Check the fan and readjust temperature control to higher. Thanks.

Did u check condenser on the top behind the grill? If it's clean, check unit for evaporator freon leaking. Light....Possibly bad bulbs behind that plastic light cover or light switch - one of them located on upper portion of door frame.

Error code 50 means excessive refrierator section compressor run. Possible causes include: dirty condenser, stopped condenser motor, faulty termistor or an evaporator refrigerant leak. If it is a refrigerant leak it usually shows up as frost or water driplets half way down on the back wall. Clear codes by holding the alarm button in for 15 seconds.

Subzero uses two compressors so the freezer is a separate system. The first thing to do is clean the condenser. You can find instructions on how in the owners manual or at subzero.com. They even have videos. If that doesn't take care of it you could have a bad condenser fan motor a sealed system issue or a temperature sensor issue. Also I have seen if you put something tall enough to push up on the light cover on the top shelf that can stop the evaporator fan at the top of the refrigerator section.

Make sure the condenser is clean. Instructions are in your manual or subzero.com. If cleaning it doesn't work call for service

Call a subzero repairman. My subzero had a leak in the refrigerant coolant tubing. Trust me, only a trained and equipped repairman has a prayer of fixing this.

It sounds like a defective ref section evaporator. This is common, due to poor quality metal used in fabrication. If you call subzero, they will more than likely fix it as they are aware of this issue. It probably wont cost you anything if you get them involved.
