Check the freon

Sounds like low on freon. Suggest having it checked by a professional with gauges....

Ignore the fan operation... That is perfect.

You are likely experiencing a DEFROST failure
(most commonly a defrost timer failure)...
part number 3081180 item 69 on your exploded
top view (top right side as viewed from the front).

There are typically only three (3) elements to a DEFROST
- Defrost Timer (as noted above)

- Heater element to WARM the EVAPORATOR

- DEFROST thermostat... inhibit excess heat
(closed circuit at freezing - Opens at room temperature)

Check your defrost pan...
there should be water there DAILY...

IF not: you are assured that your DEFROST fails.

You need to look for a SUDDEN REASON (huge air leak)
why FROST would form so quickly...
USUALLY a big pizza box... BUT ANYTHING blocking a
TIGHT DOOR SEAL will cause massive frosting.

It is taking moisture from the WARM ROOM AIR and blocking your evaporator...

Yes ... all INTERIOR panels must be in place for the refrigerator to function properly.

Sub-Zero units have a light and fan switch for each compartment... Check for continuity of the light switch when it is pressed and if it tests good, make sure the contacts in the bulb socket are making contact with the bulb... Be sure not to mix-up the light and fan switches as they operate opposite of each other...

Hi J.,

Side by side models have a serial tag inside the top door hinge of the freezer section
  • Open the freezer door and look up by the top hinge

When copper and aluminum are connected it cannot be welded, it has to be crimped. this is a problem that is not exclusive to sub zero, an all aluminum evaporator ( if it is in the refrigerator it's an evaporator) should resolve the problem nicely

You may have a defective door switch. The switch has a paddle that is depressed when the door is closed to turn the lights off. This switch can easily fail or sometimes, the paddle does not deploy to turn the lights on. This could be due to gunk built up on the paddle. More than likely, the switch has failed.

thats solution for your problem

Its not necessary when "Vacuum Condenser" light is blinking means That condenser is dirty. That light will come on if compressor running too long. Most common problem is that Evaporator coil in fresh food section is leaking freon. It still might keep temps ok, but compressor need to run much more to keep temperature you set. check back wall in fresh food section on left side at the middle, behind drawers. if you see moisture in one spot or a little bit of ice build up, then You will need to call people who can replace evaporator. It is pretty expensive fix. I made video how it looks to repair this problem. Thanks.

On the back of the ice bucket there is a round plastic piece that rotates. Grab it and turn it about a quarter of a turn then try to put the bucket back in. If it still doesnt go, turn it again. It should now line up and go in.
