Error code OF OF
Appliance Refrigerator
Quick answer

OF OF means Cooling Off mode, also called demo or shop mode. It is not a fault, and holding the panel buttons for 5-8 seconds turns it off.

Model compatibility: Samsung reuses codes across series and model years, so OF OF may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

OF OF is Cooling Off mode (demo or shop mode), not a fault.

If the display of a Samsung refrigerator reads OF OF, O FF, OFF OFF, or shows scrolling temperature bars, the refrigerator is in Cooling Off mode. Some call it Demo mode or Shop mode. It is not a fault, and service is not required.

Turning Cooling Off mode off

The exact steps depend on the model and are in your user manual. The most common method applies to control panels on the outside front of the refrigerator, on the left side.

  1. Find the top two buttons on the left side of the panel. Newer models also need the top button on the right side.
  2. Try only the two buttons first, since you are less likely to be in Cooling Off mode by accident on models that need three.
  3. Touch and hold them together for 5-8 seconds, until a chime sounds. It sounds different from the chime of a single button.
  4. Wait a few moments to see that the display does not return to Cooling Off mode. If it does, repeat the steps.
