sounds like a "performance problem" try pressing and holding the reset button for 3 seconds.

Most likely you have a leak in the evaporator. Subzero warranties the parts for 12 years. Call them to find out what they will cover. They are agreat company and will be fair with you.

My husband removed the covers inside the fridge which contain the lights and the cooling fan. The problem was the icing up of the cooling fan (which circulates the cold air) preventing it from rotating also the drain hole at the bottom of the fan was also iced up.
The fridge was switched off at the wall socket whilst working on it. After removing the panel containing the fan and unplugging the connection take the panel outside. A hair dryer was used to thaw out the ice. The drain hole was made slightly bigger to hopefully prevent this happening again.
When panel is screwed back in fridge make sure the black sealing tape is in position also take care not to damage cooling pipes which are attached to the evaporator unit. Defrosting a couple of times a year might prevent this happening again. It seems to be a design problem which im sure the makers will be aware of and modify future appliances. Q Will the makers repair this problem free of charge even if the warranty has expired !?

I just went through this with my refridgerator and actually posted one of the questions. Here is what I found ........

In the freezer compartment behind the panel there is an evaporator fan which pulls cold air from the freezer and pushes it up into the refrridgerator compartment. If the fan is not working it is one of three things.. 1) there is so much frost in the fan area the fan blade is stopped and cannot push the cold air into the refridgerator compartment or the air channel is blocked. 2) there is no electricity going to the fan (usually tied to the door switch of the refirdgerator compartment, and 3) the motor is dead and will have to be replaced.

Solution to #1 - defrost but there is another problem in the "frost-free" part of the system which must be addressed or the frost will return and it will happen again in the future.

Solution #2 - check to see there is power to the fan. (most are 110VAC but some are 100VDC. Use a meter and check)

Solution #3 - If there is power, the motor is dead. Replace the motor. Be aware that AC and DC motors are different and replace per manufacture's specifications.
