Genuine GE refrigerator mullion articulation assembly used in the hinged center divider between French refrigerator doors. GE's official parts page lists WR03F04420 as a genuine GE part; established parts distributors identify it as a refrigerator mullion articulation assembly.
The mullion mounts to the left fresh-food door on compatible French-door refrigerators. As the door closes, the mullion folds into position and helps the two door gaskets form a continuous seal.
A cracked, loose, misaligned or sticking mullion may contribute to a centre-door gap, condensation, warm-air leakage, frost or doors that do not close smoothly.
Is This the Right Part?

Common Symptoms
- Gap visible between the two French doors when closed
- Condensation or frost near the centre door seam
- Warm air leaking through the centre of the refrigerator
- Mullion striking or not folding against the opposite door
- Doors not closing smoothly or sealing correctly
Check Before Replacing
- Inspect the mullion for cracks, warping, or broken mounting tabs
- Check the door-closing spring and hinge alignment
- Inspect both door gaskets for tears, compression loss, or gaps
- Confirm the refrigerator cabinet is level — an unlevel unit can cause door misalignment
- Check for overloaded door bins pulling the door out of alignment
