What this code means

OFF or O FF usually means showroom/demo mode is active. The lights and display can work while refrigerator and freezer cooling are intentionally disabled.

Most likely causes

Demo mode was enabled accidentally through a button combination
The refrigerator was left in display mode after installation or service
A control-panel command was interpreted while cleaning or holding buttons

Safe checks for the owner

Confirm that the display reads OFF or O FF and that interior lights still work.
Use the model-specific owner’s manual to disable demo mode because the button combination varies.
After exiting demo mode, allow several hours for temperatures to fall before judging cooling performance.

Estimated U.S. repair cost

$180–$620, depending on model, access, parts availability and local labor.
