration technician.

Signs of a faulty step valve in a fridge

Fridges with separate cooling for the fridge and freezer, or a compartment that can switch temperature, use a step valve to send refrigerant where it's needed. A small stepper motor moves the valve between positions on command from the control board. If the motor fails or the valve sticks, one compartment stays cold while another warms up, temperatures swing, or a convertible zone won't change mode. You might also hear clicking or buzzing from the rear compartment as it tries to move. The coil and wiring can be tested before anyone opens the sealed system.

Fitting a step valve

The valve is brazed into the refrigerant pipework, so replacing it means recovering the refrigerant, brazing, replacing the filter drier, evacuating and recharging. That's licensed work in Australia under refrigerant handling rules. Ask the technician to check the drive coil and control signal first, as an electrical fault may be fixed without opening the system.

Questions about this part

Can I replace this myself?

Not legally. The valve sits in the sealed refrigerant system, and in Australia only a technician holding a refrigerant handling licence can open that system. They'll also make sure the fridge is recharged with the correct gas and amount.
