Samsung Refrigerator Error Code OF OF / O FF – What It Means & How to Fix It

What Is Error Code OF OF / O FF?

If your Samsung refrigerator shows OF OF or O FF, it usually means the fridge is in Demo Mode (also called Showroom Mode).

Demo Mode is designed for stores to display the fridge without activating cooling. If your fridge accidentally enters this mode, it will stop cooling, even though it appears powered on.

Common Causes

Demo Mode activated accidentally – Button or sequence pressed by mistake
Power reset or installation glitch – Fridge may default to demo mode after being unplugged or moved
Control board miscommunication – Rare, temporary sensor error

Safe Steps to Fix

Check the display panel
- Look for “OF OF” or “O FF” on the screen
- Confirm fridge is not cooling
Exit Demo Mode
- Press and hold the Power/Alarm + Freezer buttons together for 3–5 seconds
- Or follow the instructions in your user manual for your specific model
Power cycle the fridge
- Unplug for 5 minutes → Plug back in
- Check if error disappears

⚠️ Do NOT attempt internal repairs — demo mode is a software setting, not a hardware failure.

What NOT to Do

Don’t remove panels or wires
Don’t pour water or chemicals inside
Don’t assume it’s a cooling failure without checking demo mode

Following these precautions prevents unnecessary service calls or damage.

When to Call a Technician

Contact a qualified repair technician if:

The error persists after exiting Demo Mode
Cooling is still not working after proper reset
The fridge shows other error codes simultaneously

Professionals can check the control board or other components safely.

Quick Recap

OF OF / O FF = Demo Mode / Fridge not actively cooling
Safe first steps: exit demo mode, power cycle, confirm display
Avoid DIY repairs; it’s a software setting, not a mechanical issue
Call a technician if the error persists
