The rail mullion--I believe it is part number W10153146 has come away from the door at its top attachment. It is still attached at the middle and bottom attachments. Nothing appears to be broken. Could I have some guidance in correctly reattaching it at the top?
When you look at the center there should be 1 or 2 screws that are located there. Remove these screws and lift up on the mullion. The top and bottom will slide onto a wide post that is on the door itself and slide down. Then put the screws back in place.
Why is there wiring in the mullion? Is it heated?
Answer Hello Colleen. Yes, the mullion is heated to help the gaskets seal.
Trying to find out how to install Rail-Mulln. does this effect water dispensing?, if Rail-Mulln is missing do I need any other parts, screws, caps, etc
Answer Colleen, If the mullion strip W10151713 is missing, you will want to check the left door liner and make sure the liner isn't damaged, cracked or broken If the liner is Ok, When you open the left refrigerator door, you will find "hinges" or "pivots" mounted to the door liner assembly, You will need to remove the two hex head screws holding the top pivot and the two screws holding the middle pivot. You can then raise the mullion strip up an inch and disconnect the wiring harness in the middle pivot, and change out the part. You may need the mounting screws M0238331, if they aren't there or have been discarded by mistake. The mullion strip, doesn't have anything to do with dispensing water, so you will need to check to see if the water tank is frozen, or the water valve has failed. Both parts are located behind the panel on the right side of the back wall of the refrigerator compartment.
