If the freezer of the Samsung RF29BB8600 is not cold enough, Samsung's troubleshooting lists the causes: the power cord is not plugged in properly, the temperature control is not set correctly (the freezer range is 5 to -8 F), the refrigerator is near a heat source or direct sunlight, there is less than 2.5 inches (5 cm) of clearance to walls or cabinets, or the refrigerator is overloaded with food blocking the vents. Cooling Off (Shop) mode also stops the compressors: the display shows 0 for fridge and FF for freezer. Power Freeze speeds freezing for several hours and should be used at least 20 hours before loading large amounts of food.
Differential
Likely causes of “Samsung refrigerator freezer is cold but not freezing food”, and how to tell them apart
- 1
Cooling Off (Shop) mode is on
What separates it The display shows 0 and FF and the chime sounds; the compressors do not run
How to confirm Hold Fridge and FlexZone for 6 seconds, then press Door Alarm when the display blinks
- 2
The temperature is set too warm or a heat source is close
What separates it The freezer is soft and the panel shows a warm set point
How to confirm Set the freezer lower and keep the refrigerator away from sunlight or heat
- 3
Blocked vents or no clearance
What separates it Food against the vents and warm air at the back
How to confirm Do not overload; keep food off the vents and keep 2.5 inches (5 cm) of space
- 4
The power cord is loose
What separates it Nothing lights and the compressor never starts because the power cord is loose
How to confirm Plug the power cord in properly, and check the display
Before you touch a setting
Record this first — changing settings destroys the evidence
- The freezer temperature displayed and the set point
- Whether 0 and FF are shown on the displays
- Whether the refrigerator is in sunlight or tight against a wall
Try in this order
0 of 5 completedCheck Cooling Off mode
ReversibleIn Cooling Off mode the fan and lights work but the compressors do not run, so nothing gets cold. The displays show 0 and FF. To exit press and hold Fridge and FlexZone for 6 seconds, then when the display blinks press Door Alarm.
Check the temperature
ReversiblePress Freezer repeatedly to choose 5 F to -8 F. When you change it the panel shows the actual temperature until it matches, which takes time.
Use Power Freeze if needed
ReversiblePress Freezer until the Power Freeze indicator lights; it speeds freezing at maximum power for several hours, then returns to the previous setting. To freeze large amounts of food activate it at least 20 hours before loading.
Check clearance and vents
ReversibleKeep at least 2.5 inches (5 cm) between the refrigerator and walls or cabinets, and do not let food block the vents. Keep it out of direct sunlight.
Check the door and plug
ReversibleMake sure the power cord is plugged in properly and the doors close and the door alarm is not sounding.
Model-specific
What is true of this model and not of its siblings
- Panel behavior
- When you change the temperature the panel shows the actual temperature inside until it matches the set one, then the new set temperature; this takes time and you do not need to set it again. If a communication error occurs between the temperature display and the main controller, the blinking continues for an extended time and a Samsung service center should be contacted.

Stop boundary
When this stops being a self-service repair
- !If the freezer stays warm with Cooling Off exited, correct settings, clear vents and clearance, contact a Samsung service center
