The French Door Mullion is an OEM part for LG refrigerators. It is a flap located between the two doors of a French door refrigerator, helping to seal the gap and maintain the internal temperature by preventing warm air from entering when the doors are closed. This component is crucial for energy efficiency and proper functioning of the refrigerator.
Over time, the mullion can wear out or become damaged due to frequent use, impact from door closures, or issues with the hinge mechanism. Causes of a bad French door mullion include wear and tear, physical damage, or a faulty hinge that causes misalignment.
Symptoms of a bad French door mullion include:
- The mullion not folding or unfolding correctly
- Visible cracks or damage to the mullion
- Warm air entering the refrigerator, affecting cooling
- Increased energy consumption
This OEM LG part is also compatible with Sears/Kenmore models.
