LG Refrigerator OF F Code — Demo / Display Mode Active
What this means
When OF F appears on the display, the refrigerator is in Demo Mode (also called Display Mode or Showroom Mode). This mode disables the compressor and all cooling functions while keeping the lights and display active. It is designed for retail showroom displays. The refrigerator and freezer will not cool while this mode is active.
Alternate codes: OFF, O FF
