LG Refrigerator OF F / Demo Mode: How to Turn Cooling Back On
If your LG refrigerator shows OF F on the display, it usually is not a failed cooling part. In most cases, it means the refrigerator has been put into Demo Mode or Display Mode, which turns cooling off for showroom use while keeping the lights and control panel active. This often shows up after a move, delivery, cleaning, or button presses during a power event. LG says OF F is the display for Demo Mode, and restoring normal cooling usually means turning that mode back off.
Quick Q&A
What does OF F mean on an LG refrigerator? It usually means the refrigerator is in Demo Mode or Display Mode. In that mode, the unit looks powered on, but cooling is disabled. The fix is often to open a refrigerator door and use the Refrigerator and Ice Plus buttons to deactivate Demo Mode.
What This Display Usually Means
LG’s support guidance says Demo Mode is a retail display feature that disables cooling in both sections to conserve energy while the refrigerator is being shown in a store. The panel can still light up, and the refrigerator may appear normal at first glance, which is why OF F is a common no-cooling surprise after installation or moving the appliance.
That is why this is better treated as a mode setting than a true sealed-system or compressor diagnosis until Demo Mode has been ruled out first.
What You May Notice
- OF F on the control panel
- Interior lights still work
- Buttons on the panel still respond
- Fresh food and freezer sections are not getting cold enough
- The refrigerator may sound quieter than expected because cooling is disabled
- The issue may begin right after delivery, moving, cleaning, or reconnecting power
Safety First
If the refrigerator has been warm for a while, be careful with food safety. Perishable food may need to be discarded if temperatures have stayed unsafe for too long. Before assuming a repair is needed, confirm whether Demo Mode is on and restore cooling as soon as possible.
Quick Checks You Can Try
- Open a refrigerator door. LG says Demo Mode deactivation is done with a door open.
- Look at the display for OF F. That is LG’s current Demo Mode indicator on many models.
- Try the standard LG reset sequence. Press and hold Refrigerator and Ice Plus at the same time for about five seconds.
- Listen for a beep and watch the display. LG says the panel should beep and return to temperature settings when Demo Mode is turned off.
- If your model is newer and the first method does not work, try LG’s newer sequence. On some 2019 and newer models, LG says to keep holding Refrigerator while pressing Ice Plus three times.
- Give the refrigerator time to cool back down. Once Demo Mode is off, normal temperatures do not return instantly.
Common Causes
- Demo Mode or Display Mode was accidentally turned on
- Buttons were pressed during cleaning or setup
- The unit was recently delivered or moved from a showroom-type setup
- A power interruption led someone to interact with the panel and enable the mode
- Less commonly, there may be confusion between Demo Mode and a real cooling problem if the display no longer shows OF F after settings change
Not Usually a Part Failure
When OF F is on the display, this is usually not the starting place for diagnosing the compressor, fan motors, or sealed system. The first job is simply turning Demo Mode off. If cooling still does not come back after the display returns to normal temperature settings and enough recovery time has passed, then it makes sense to look deeper.
What Beacon Usually Checks
- Whether the refrigerator is still in Demo Mode
- Whether the panel accepted the button sequence correctly
- Whether temperature settings returned after deactivation
- Whether the compressor and fans begin normal operation afterward
- Whether there is a second, real cooling issue hiding behind the mode setting
When to Call Beacon
If you have turned Demo Mode off and the display is back to normal settings, but the refrigerator still is not cooling after a reasonable recovery period, it is time for a closer look. The same goes if the buttons do not respond the way LG describes or the panel behavior does not match the usual OF F pattern.
Our friendly technicians in yellow can help determine whether this is still just a settings issue or whether a separate cooling problem is going on.
Prevent This Next Time
- Avoid random button combinations while cleaning the control panel
- After a move or delivery, verify the display shows temperature settings and not OF F
- If the refrigerator was unplugged, confirm cooling resumed after restart
- Keep the owner’s instructions handy for your exact model if the button layout differs

Frequently Asked Questions
What does OF F mean on an LG refrigerator?
It usually means Demo Mode or Display Mode is on, which shuts cooling off while keeping the display and lights active.
Will an LG refrigerator cool while OF F is showing?
Usually no. LG says Demo Mode disables cooling in both the refrigerator and freezer sections.
How do I turn OF F off on my LG refrigerator?
LG commonly says to open a refrigerator door and press and hold Refrigerator and Ice Plus for about five seconds. Some newer models use a slightly different sequence with Ice Plus pressed three times while Refrigerator is held.
Is OF F an actual refrigerator repair code?
Usually not. It is commonly a mode setting rather than a failed part, which is why Demo Mode should be ruled out first.
Why did my LG refrigerator go into Demo Mode?
It often happens after moving, delivery, cleaning the panel, or accidental button presses.
What if I turn OF F off and the refrigerator still does not cool?
If the display returns to normal temperature settings but cooling still does not recover after some time, there may be a separate cooling problem that needs diagnosis.
