LG French Door Mullion Shim

thingiverse

If you have an LG or Samsung refrigerator with French doors that no longer open/close properly, take a closer look at what's happening underneath. We own an LG refrigerator with a French door design and noticed something interesting. There is a slat situated in the middle of the doors for added insulation when they are closed. This slat is called a mullion, and it plays a crucial role in how the doors operate. The mullion is attached to the left-hand door, so if you open the right-hand door first, the mullion remains out of the way. However, as soon as you open the left-hand door, a curved protrusion at the top of the mullion comes into play. This protrusion fits perfectly into a curved channel located on the top of the refrigerator. As you open the left-hand door, the protrusion glides smoothly through this channel, guiding the slat to close neatly and allowing the door to open cleanly. On our refrigerator, one of the hinges for this mullion has broken off, causing it to sag slightly. Although it's not severe enough to warrant replacing the entire mullion, when we open the left-hand door, the protrusion no longer makes contact with the channel, leaving the slat in its original position. This results in a slight issue: if both doors are open and we close the right-hand door first, the slat will not be sitting closed and may get stuck, causing the left-hand door to bang into it. Describing this phenomenon has proven challenging, but fortunately, images can convey the concept more effectively. This design was created using Tinkercad software, specifically for insertion into the top of the mullion.
