How to Fix O FF Error

This indicates ‘Cooling Off’ or Demo Mode is active; the compressor is disabled.
Locate the two top-left buttons or the specific pair for your model (commonly ‘Power Freeze’ + ‘Freezer’ or ‘Energy Saver’ + ‘Lighting’).
Press and hold both buttons simultaneously for 3-5 seconds until the chime sounds and the display restores temperature readings.

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
