Sub-Zero Refrigerators - Recent Questions, Troubleshooting & Support
Sub-zero refer.611/s is working fine but the freezer compressor has been running 24/7 for the last 2 weeks. Sometimes the freezer drops from it's setting of zero to 16-. Coils are clean and fan works.
I think it isn't fine because if a fridge/freezer that is otherwise healthy runs continuously (due to a thermostat fault), it would be colder than you could imagine with lower than arctic temperatures in the freezer compartment, minus 30-40 C for example.
The conclusion must be your fridge isn't fine.
Proper freezer temperature, incidentally, is minus 25-27 C for food to have a reasonable lifespan with minimal deterioration. There is no benefit from being colder but significantly warmer would mean the freezer contents should be replaced much more often - the freezer compartment of an old fashioned fridge (about minus 5) was reckoned to give fish, meat and dairy up to one month safe lifespan.
A fridge that runs continuously (where the thermostat is good) could have a refrigerant loss resulting in a huge drop in efficiency, the insulation could be failing, the compressor could be failing or the de-icing panel could be permanently switched on - or any combination of these things.
I note you say the coils are clean. If the refrigeration system is good with the compressor running continuously the coils will be hand-hot.

Hi,
Many times a freezer and/or refrigerator
do not work right because of a dirty condenser coil...there are also many other
things that can go wrong.
If you are hearing a clicking or buzzing then check out the
last two tips.
If your refrigerator is running but warm, then…
Check out this tip that I wrote about that... it is a great place to start
trouble shooting your unit...and something that you can do rather then calling
a repair person to do a simple thing for you...

Our Sub Zero 736TC has
The drain at the rear of the fridge is possibly clogged. To check: Remove all the shelves and crisper in fridge, remove the lighting diffuser panel you will then see 3 screws at the top of the back panel. Undo these screws and lift the panel up and out. This will expose the drain trough at the rear base of the fridge compartment. There is a small drain hole right in the middle of the trough. I found mine to be completely clogged and the trough was overflowing into the fridge compartment.Use a small wire (I used a twist tie wire) to poke into the hole and open up the drain.This should stop the problem, as any water will now drain to the tray in the base and evaporate.I also found that the door was really hard to open immediately after it was closed and after I cleared the drain this problem wnet away (I think the clogged drain was allowing a vacuuum to be created in the fridge when the door closed.
Why is my sub zero fridge model 590 warming up?
Hi fridges will warm up on the outside as they remove heat from the inside. excessive heat with not extreme cooling inside the fridge indicates a possible degridation of coolant fluid or a leak. as the motor tries to cool the fridge the thermostat inside stays on as the tempreture inside has not been reached. if you hear the motor/ pump continually running this will indicate a cooling problem.

I have a sub zero
It is possible to replace the connector but might be hard to find the exact match. Maybe consider going to Fry's or a local electronic hobby store and replace both sides of the connector. You might even be able to find one that does a better job at moisture sealing...maybe an auto parts store that has replacement connectors for the engine compartment.

How do remove the wood panels from a sub-zero 561 refrigerator
When you open the door, you will see screws holding the handle in place. It would be best to have an extra set of hands to support the handle as you remove the screws. Once all the screws are out then the handle will come off and the panel will slide out. Sometimes you will need to remove the top trim as well.

My sub zero 601r no cooling
How soon did you start it up after you moved it & put it in its place?
If you plugged it in to soon after moving. Oil may have still been up in the wrong place of the compressor. Unplug it for about an hour. Then plug it back in. By plugging it in to early after moving you could have burnt up the compressor. This happens often.

Leaking sub zero 650
I fixed my leaking problem by pulling out the vegetable drawer and checking the condensation drain hose. Sure enough, it was clogged and the condensation had nowhere to go but move out toward the front of the fridge, down the left side and onto the floor. Once that drain hose was cleared (with a bendable straw), no more leak!
