WP12722813W - Genuine OEM Whirlpool Refrigerator Door Mullion Rail, White
WP12722813W – Genuine OEM Whirlpool Refrigerator Door Mullion Rail, White
The WP12722813W Genuine OEM Whirlpool Refrigerator Door Mullion Rail, White is an original Whirlpool replacement component designed for compatible French-door refrigerators. This white vertical mullion rail mounts between the refrigerator doors and helps create an airtight seal across the centre gap. It is suitable for select Whirlpool and other compatible brand refrigerator applications.
When the mullion rail is cracked, damaged, warped, or no longer seals correctly, it can allow warm air to enter the refrigerator and cause moisture, condensation, or cooling-performance issues. Replacing a damaged mullion with the correct OEM component can restore proper door sealing and help maintain efficient refrigerator operation.

Function & Importance of the Refrigerator Door Mullion Rail
The door mullion is the vertical rail attached to one of the French refrigerator doors. When the doors are closed, the mullion moves into position across the centre gap between the doors, helping complete the refrigerator's airtight seal.
A properly functioning mullion is important because the refrigerator door seal helps prevent warm room air from entering the fresh-food compartment. A damaged or improperly closing mullion can contribute to air leakage, condensation, frost or inconsistent cooling performance.
Using the correct OEM replacement is important because the rail must have the correct dimensions, mounting points, pivoting action, and sealing position for the refrigerator door assembly.
Common Symptoms of a Faulty or Damaged Mullion Rail
A damaged WP12722813W-type refrigerator door mullion may be indicated by:
- Refrigerator French doors not closing or sealing properly
- Visible gap between the refrigerator doors
- Mullion rail cracked, broken, warped, or damaged
- Mullion not folding or pivoting correctly
- Door does not close smoothly
- Warm air entering around the centre door seam
- Moisture or condensation around the centre of the refrigerator doors
- Frost or excessive moisture developing near the door seal
- Refrigerator becoming too warm because of air leakage
Will replacing this part fix my refrigerator problem?
If the mullion rail is damaged and preventing the French doors from sealing correctly, replacing it can restore the proper door seal and help resolve related air-leakage and condensation problems. However, similar symptoms can also be caused by damaged door gaskets, hinges, alignment problems, or other refrigerator components. Proper diagnosis is recommended before ordering.

An experienced DIYer may be able to replace the mullion by removing the existing rail from its retainers or hinge points and installing the new assembly. After installation, the mullion should pivot correctly and sit properly when the French doors are closed.
