Right hand side wall in the freezer - take a look- any frozen water or moisture? Need check a drain line, usually defrost heater inside the freezer wall getting bad and draining water just freezing inside of it.

If you have water build-up on the floor of the food compartment, or ice buildup on the floor of the freezer compartment, you are probably suffering from either a frost problem or from a clogged defrost drain.
Remove everything from your freezer, including all food and any shelves. Do not remove the icemaker (if installed.)
Look at and feel the panel covering the bottom or back of the freezer compartment. Is it thick with frost?
On top freezer models, are the holes in the top of the food compartment that lead to the evaporator choked with ice?
Is there ice forming on, or lots of water on the ceiling of the food compartment?
If the answer is yes to any of these questions, there's probably a defrost problem.
If you suspect a defrost problem, first remove any icemaker that may be installed. You will see a removable panel covering the entire back or bottom of your freezer compartment. There may be 6 to 10 or more screws holding it on. In some units there is a light socket attached to the panel; you'll see this arrangement most often in side-by-sides.
If you start to get an unusual buildup of ice in one particular spot in your freezer, especially beneath the icemaker, check for water leaks.
Water leaking onto the kitchen floor not traceable to one of the problems in Chapters 4 or 6 may be from a leak in the icemaker or door dispenser water system. Icemakers have a water solenoid valve mounted on the back of the fridge, usually behind the back bottom panel, and a water tube that leads straight up the back of the fridge to the icemaker. Door dispensers have a similar water solenoid valve with a water tube that leads beneath the fridge and into the door through a hollow hinge. If your fridge has both features, it's usually a dual water solenoid valve. It can be simple or not-so-simple to fix, but basically it's just a plumbing job.
For now I want you to look at the rear wall of the freezer and see if a layer of frost is building up. Also be aware of any temperature changes taking place on either side of your refrigerator that may indicate a defrost failure. The frost buildup around the vent may be temporary and caused by a door that was not shut properly. I would ask that you check your door seals carefully to insure the doors seal when closed. Small leaks around the door seals will draw warm moist air from inside the home and cause frost buildup like what you are seeing and also cause your refrigerator to run all the time. For now try removing the frost buildup with a hair drier. I will be here if you have questions, Thanks Sea Breeze
the evaporator coil inside the freezer compartment is iced over and can't transfer cold air in thes condition,remove panel inside freezer on back side of freezer compartment and thaw it out with a hair dryer,then check the defrost heating element for continuity,if its open replace it,if its good, ,check the defrost control that powers the defrost heater
I had this problem with our 2 door frost-free LG fridge (model GR-B207EC). Perhaps you also notice a regular ice buildup in the bottom of the freezer compartment?
My solution was to switch off the fridge and unplug it from the wall, unload the freezer compartment and remove the white plastic back panel inside the freezer compartment. The panel has arrows marked around the edges where the catches are that hold it in place. Carefully flex out the panel at the catches using a large flat blade screwdriver if necessary. Ice buildup can make removal of this panel more difficult.
Behind this back panel is a condenser, under which is a silver tray, which is designed to catch the drops which fall from the condensor (this is the 'frost-free' part of the fridge). I found mine solidly frozen with ice and used a low-heat setting on a heat gun to melt the ice. In the absence of a heat gun a hair dryer will work fine, but don't melt the plastic components of the fridge. (It is also unadvisable to chip away ice with a knife of other sharp implement as you can easily slip and damage yourself or the fridge).
After fully defrosting the tray (this will take some time), including the drain hole in the base of the tray (pour a small amount of warm water in the tray and make sure it drains readily), reassemble the fridge components and restock your fridge. Remember to plug it back in and switch it on.
No more water leaks.
As an alternative to this fix ... if you have the luxury of being able to transfer the contents of your fridge to another fridge and not have to use the leaky one for a while ... empty the fridge and freezer, unplug it from the wall, leave the doors open for a week in a warm location. I didn't use this method but I reckon a week would be long enough to defrost the ice buildup behind the back panel of the freezer and allow the water to drain, yielding the same result.
you can take a ook into the freezer sect its possible that the line has frozen, nad no longer is defrost water going into the drain but rather falling on to the floor of freezer and evnetually out the door
The solution posted previously is TOTALLY WRONG. A Sub Zero ref doesn't have a heating element in the fresh food section. Only in the Frozen food section. It has 2 totally separate systems for each section. 2 Compressors and 2 evaporators. They share a condenser. If you are having ice build up in the refrigerator then the problem you are having is a refrigerant leak in the fresh food evaporator. You need to have a certified tech come out and replace the evaporator in your refrigerator section of your Sub Zero. Not sure what you are asking about the thermostat.
If the frozen side is colder than normal and some extra frost is forming where the fan blows,and there is ice in the bottom of freezer compartment, and the cool side is not cool enough, their is a good possability the defrosting unit is not removing all the frost and ice . the defrosting unit has a timer (usually near thermostat) that turns off the cooling fan and compressor and turns on a small heater around the evaporator ( about 20 minutes every 2 days) (evaporaror is cold heat exchanger coil inside the back wall behind a cover near the recirculating fan0, the fan circulates air to both compartments through two small openings, if these openeing are closed by ice buildup cool air can not circulate to the cool side. cure 1. remove all food and leave fridge off for 24 hours with doors open (take precautions to ensure children can't get locked in side and suffocate, if you get a qt of water in bottom of unit (may leak on floor) ice buildup that the defrost heater can not remove melted and was your problem . turn frig on replace food on unit. cure 2. turn frig off, remove food from both sides, remove shelves that block access to evaporator, remove cover over evaporator if you see the evaporator coils free of ice look at openings (2) to other side, one may be blocked with ice the other with frost, carefully melt ice with hair dryer.
If the evaporator coil is solid ice heater or timer or fan has failed. good luck
