Is This the Right Part?

✅ Cross Reference Information

Common Symptoms

• Refrigerator doors do not close or seal properly at the center mullion.
• Warm air may leak through the center door seam, potentially contributing to a refrigerator compartment that is too warm.
• The mullion may remain folded outward, fail to rotate into position, or interfere with door closing.
• Condensation or moisture may appear on the mullion when the flap does not seat correctly or when ambient humidity is high.

Check Before Replacing

• With power disconnected, visually inspect the mullion for cracks, warping, loose mounting, or a broken hinge or spring.
• Open and close the left refrigerator door slowly and observe whether the mullion folds inward when open and rotates into the sealing position when the door closes.
• Check that the mullion is not folded outward before closing the doors and that it contacts the opposing door evenly.
• Inspect the center door seam for a continuous gap and check the surrounding door gasket for obvious twists, tears, or obstructions.
• Confirm that food containers or door contents are not preventing either door from closing; do not force the doors or mullion.

Pro Tip

Part Details

Key Features

• GE genuine OEM refrigerator door mullion/articulation assembly.
• Black finish.
• Spring-loaded rotating flipper-style mullion.
• Creates the center sealing surface between French-door refrigerator doors.
• Assembly may include an integrated electrical heater on applicable refrigerator designs to help limit condensation.

Installation Notes

• Disconnect refrigerator electrical power before handling or replacing the mullion assembly.
• Use the appliance-specific service or installation instructions because mounting details and electrical connections can vary by model.
• Typical replacement guidance for this style of assembly includes releasing the mounting screws, lifting the mullion from its upper and lower supports, disconnecting its wiring harness if present, then reconnecting the harness and securing the replacement in the same supports.
• After installation, verify that the mullion moves freely, folds inward with the door open, rotates into position when the door closes, and does not prevent the doors from sealing.
• Do not work on the wiring or heater circuit while the refrigerator is energized; obtain professional service if the wiring connector or door circuitry is damaged.
