For a warm Samsung RF29BB8600, the manual's table lists four causes and fixes: the temperature control is not set correctly (fridge 34 to 44 F, freezer 5 to -8 F, and Power Cool or Power Freeze can speed cooling for several hours), the refrigerator is near a heat source or in direct sunlight, there is not at least 2.5 inches (5 cm) of clearance to walls and cabinets, or it is overloaded with food blocking the vents. Cooling Off (Shop) mode also leaves it warm: the displays show 0 and FF. The panel shows the actual temperature until it matches the set one, and that takes time.
Differential
Likely causes of “Samsung refrigerator is not cooling enough”, and how to tell them apart
- 1
The temperature is set too warm
What separates it The panel shows a warm set point for the fridge or freezer
How to confirm Set the temperature lower using the Fridge and Freezer buttons
- 2
A heat source, sunlight or too little clearance
What separates it The refrigerator is against a wall or near an oven and runs constantly
How to confirm Keep it away from direct sunlight or heat and leave at least 2.5 inches (5 cm) around it
- 3
An overloaded refrigerator blocks the vents
What separates it There are warm spots and uneven temperatures because an overloaded refrigerator blocks the vents
How to confirm Do not overload; do not let food block the vents
- 4
Cooling Off (Shop) mode is on
What separates it 0 and FF show, the chime sounded and the compressors are off
How to confirm Hold Fridge and FlexZone for 6 seconds, then press Door Alarm
Before you touch a setting
Record this first — changing settings destroys the evidence
- The actual temperatures displayed and the set points
- Whether 0 and FF show on the display
- How close the refrigerator is to walls and heat
Try in this order
0 of 5 completedSet the temperatures
ReversiblePress Fridge repeatedly to choose 34 to 44 F, or press until the Power Cool indicator lights to speed up cooling; press Freezer for 5 to -8 F or Power Freeze.
Use Power Cool
ReversiblePower Cool speeds cooling at maximum power for several hours, then the fridge returns to the previous setting. Use it to cool quickly after the door was open; turn it off manually if not needed since it raises power use.
Check the surroundings
ReversibleKeep the refrigerator away from direct sunlight or a heat source and keep 2.5 inches (5 cm) between the back and sides and any walls or cabinets.
Unblock the vents
ReversibleUnblock the vents, and do not overload the refrigerator, and do not let food block the vents.
Exit Cooling Off mode
ReversibleIf the display shows 0 and FF, hold Fridge and FlexZone for 6 seconds, then press Door Alarm when the display blinks.
Model-specific
What is true of this model and not of its siblings
- Power Cool and Power Freeze
- Power Cool runs at maximum power for several hours and then the fridge returns to the previous setting; use it for foods that spoil quickly or after a door has been open a while. Power Freeze does the same for the freezer, and for large amounts of food it should run at least 20 hours before loading. Both increase power consumption and can be turned off by pressing the button again.
