An icemaker is mounted remotely from a freezer compartment. The icemaker includes an ice mold. A thermoelectric device is provided and includes a warm side and an opposite cold side. A flow pathway is connected in communication between the cold side of the thermoelectric device and the icemaker. In one aspect, a fan is operatively positioned to move air from the fresh food compartment across the warm side of the thermoelectric device and a pump moves fluid from the cold side of the thermoelectric device to the icemaker. Cold air, such as from a refrigerator compartment, may be used to dissipate heat from the warm side of the thermoelectric device for providing cold fluid to and for cooling the ice mold of the icemaker.

Provided is a refrigerator including a cabinet having a refrigerating compartment and a freezing compartment defined therein and an ice maker disposed in the freezing compartment. The ice maker includes a cold-air hole for receiving cold air, an upper tray made of an elastic material, wherein the upper tray is positioned to be exposed to the cold-air flowing from the cold-air hole, a lower tray made of an elastic material, wherein the lower tray is coupled to the upper tray to define a plurality of spherical ice chambers therebetween, a driver for pivoting the lower tray to open the spherical ice chambers, at least one thermally-insulating portion formed at a top face of the upper tray and corresponding to at least one of the ice chambers respectively, wherein the at least one thermally-insulating portion is constructed to prevent the cold-air from invading the at least one corresponding ice chamber.

A refrigerator includes a cabinet forming a storage space, a door configured to open or close the storage space, and an ice maker provided in the storage space or the door. The ice maker includes an upper tray including an upper chamber forming an upper portion of an ice chamber, a lower tray including a lower chamber forming a lower portion of the ice chamber, and an upper heater disposed along a circumference of the upper chamber so that at least two heating regions are formed at different positions in a vertical direction in the upper chamber.

A refrigerator appliance includes walls, a door, an ice container, a magnet, and a sensor. The walls define an internal storage chamber. The door has an outer panel and a door liner disposed between the outer panel and the internal storage chamber. The door liner defines a receptacle. The ice container is removably positioned within the receptacle. The magnet is secured to the ice container. The sensor is disposed between the outer panel and the door liner. The sensor is configured to align with and detect a presence of the magnet through the door liner and to detect an absence of the magnet. The presence of the magnet is indicative that the ice container is positioned within the receptacle. The absence of the magnet is indicative that the ice container is not positioned within the receptacle.
