OF OF on a Samsung refrigerator means demo mode (Cooling Off) is active—cooling is completely disabled and food WILL spoil. Press and hold the top two buttons on the left side of the control panel for 8 seconds to exit. For Family Hub models, use Apps > Fridge Manager > Fridge Settings > Cooling Off > Deactivate.

The OF OF display on Samsung refrigerators indicates Cooling Off mode, also known as demo mode or shop mode. This is NOT an error code—it’s a service mode that completely disables all cooling functions. Your refrigerator will not cool, make ice, or dispense water while in this mode.
Critical Warning: Food WILL spoil if left in OF OF mode. Exit this mode immediately if you have food stored in the refrigerator.
What OF OF Mode Means
When your Samsung refrigerator displays OF OF (or O FF), the control system has:
- Disabled the compressor — No cooling occurs
- Disabled ice making — Ice maker will not produce ice
- Disabled water dispenser — Water will not dispense (on some models)
- Kept lights and display active — For retail demonstration purposes
This mode exists so retailers can display refrigerators without running the compressor. It reduces energy consumption and noise in showrooms.
Important: OF OF is NOT the Same as 88 88
Many people confuse these two displays:
| Display | Meaning | Action |
|---|---|---|
| OF OF | Demo mode—cooling disabled | Exit demo mode |
| 88 88 | Communication error | Power cycle to reset |
If you see 88 88, your refrigerator may still be cooling. See our 88 88 troubleshooting guide.
Why OF OF Activates
Common reasons your refrigerator entered demo mode:
- Left on from retail display — Installer didn’t disable after delivery
- Accidental button press — Cleaning the control panel
- Children playing with buttons — Button combination held too long
- Power surge — Rare, but can sometimes trigger mode change
How to Exit Demo Mode by Model Type
Standard Digital Display Models
Primary method (works on most models):
- Locate the top two buttons on the LEFT side of the control panel
- Press and hold both buttons simultaneously
- Hold for 8 seconds
- Wait for a chime sound
- “OF OF” disappears and temperature displays
If primary method fails—try these button combinations:
| Button Combination | Hold Time |
|---|---|
| Energy Saver + Power Freeze | 3-5 seconds |
| Energy Saver + Freezer | 10 seconds |
| Energy Saver + Lighting | 3-5 seconds |
| Power Freeze + Lighting | 8 seconds |
| Freezer + Ice + Fridge | 5 seconds (some Side-by-Side) |
| Button 1 + Button 2 + Button 4 | 8 seconds |
If one combination doesn’t work, try another. Samsung has changed button layouts across model years, so the exact combination varies. Start with the top two left buttons, then try combinations involving Energy Saver.
Family Hub Models (Touchscreen)
- Tap Apps on the touchscreen
- Open Fridge Manager
- Tap Fridge Settings
- Tap Cooling Off
- Tap Deactivate
- Tap Proceed to confirm
The screen will show cooling resuming and temperatures will begin displaying.
Bespoke Models
- Hold < (left arrow) + > (right arrow) buttons simultaneously
- Hold for 6 seconds
- Display will blink
- While blinking, press the O button to disable demo mode
Convertible Models
Hold Temp. + Power Freeze + Lock buttons simultaneously for 5 seconds until you hear a chime.
After Exiting Demo Mode
What to expect:
- Chime sounds — Confirms mode change
- Temperature displays — Numbers replace OF OF
- Compressor starts — You may hear humming within minutes
- Fans begin running — Air circulation resumes
Stabilization times:
- Control panel may take up to 4 hours to display accurate temperature
- Refrigerator may take up to 28 hours to reach target temperature
- Keep doors closed as much as possible during this period
Food Safety After Demo Mode
If your refrigerator was in OF OF mode with food inside, check temperatures:
| Food Location | Safe if… | Discard if… |
|---|---|---|
| Refrigerator | Below 40°F | Above 40°F for 2+ hours |
| Freezer | Still frozen solid | Thawed and above 40°F for 2+ hours |
When in doubt, throw it out. Use a food thermometer to check internal temperatures of perishables.
Perishables to discard if above 40°F for 2+ hours: Raw/cooked meat, poultry, fish, milk/dairy, eggs, soft cheeses, leftovers.
