What does the OF F error mean on LG refrigerators?

Demo or display mode is active, so refrigerator and freezer cooling are disabled.

What should I check first for the OF F error?

Protect perishable food because cooling is disabled while display mode is active. With a refrigerator door open, hold the Refrigerator and Ice Plus buttons together for five seconds on models covered by LG's guide. Confirm the panel beeps and normal temperature settings reappear.

When should I stop troubleshooting the OF F error?

Do not rely on the button combination when the model manual specifies a different control sequence. Request support if normal temperature settings do not return or cooling does not resume.
