Sample Model Number Tags
Model numbers can be made up of numbers (1005400, for example) or a combination of letters and numbers (LAT1000AAE). The model number will most likely appear on either a paper sticker or a metal plate. Your appliance's model number tag may look similar to the sample model number tags shown here (model number highlighted in yellow):
Verticle Mullion Rail - Apollo Gray Specifications
The vertical mullion rail with a built-in mullion heater creates a tight seal between the doors of a French-door refrigerator. This helps prevent air leaks and excess moisture buildup. If you notice condensation or an improper door seal, replacing the mullion rail can help restore efficiency. Always disconnect power before installation and ensure compatibility with your model.

Remove the existing mullion rail:
- Remove the screw from the center hinged cover. - Remove the mullion rail by pushing upward. The top and bottom hinges slide over tabs attached to the door. I had to bump it gently from underneath. - Disconnect the three wire connector that's underneath the center hinged cover.

How do I replace the vertical mullion rail ? Thanks !!
For model number JFC2089WEM
Hi Jeff, Thank you for the question. First you will need to remove the one screw in the center, When you open the doors you will see around the middle of the rail where it attaches to the door. Next slide the rail up to remove. Then remove the wire connector. Reverse the steps to install the new Rail. Hope this helps!

When i shut the left door of the fridge (this is the one with the mullion) the right door pops open. Often times we do not notice that the right door is open a the fridge keeps running. This just started happening recently. Is there a remedy of a part that can fix this problem?Thanks. Andrew
For model number GX5SHDXVY04
Good Day Andrew. Thank you for your question in regards to your unit (Model Number GX5SHDXVY04). We would recommend examining your fridge to see if any any of the shelves or bins are not properly installed or if they may have been knocked off their alignment. This could cause your door to be forced open after you closed it. Hope this helps. Best Regards.

Is it possible to just buy the center hing for the mullion instead of the entire thing.
For model number WRF560SEYM05
Hi Nathan, thank you for contacting us. No, the center hinge does not come separately. It comes attached with the flipper mullion assembly, part number PS11756813. You may need to replace the whole part. We hope that helps!
I looked at the picture for the door mullion, part number wp12722803ap. I saw part number 7 on the picture. Is this the top hinge? If so can I order just that? If I can what is the part number?
Thank you for your help
For model number Krfc300ess01
Hello George, thank you for reaching out. In the diagram, part number 7 is a screw for the mullion, not the top hinge. The hinges for the mullion are not sold separately, they come already attached to the mullion assembly. We hope this information helps!

The Rail Mulln seams to be hot. Is this normal? It has a slight odor to it.
For model number GX2FHDXVQO3
Hello Jackie, Thank you for the question. The Rail does have a built in heater but should not be too hot to touch. We suggest checking the wiring where it plugs in to make sure it is secure and there is no damage. If the issue persists, it may need to be replaced. We hope this helps!

The left side handlebar on the middle door of this Fridges screw is loose.
For model number WRX735SDBM00
Hello Margie, thank you for reaching out. According to our research, there is a set screw at the front bottom of the handle. You have to use an Allen wrench to tight that screw. If it does not help, you may need to replace the door handle, part number PS11723191. We hope this helps!
