How to get samsung refrigerator out of demo mode

0F 0F on a Samsung refrigerator display indicates that your unit is in DEMO Mode. In DEMO mode, the lights work, but the refrigerator/freezer, fans, etc. will not operate (this mode is for display/retail purposes in appliance stores). Unfortunately, Samsung does not include any info re: DEMO mode in their user manuals.

To exit DEMO mode and return to operating mode, you will need to push 2 display buttons simultaneously for ~ 3 seconds (you'll hear a small chime, then the display window will display the freezer/fridge temps and will then be out of the 0F 0F DEMO mode). The 2 display buttons that you have to press simultaneously will depend on the model of Samsung refrigerator that you have.

I have a Samsung RF18HFENBSR model (french door, bottom freezer, display at top center of fridge compartment). For this model, you press the Power Freeze & Freezer buttons at the same time to enter/exit DEMO mode).

You might try googling Samsung XXXXXXXXXX Demo Mode, where XXXXXXXXX is your model number, and you may find the display button combo for your model. If not, then you can probably get the combination from Samsung support to return your unit to normal operating mode. Your appliance store may also have that information.

You may have it in "Demo" mode. Watch video to correct. Samsung Refrigerator Troubleshooting Demo Mode

Your refrigerator is in demo mode.

The manual doesnt mention nothing about "demo mode", therefore try just to pull the power (turn off) wait 5 minutes and then turn it on again.
