What OF OF Means

OF OF (sometimes "O FF" or "OFF") is not a fault — it means the fridge is in Cooling Off / Demo (showroom) mode, so the compressor will not run.

Symptoms

  • OF OF shown

Common Causes

1
Demo / Cooling Off mode enabled

Accidentally activated, or left on from the showroom.

How to Fix It

  1. Exit Cooling Off mode: on most models, press and hold Energy Saver + Fridge (or Power Freeze + Power Cool) for about 3 seconds.
  2. Check your model manual for the exact button combo.
  3. The display should stop showing OF OF and cooling resumes.
