Sub Zero model 680 F, inside ref area seems damp. Food also has moisture in ref section.

the air should be dry and packages not wet . I would think the defrost cycle is not working properly . may have a drain pluged or a defrost timer that is not supplying the power or the defrost terminator is cycling off at too low a tempt . . most common would be the terminator . . ck the drain and replace the terminator . there is also a drain heater that can be install if you find that to be the problem .. ..and when doing all these things clean the cond coil up on top where the fan cools the compresor . very imporant. mm

Cleaned condenser on sub sero 680f and now fridge is running high

Check to see if the condensor fan (underneath the refrigerator) and the evaporator fan (behind a panel in the freezer) are both running. If one of these is not running, the refrigerator will not have its full efficiency.

Subzero 680 - vacuum condensor message won't go away.

You can reset it by turning the unit on and off or if you have a door alarm button hold that for 30 seconds and that should clear the fault code.

Where are the coils on a sub zero 680? Vacuum condenser signal

On the top of your unit there is a grill. Open both door and look at the lip under the grill. Remove these four screws. Now, pull on the top of the grill. You will notice that it is held on by two springs. Unhook those springs and set the cover aside. The coils are on the right hand side. Use a vacuum with the soft brush attachment to clean them and avoid damaging the airflow. Also, check the fan on the other side of the coils to make sure it is running.

601R sub zero vacuum condenser notice

Your problem might be serious enough to warrant a repairman's visit. But this was my experience: An official Sub Zero repair company in NYC told me this: If the "vacumm condenser" light keeps flashing after you've opened and cleaned the condenser grill, then either pull out the plug for the Sub Zero refrigerator or turn off the circuit breaker (or fuse) in your house that leads to it, wait for some minutes and then turn back on. It is NOT enough to turn off the unit using its own internal on-off switch - it has to be totally disconnected from the AC. I did so, waited 15 minutes, turned back on, and it worked!! I had vacuumed the condenser grill twice but the "vacuum condenser" light kept flashing AND the refrig would go bonkers if set below 38. Now the flashing warning is off and it's down to 35. Great !!!

Sub zero vacuum condenser

Top of grill is held by a spring. Pull out the top and lift the grill to remove. It can then be dropped down out of your way.
