Secondary cooling path in refrigerator

A refrigerator comprising:

• a refrigerator cabinet having a fresh food compartment and a freezer compartment, the freezer compartment mounted below the fresh food compartment;
• a first fresh food compartment door for providing access to the fresh food compartment;
• an ice compartment mounted at the first fresh food compartment door, the ice compartment comprising an ice maker and an ice bin;
• a secondary cooling path for circulating liquid coolant through the refrigerator wherein the liquid coolant is cooled by the freezer compartment and wherein the liquid coolant cools the ice maker and the ice bin as the liquid coolant circulates through the secondary cooling path;
• a pump positioned along the secondary cooling path for pumping the liquid coolant through the secondary cooling path;
• and
• wherein the secondary cooling path being configured to provide for cooling the ice maker to a lower temperature than the ice bin to thereby attract moisture to the ice maker.

• a pump positioned along the secondary cooling path for pumping the liquid coolant through the secondary cooling path;
• and
• a primary cooling path for circulating cold air wherein the primary cooling path circulates cold air from the freezer compartment to the ice maker compartment and from the ice maker compartment to the fresh food compartment to thereby reduce frost buildup inside the ice maker compartment.

• and
• a valve in fluid connection with the pump wherein the valve provides for switching between circulating liquid coolant through the secondary cooling path and circulating a hot liquid through the secondary cooling path.
