This mullion assembly forms the front center divider of the refrigerator and includes an integrated anti-sweat heater. It helps keep the area where the door gaskets meet dry, supporting a clean look and a reliable, moisture-free seal.
- Provides the rigid center divider that the door gaskets seal against
- Built-in heater warms the divider to reduce sweating/condensation in humid conditions
- Helps limit air leaks that can lead to moisture, frost, or temperature fluctuations
- Common signs of trouble: persistent condensation on the center divider, visible cracks/warping, or poor gasket contact along the center
What's included: One mullion assembly (white) with integrated heater. Install notes:
- Disconnect power to the refrigerator before servicing; wear cut-resistant gloves
- Remove mounting fasteners, carefully release the assembly, and disconnect the wire harness (note routing/orientation)
- Position the new assembly, reconnect the harness securely, and reinstall fasteners without overtightening
- Verify doors close smoothly and gaskets contact evenly along the divider before restoring power
