If your French door refrigerator isn’t sealing properly or showing signs of frost, this vertical mullion rail could be the fix. It attaches to the left door and helps form a tight seal between both doors, while its built-in heater prevents moisture buildup. Made of sturdy white plastic, it’s a direct replacement for worn or broken parts and helps restore efficient cooling. Be sure to check your model number before ordering to ensure it’s the right fit.

Piece that makes the left side door close
Awesome! Couldn't ask for it any better. I watched the video from Partselect multiple time and was just as easy as they said it would be. It took me longer to watch the video four times than it did for me to install it. I have a habit of 10 minute projects turning into a couple hours and this took about 10 minutes. Thanks.

Condensation inside at the top of the refrigerator. Freezer compartment icing up.
Repair was very easy. I followed the instruction provided by this site for mullion rail. The door gaskets were a simple push fit. but needed the use of a hair drier to remove crimps in the rubber. Overall excellent. The refrigerator is working and cooling well.

Top plastic clip on vertical mullion is missing. Is this part available or do i need to replace the entire rail??
For model number Jfc2089hpy2
Hello Ron, thank you for your question. That part is not sold separately. The whole rail would have to be replaced. I hope this helps!

Why is the rail on my door extremely hot
For model number 596.79212013
Hi Gary,
Thank you for your question. If the mullion is hot, the heat is generated by a heat loop located in the mullion and the walls near the gaskets to prevent moisture and frost from developing. This will usually last 24 hours. If it is warmer than normal, the issue may be with the condenser and you will need to clean it. If the air flow around the condenser is blocked by dust, dirt and other debris, this will cause the both the mullion and walls near the gaskets to become warmer than normal. It is important to clean it on a regular basis. Also, if your refrigerator has an Energy Saver feature, this controls the heat and may cause the mullion to become warmer than normal. You will need to check you owner's manual for information on how to use it. We hope this helps! Good luck with the repair!

The bottom clip on the door itself is broken. Will the mullion rail come with both sides of the clip? Or can i buy the bottom clip on the door that the rail slides into separately?

Ps11738597 is the vertical mullion part. Does it come with the clips for both sides. The clip on the left door side is broken, not on the mullion side. Can you buys those clips for the door side?
