Samsung Refrigerator Error OF OF: Cooling Off Mode — Cooling System Disabled (Demo or Shop Mode)

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The refrigerator's cooling system has been disabled. This is not a fault — it is a deliberate mode used in retail showrooms to display the refrigerator without running the compressor. It is commonly called Demo Mode or Shop Mode. No cooling occurs while this mode is active.

Severity

Low - usually safe to check with basic user-accessible cleaning or inspection on the Samsung refrigerator.

Can you fix it yourself?

Yes — DIY-safe

Most likely cause

Refrigerator was set to Demo/Shop Mode by the retailer before delivery and not reset

Also displayed as OF OF, O FF, OFF OFF on some models.

Estimated time for safe first checks: 1–5 min to exit Demo Mode.

Step-by-Step DIY Fix Guide

  1. SAFETY: No electrical hazard.
  2. The refrigerator is not broken — cooling will resume immediately once Demo Mode is deactivated.
  3. For most Samsung models: press and hold the Energy Saver button and the Freezer button simultaneously for 3 seconds until you hear a chime and the display returns to normal temperature readings.
  4. If that combination does not work on your model, try pressing and holding the Fridge button and the Freezer button simultaneously for 5 seconds.
  5. Alternative: unplug the refrigerator for 60 seconds, then restore power — some models exit Demo Mode automatically on a fresh boot.
  6. Check your model's user manual (available at samsung.com/us/support) for the exact button combination.
  7. After exiting Demo Mode, allow 2–4 hours for the refrigerator to cool to its set temperatures.

If the warning comes back after restart

  • If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
  • If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
  • OF OF cannot be cleared after trying multiple button combinations and a power reset
