Samsung Refrigerator OF OF error code

Your fridge is in Cooling Off (demo) mode - the mode stores use on the showroom floor. The lights and display work, but the compressor, fans, and ice maker are all switched off, so nothing cools.

Also shown as: OF OF, O FF, OFF

Last updated: October 6, 2026

Quick answer: Samsung refrigerator error code OF OF: cooling Off (demo) mode is on. The most common cause is demo mode activated accidentally via the control panel. Try this first — hold the two demo-mode buttons until you hear a chime. If that does not clear it, try the three-button combination.

What causes the OF OF error?

  • Demo mode activated accidentally via the control panel
  • Button combination pressed during cleaning
  • Fridge was in showroom mode from the store and never switched off
  • Control panel glitch enabling the mode

How to fix Samsung OF OF — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Hold the two demo-mode buttons until you hear a chime
    Touch and hold the two buttons used for Cooling Off mode at the same time (on many models these are the top two buttons on the left of the panel) until you hear a chime. OF OF should disappear within seconds and cooling will restart.
  2. Try the three-button combination
    If the two-button hold does not work, touch and hold the first, second, and fourth buttons together until you hear a chime. Samsung documents this fallback for models where the two-button combo fails.
  3. Use the Family Hub screen (smart models)
    On Family Hub fridges you can switch Cooling Off mode off from the Fridge Manager app on the touchscreen - it shows OFF in every compartment while the mode is active.
  4. Check your user manual for the exact buttons
    The button labels differ by model, though the button positions are the same. Your manual names the exact combination for your fridge - use it rather than guessing.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • Cooling Off mode will not turn off after trying the button combinations
  • The control panel does not respond to button presses
  • OF OF returns on its own with nobody touching the panel
  • The fridge still does not cool after the display clears

Frequently asked questions

Is OF OF an error code?

No. It is a deliberate mode, not a fault - which is why Samsung says service is not required for it. Your fridge is doing exactly what demo mode tells it to do: look alive without cooling.

My food spoiled - was OF OF the cause?

If the display showed OF OF, yes. In Cooling Off mode nothing cools, and Samsung warns the mode is not for storing food. Discard anything perishable that sat warm.

OF OF keeps coming back by itself. Why?

Usually someone is brushing the button combination while wiping the panel. If it returns with no one touching it, the control panel may be faulty - call a technician.
