Question about Sub-Zero 650 / O Bottom Freezer Refrigerator
Get into diagnostic mode by pressing and holding either colder key, then pressing on/off. You can use the colder key to scroll through 5 reading labeled fe, re, f, and r look at the re temp. is it higher than 38? if it is you probably have a freon leak in the evaporater refridgerator (call sub zero...they will completely pay for this issue, even past the 5 year warranty) If the temp reads really low (like 10 on re or something) you probably have a bad fan or fan switch in the fridge portion. this unit has seperate compressors and freon for the fridge and freezer..hence the lack of problems in the freezer. hope this helps!

Looks good what are all the definitions of fe, re, f, r, and ? (you said there are five. How do we return to normal operation? I don't want to wind up in 'showroom' or 'sabbath' modes.

If your control panel displays "OF" instead of the temperature, your refrigerator is in "Cooling Off" mode. In Cooling Off mode, the refrigerator appears to be running normally, but the compressor is off so the unit does not cool. Cooling Off mode is used by retailers to save electricity when the refrigerator is on the showroom floor.
Note: Cooling Off mode is also called Demo mode or Exhibition mode.
Depending on your refrigerator, to remove your refrigerator from Cooling Off mode:
The temperature display re-appears after the unit is out of Cooling Off mode.
