If a door on the Samsung RF29BB8600 will not close, Samsung's manual points at two specific causes. First the FlexZone drawer: do not store too much food in it, because that prevents the drawer closing properly and causes frost, and make sure the FlexZone drawer and the freezer drawer are in place after removing or mounting the basket, since the FlexZone may not open or close if the freezer drawer is not in place. Second leveling: the refrigerator must be level on a flat solid floor with the front leveling screws adjusted with the refrigerator empty, or doors sit and close badly. Check food blocking a door and the gasket.

- Which door or drawer will not close and how far
- Whether the refrigerator was recently moved or the drawers removed
- Whether the refrigerator rocks or sits unevenly
Try in this order
0 of 5 completedClear the door and drawers
ReversibleMake sure food does not block a door and that the FlexZone drawer is not overfilled. Too much food in the FlexZone prevents it closing properly and causes frost.
Reseat the drawers
ReversibleAfter removing or mounting the FlexZone basket, put the FlexZone drawer in place. The manual says it may not open or close if the freezer drawer is not in place, and to check the connectors if the FlexZone indicator does not work.
Level the refrigerator
ReversibleThe refrigerator must be level on a flat, solid floor. Level it with the refrigerator empty, using a flat-head screwdriver on the levelers in the front legs.
Check the clearance
ReversibleKeep at least 2.5 inches (5 cm) between the back and sides and any walls or cabinets so doors and vents work properly.
Clean the gasket
ReversibleClean the door gasket so it seals; a dirty gasket lets moisture in and causes frost.
Model-specific
What is true of this model and not of its siblings
- Tools and supplies
- A flashlight, a level, a soft brush and vacuum for dust, baking soda for odors, a dry towel for drips and a flat-head screwdriver for the front leveling screws. Samsung says the LED lamps are not user-serviceable and to unplug before cleaning.
- Door alarm and lock
- If a door is left open for more than 2 minutes an alarm sounds and the indicator blinks; press Door Alarm to switch it off or on. Holding Door Alarm for 3 seconds locks the main panel and the Lock indicator lights; the panel locks again automatically after 1 minute of inactivity when Control Lock is set.
