Sounds like a bad thermostat,you can check it with a meter by putting the meter on omes,thermostat in closed position no reading turn thermostat all the way on you should get a reading if not replace,let me know-mike

Defrost cycle is very often. Check freezer timer/thermostat might be cuts off frequently. Check thermostat setting..Check fridge is working continuously until frosting over freezer by keeping thermostat at 9' clock position. If not replace thermostat.
Good day, That's too long a period, for a normal. defrost system failure. You'll have to wait until it quits, then remove the rear panel and look for ice (not frost) building up somewhere in the freezer compartment. I have solved similar problems on this model, by replacing the defrost thermostat with a GE 60 degree thermostat, and a WR9X330 GE 6 hour defrost timer to get this model to defrost completely.
It's also possible that the refrigerant charge is slightly low, causing the defrost thermostat not to reach a cold enough temperature to perform a good defrost cycle. (building ice over a long period of time).
Make sure Freon 12 was used when replacing the compressor. Some substitutes caused the evaporator coil to act as if it was slightly low on charge.
The fridge should be between 2 and 5 degrees C or 36 and 41 degrees F and the freezer should be between -18 and -25C and 0 and -13 defgrees F. If you cant get the temp right then call a service engineer asazp.
Your refrigerator has a Control-defrost,adaptive timer ,PC board part number 241508001 This is providing your model is the one listed above your post WRS3R3EW. The model you listed in post does not come up. Until we can determine that the freezer is not defrosting you need to unplug and remove the back panel of freezer compartment to see if the evaporator coils are frozen or clear. If frozen this alone will cause a chain reaction that keeps vents to fresh food compartment open and cause freezing in that area. Go to link below and enter model number WRS3R3EW0 Then you will see a list of diagrams on left side, chose #11 this will show the control parts.

Look on your sub zero for more model numbers. I have found some information indicating that the refrigerator thermostat may be the problem but need those numbers to confirm. Thanks, Sea Breeze

This is a bad design flaw, the fridhe is cooled by fan forced air from the freazer. Two ducts vent into and out of the fridge fron the freezer and ice can block them up (which you can find if you take off all the plastic at the top and back of the fridge). Hence, when they block up, the frindge does not cool, hence the thermostat tells the fridge to keep running which makes the freezer colder and colder, making the blockage worse.
You need to not only fully defrost the freezer (which can be done quicker by removing the plastic panel in the back of the freezer and using a hairdryer) BUT also fully dry the fridge before turning it back on. To stop it happening again, avoid puting unvovered liquids or hot items in the fridge. Also avoid leaving the fridge and freezer doors open for long especially in humid conditions. As I said, it's a bad design.
