On the covered Samsung refrigerator platform, OF OF, O FF means cooling Off mode, sometimes called Demo mode or Shop mode. Samsung says if the display shows OF OF, O FF, OFF OFF or scrolling temperature bars, service is not required, and that this mode disables cooling, ice making and the water dispenser. First, use your model's control sequence to exit Cooling Off, which is in the user manual.

Correct only the documented fault domain
ReversibleSamsung says the most common method, on control panels on the outside front on the left side, is to touch and hold the top two buttons on the left of the panel at the same time for 5 to 8 seconds until a chime sounds (a newer model may also need the top button on the right side, and Samsung suggests trying two buttons first). Wait a few moments to confirm the display does not return to Cooling Off, and repeat if it does.
Find the buttons
ReversibleLocate the top two buttons on the left side of the outside panel; on newer models the top button on the right side is also needed, but try two buttons first.
Hold them
ReversibleSimultaneously touch and hold the buttons for 5 to 8 seconds, until a chime sounds that differs from a single-button chime.
Confirm
ReversibleWait a few moments to confirm the display does not return to Cooling Off Mode; repeat if it does.
Feel inside both sections
ReversibleBefore you press anything, feel inside both compartments; if neither is cold while the display is lit, cooling is off and the mode is the likely cause.
