Refrigerator Display or Demo mode is a feature built into refrigerators that completely disables the cooling components in the refrigerator and freezer. The reason for this is to conserve energy while the refrigerator is in a store as a display model. The lights and the digital control panel will still be operational. If you are having issues with your LG refrigerator, you may have purchased a floor model from the store or the refrigerator was on display or demo mode from the factory. NOTE: The display panel on your LG refrigerator (whether vertical or horizontal) will show OF F or O FF. OF F is displayed on horizontal displays and O FF is shown on vertical displays.
LG refrigerator displays OFF on panel – Demo Mode
How to get your LG refrigerator out of Display or Demo mode:
1. Be sure the refrigerator is plugged in and you are seeing OF F on the display panel.
2. Open the right side door.
3. Keep left side door (where panel is located) shut.
4. Press and hold down the ICE PLUS/LOCK button and the REFRIGERATOR button at the same time.
5. Hold the buttons down for 3 to 6 seconds.
6. The panel will return to its normal setting and you will hear an audible “ding”.
7. The refrigerator dispenser will initialize.
8. The temperature numbers will appear on the display, set the desired temperature for the freezer and refrigerator.
9. Make sure the refrigerator is now cooling and the LCD panel is functioning properly.
LG refrigerator – How to reset display demo mode
Hold both ICE PLUS and REFRIGERATOR buttons for 5 seconds
In other LG refrigerator models, you may see the LED scrolling from 1 to 7. To reset this and get the fridge off of demo/display mode, you have to open the right door and press both the “REFRIGERATOR ADJUST” button and the “ICE PLUS” button for 3 to 6 seconds.
If you buy a floor model refrigerator, scratch and dent refrigerator, or a refurbished refrigerator, chances are it will be in DEMO mode. Follow the steps above and you will have your LG refrigerator back to cooling and freezing. If you have any issues with your refrigerator not cooling, here is a page that can help you to troubleshoot the issue. If you have other error codes that display on your refrigerator panel, here is the LG refrigerator error codes page.

LG fridge Model # LFC23760SB , approx. 7yrs old, is slipping into demo mode by itself. This has happened 4-5 times in last 2 months. Any advise on this occurrence would be appreciated before we come home after an extended time away to find a fridge full of bad food. We have enjoyed all three LG appliance’s since we renovated our kitchen.
Thanks

Hello Randy, I hope you are well and got your fridge/freezer going. I’m replying to it so as to get the info needed out in the public domain. Like everybody else, I followed the instructions to no avail, so then I started to play with permutations…
To cancel/activate demo mode for GLC8839SC or GMM916NSHV
1. Ensure plugged in and switched on.
2. Open RH door of fridge (may work with other doors, but who cares?)
3. Press and hold “Fridge button”
4. Press and release “Express Freeze button” 4 times
Display will “Bleep” and either show target temperatures or “OFF” depending on what you are doing.
please l have this error OF and F on an LG refrigerator model GSJ960PZBZ. l tried the above procedure that is pressing and holding down the ice plus and refrigerator buttons for 6 seconds but it did not work. Is there anything else l can do?
one more thing the red LED on the control board does not light at all
also may l know the resistance of the Thermistors (about 4 of them 2 the freezer and 2 for the fridge side) at room temp? . How can l test the inside fan motor at the freezer compartment, it has 4 wires.
Thanks you very much

Heather,
To deactivate the Control Lock function on your LG refrigerator, press and hold the CONTROL LOCK button for 3 seconds.
DISPLAY OFF MODE: When your refrigerator is in Display Off mode, the LED display panel will remain off until a door is opened or a button is pressed.
Once on, the display will remain lit for 20 seconds.
If that does not work, unplug the fridge for 5 minutes and see if that resets the display board.
If not, you may have a bad wire harness or a bad display board that will need to be removed and replaced.

My LG 22860st Refrigerator seems to be in lock mode.
None of the control panel buttons light up or respond to touch.
Nothing happens when I hold down the lock button for three seconds, what else can I try?
