Bottom Freezer Refrigerator - Condensation on Articulating Mullion (Door Flap)

From time to time, you may see condensation, sweat, or moisture form on the Articulating Mullion (flap) on the edge of the Fresh-Food door of your Bottom-Freezer refrigerator. This usually happens during warmer times of the year and/or periods of high humidity. As warm air hits the cold surface, condensation can develop.
 

What Is the Articulating Mullion

The Articulating Mullion is the rectangular, rotating flap on one of the fresh-food doors of your French Door Bottom-mount refrigerator. It is attached to the edge of the door by a spring-loaded hinge. When the door is closed and the mullion hits the "striker" (at the top middle of the case edge), the movable "flap" immediately rotates to a position where it becomes a surface on which the other fresh-food door can seal closed against. The mullion lies flat when its door is open.
 

What to Do When You See Condensation on the Articulating Mullion

To remove this moisture on the mullion:
  • Simply wipe the surface dry.
  • Check your control panel for Humidity or Energy-Saver controls (not on all models).
    • If you have Humidity controls for the external doors, try turning the setting to ON.
    • If you have Energy-Saver controls, try turning the setting OFF.
    • Part of how all refrigerators work to cool your food is to absorb and expel the warmth from the inside of the compartments to the surface of the case. While adjusting the Humidity or Energy-Saver settings will use a little more energy, the refrigerator will use the normal warmth of the case in these particular areas and help the moisture evaporate.
  • If your refrigerator model does not have Humidity or Energy-Saver settings that you can control, then controlling the humidity and temperature in your kitchen with air-conditioning will eliminate this condition.

Support

If you determine that the articulating mullion is not working properly, then a technician will be required to diagnose and repair the refrigerator. Schedule a service appointment with Bodewell.
