Sub zero refrigerators are by far top of the line products. Just take a look at their price tag.. Sub zero is dang proud of their Sub zero and wolf line of kitchen appliances.
Sub zero has recently came out with an enhanced air flow kit. This kit helps noise complaints and cooling issues with the new Bi model refrigerators. They have recently realized that the way the air moves inside is insufficient. They are chaining the way the air flows inside the refrigerator cabinet. This will help keep the products inside the refrigerator cooler which in turn will help the food last longer. This kit will also make the unit run a bit more quite.
Not all models need the new enhanced air flow kit. You would need to get the model and serial number from the left side trim piece and call to determine if your model needs the kit.
