Samsung Refrigerator OF OF — Demo / Cooling Off Mode

Samsung Refrigerator · Error code OF OF

What OF OF Means

Not an error — the refrigerator is in showroom Demo Mode (also called Cooling Off). Lights and display work but the compressor never runs. Often left on after delivery or accidentally engaged.

Symptoms

  • Display shows 'OF OF' or 'O FF'
  • Fridge and freezer not getting cold
  • Lights work normally
  • No compressor sound

Common Causes

1
Demo mode enabled at the factory or store

Common after delivery — unit was on display.

2
Accidental key combo press

Children or cleaning pressed the demo activation combo.

How to Fix It

  1. Locate the demo-mode key combo for your model (often Energy Saver + Power Freeze, or Freezer + Fridge + Power Cool — hold 3-8 seconds).
  2. Watch for the 'OF OF' to clear and the display to return to temperature readout.
  3. If unsure of the combo, look in the user manual under 'Demo Mode' or 'Showroom Mode'.
  4. Allow up to 24 hours for the fridge to reach setpoint after exiting demo mode.
