✅ Cross Reference Information
WR17X25027, 225D8303G002
Common Symptoms
- Visible gap at the center seam when the doors are closed
- Mullion striking the opposite door or failing to fold into position
- Doors not closing or sealing smoothly
- Condensation or frost near the center door seam
- Possible warm-air leakage at the center seal
Check Before Replacing
- Visually inspect the mullion for cracks, warping, loose mounting, or broken tabs.
- Open and close the doors slowly to confirm that the mullion folds and returns to its intended position without binding.
- Inspect both door gaskets for tears, deformation, compression loss, or gaps before attributing the problem to the mullion.
- Check whether the refrigerator is level and whether the doors appear vertically aligned.
- Check for overloaded door bins or other conditions that may pull a door out of alignment.
- Inspect the visible hinge and closure area for obvious damage or looseness without forcing the mullion.
Pro Tip
A damaged mullion is only one possible cause of a center-seam gap or condensation; also inspect the door gaskets, hinges, closure spring, door alignment, bin loading, and refrigerator leveling.
