Part MDS64137901 Refrigerator Center Plate Gasket
Purpose
Seals the vertical mullion to prevent cold air loss.
Details
The MDS64137901 is a genuine OEM center plate gasket (also known as a mullion seal) designed for LG and Kenmore French Door refrigerators. Unlike the large outer door gaskets, this specialized rubber seal is mounted to the vertical flipper assembly (mullion) located on the left-hand door. It creates a tight seal between the two doors when closed, which is critical for maintaining internal temperatures and preventing moisture buildup. Common symptoms of failure include visible condensation on the center rail, frost accumulation in the fresh food section, or the refrigerator running excessively due to air leaks. Replacing a torn or compressed mullion gasket restores cooling efficiency and protects food from temperature fluctuations.
Included Items
One center plate gasket; installation may require a putty knife to seat the gasket into the mullion track.
