A refrigerator that has a fresh food compartment, a freezer compartment, and a door that provides access to the fresh food compartment is disclosed. An icemaker is mounted remotely from the freezer compartment. The icemaker includes an ice mold. A thermoelectric device is provided and includes a warm side and an opposite cold side. A fluid pathway is connected in communication between the cold side of the thermoelectric device and the icemaker. A pump moves fluid from the cold side of the thermoelectric device to the icemaker. Cold fluid or air may be taken from the freezer compartment to dissipate heat from the warm side of the thermoelectric device for providing cold fluid to and for cooling the ice mold or cool/warm fluid to other cooling or warming applications in the refrigerator compartment or on the refrigerator compartment door.

1. A refrigerator that has a fresh food compartment, a freezer compartment, and a door that provides access to the fresh food compartment, the refrigerator comprising: an icemaker mounted on the door, the icemaker including an ice mold;a thermoelectric device disposed in the fresh food compartment,
1. A refrigerator that has a fresh food compartment, a freezer compartment, and a door that provides access to the fresh food compartment, the refrigerator comprising: an icemaker mounted on the door, the icemaker including an ice mold;a thermoelectric device disposed in the fresh food compartment, the thermoelectric device having a first side and a second side, wherein the thermoelectric device has an icemaking mode and an ice harvesting mode and when in the icemaking mode the first side is a cold side and the second side is a warm side;a first liquid refrigerant loop comprising a fluid supply pathway abutting and in thermal communication with the cold side of the thermoelectric device and the icemaker when in the icemaking mode such that heat is transferred from the icemaker to said cold side via a first liquid circulating through the first liquid refrigerant loop; andsecond liquid refrigerant loop abutting and in thermal communication with the warm side of the thermoelectric device and the freezer compartment when in the icemaking mode, such that heat is transferred from the said warm side to the freezer compartment via a second liquid circulating through the second liquid refrigerant fluid loop. 2. The refrigerator of claim 1 wherein the first liquid refrigerant loop further comprises a fluid return pathway in thermal communication between the icemaker and the cold side of the thermoelectric device when in the icemaking mode. 3. The refrigerator of claim 1 wherein the second liquid refrigerant loop further comprises a fluid supply pathway in thermal communication between the warm side of the thermoelectric device and the freezer compartment when in the icemaking mode. 4. The refrigerator of claim 1 wherein the second liquid refrigerant loop further comprises a heat exchanger within the freezer compartment and in thermal communication with the warm side of the thermoelectric device when in the ice making mode. 5. The refrigerator of claim 1 further comprising: an insulated compartment on the door;an ice storage bin in the insulted compartment positioned to receive ice harvested from the ice mold; andwherein the fluid supply pathway is in thermal communication with the insulted compartment and the cold side of the thermoelectric device when in the ice making mode. 6. The refrigerator of claim 1, wherein the first liquid is the same as the second liquid, but are fluidly isolated from each other. 7. A refrigerator that has a fresh food compartment, a freezer compartment, and a door that provides access to the fresh food compartment, the refrigerator comprising: an icemaker mounted on the door, the icemaker including an ice mold;a first fluid loop in fluid communication with the icemaker;a second fluid loop in fluid communication with the freezer compartment; anda thermoelectric device disposed in the fresh food compartment abuts and is in thermal communication with the first fluid loop and the second fluid loop such that in an icemaking mode heat is transferred from the icemaker to a first side of the thermoelectric device via the first fluid loop and from a second side of the thermoelectric device to the second fluid loop; andwherein heat is removed from the second fluid loop within the freezer compartment. 8. The refrigerator of claim 7 wherein the first fluid loop further comprises a liquid refrigerant supply pathway and a liquid refrigerant return pathway in communication between the icemaker and the first side of the thermoelectric device. 9. The refrigerator of claim 7 wherein the second fluid loop further comprises at least one flow pathway in communication between the fresh food compartment and the freezer compartment. 10. The refrigerator of claim 7 further comprising: an insulated compartment on the door;an ice storage bin in the insulated compartment positioned to receive ice harvested from the ice mold; andwherein the first fluid loop is in thermal communication with the insulated compartment and the first side of the thermoelectric device for chilling the insulated compartment when in the icemaking mode. 11. The refrigerator of claim 7 wherein the second fluid loop further comprises a liquid refrigerant supply pathway from the freezer compartment providing a thermal influence on the second side of the thermoelectric device when in the icemaking mode. 12. A method for cooling in a refrigerator that has a fresh food compartment, a freezer compartment, and a door that provides access to the fresh food compartment, the method comprising: providing an icemaker mounted on the door, the icemaker including an ice mold;positioning a thermoelectric device with an icemaking mode and an ice harvesting mode in the fresh food compartment, the thermoelectric device having a first side and a second side, wherein when in icemaking mode the first side is a cold side and the second side is a warm side;moving a first fluid from the cold side of the thermoelectric device to the icemaker via a first refrigeration loop; wherein the first refrigeration loop abuts the cold side of the thermoelectric device and the icemaker; and moving a second fluid within a second refrigeration loop to deliver heat away from the warm side of thermoelectric device to the freezer compartment. 13. The method of claim 12 further comprising the step of moving the cold fluid from cold side of the thermoelectric device to an ice storage bin via the first refrigeration loop for chilling the bin. 14. The method of claim 12, wherein the first fluid is the same as the second fluid, but are fluidly isolated from each other.
