What OF-OF means on a LG refrigerator

The OF-OF error code on an LG refrigerator indicates that the unit is in Cooling Off mode, also referred to as Demo mode or Display mode. In this state, the compressor is completely disabled and the refrigerator will not cool, though the interior lights and display panel continue to function normally. This mode is designed for showroom or retail environments where the unit needs to be powered on and visually operational without actually running the cooling system. The display blinks OF-OF on the temperature setting panel to alert the user that cooling is inactive.

This condition is not a component failure or system fault. No sensors, compressors, or control boards have malfunctioned. The unit has simply been placed into a programmed operational mode, either intentionally or by an accidental key combination press. Because the compressor is not running, food stored inside will not be kept at safe temperatures, making it important to exit this mode as quickly as possible.

To cancel Cooling Off mode, press and hold the Energy Saver key and the Power Freeze key simultaneously for 3 seconds. The display should return to normal temperature readings and the compressor will resume operation. If the mode reactivates on its own or the key combination does not cancel it, the control panel or main board may warrant further inspection, though this is uncommon.

Common causes of OF-OF

  1. 01

    Accidental activation of Cooling Off mode

    Wiring / connection

    The most frequent cause is an unintentional press of the Energy Saver and Power Freeze keys simultaneously for 3 seconds, which toggles the unit into Demo mode. This can happen during cleaning, moving the refrigerator, or pressing buttons on the panel inadvertently.

  2. 02

    Intentional Demo mode activation during setup

    Wiring / connection

    If the refrigerator was recently installed or purchased as a floor model, it may have been placed into Cooling Off mode at the retail location and never taken out of it before delivery.

  3. 03

    Child lock or panel interaction

    Wiring / connection

    In households where children interact with the control panel, the key combination required to trigger Cooling Off mode may have been pressed without the owner's awareness.

  4. 04

    Control panel button malfunction

    Part replacement

    A stuck or intermittently shorting button on the display panel could theoretically trigger the key combination repeatedly, causing the unit to re-enter Cooling Off mode after being cancelled. Inspect the panel for any keys that feel sticky or unresponsive.

Frequently asked questions about OF-OF

What does OF-OF mean on a LG refrigerator?
OF-OF means your LG refrigerator is in Cooling Off mode, which disables the compressor and stops all cooling. The display and interior lights continue to work, but the unit will not maintain cold temperatures. This mode is typically intended for retail display purposes and is not a sign of a component failure.
How do I fix the OF-OF code on my LG refrigerator?
To cancel Cooling Off mode, press and hold the Energy Saver key and the Power Freeze key at the same time for 3 seconds. The display should stop blinking OF-OF and return to showing the set temperatures. After cancelling, allow the refrigerator 30 to 60 minutes to reach its target cooling temperatures before evaluating whether it is working normally.
Will resetting the refrigerator clear the OF-OF code?
A standard power reset by unplugging the unit may not permanently cancel Cooling Off mode, as the setting can persist through a power cycle on some LG models. The correct method is to use the specific key combination: hold Energy Saver and Power Freeze together for 3 seconds. This is the proper way to exit the mode and restore normal compressor operation.
Is the OF-OF code dangerous for my food?
Yes, leaving the refrigerator in Cooling Off mode poses a food safety risk. Because the compressor is not running, the interior will gradually warm to room temperature. Perishable foods should not remain in a non-cooling refrigerator for more than 2 hours. Cancel the mode immediately and check food temperatures before consuming anything that was stored inside.
How much does it cost to repair the OF-OF error on an LG refrigerator?
In most cases, there is no repair cost at all, since OF-OF is a mode setting rather than a component failure. Cancelling it requires only a button press combination. If the issue is caused by a faulty control panel that keeps re-triggering the mode, control panel replacement costs can range from roughly 100 to 300 dollars depending on the model, plus any applicable labor charges.
