Samsung refrigerator has frost or ice buildup

Samsung refrigerator has frost or ice buildup: door leakage and blocked airflow should be resolved before assuming a defrost component failed. Scoped to RF29BB8600*.

Samsung's frost table for the RF29BB8600 has three rows. Frost around the vents means food is blocking the vents: make sure no food blocks the refrigerator vents. Frost on the interior walls means the door is not closed properly: make sure food does not block the door and clean the door gasket. Frozen fruits or vegetables mean they are stored in the FlexZone: do not store most kinds of fruit or vegetables there. The manual adds that too much food in the FlexZone drawer prevents it closing properly and results in frost buildup, and that condensation forms if a door is left open or high-moisture food is not wrapped airtight.

Before you touch a setting

Record this first — changing settings destroys the evidence

  • Where the frost forms: vents, walls or the FlexZone
  • Whether the doors close and the gasket is clean
  • Whether fruit or vegetables are stored in the FlexZone

Try in this order

0 of 5 completed
  1. Clear the vents

    Reversible

    Make sure no food blocks the refrigerator vents; frost around the vents is a sign of blockage.

  2. Clean the gasket and close the doors

    Reversible

    Make sure food does not block the door, and clean the door gasket so it seals.

  3. Fix the FlexZone

    Reversible

    Do not store too much food in the FlexZone drawer, since it prevents closing properly and builds frost. Do not store most fruit or vegetables there because they freeze.

  4. Wrap moist food

    Reversible

    Condensation on the interior walls comes from moisture entering when the door is left open or from high-moisture food; wrap food airtight.

  5. Check the alarm and clearance

    Reversible

    If the door is left open more than 2 minutes the alarm sounds. Keep 2.5 inches (5 cm) of clearance so the refrigerator ventilates.

Model-specific

What is true of this model and not of its siblings

FlexZone modes
Wine sets 41 F (5 C), Deli 37 F (3 C), Beverage 34 F (1 C) and Meat/Fish 30 F (-1 C); Soft Freeze, activated by holding FlexZone for 3 seconds, sets 23 F (-5 C) and returns to the previous mode when held again. Select the mode for the food you store; meat or food in Wine, Deli or Beverage mode may spoil.
Door alarm, lock and Sabbath
If a door stays open more than 2 minutes an alarm sounds and its indicator blinks; the alarm is on by default and toggles with the Door Alarm button. Holding Door Alarm for 3 seconds locks the main panel to prevent accidental changes, and Lock re-engages after one minute of inactivity. Sabbath mode is turned on or off by holding Door Alarm and AutoFill Pitcher together for 5 seconds, stays active for 85 hours, switches off the buttons, display and internal lights while cooling continues, and stays on after a power failure until you deactivate it.
