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 with an icemaking cycle having a liquid to ice phase change. A thermoelectric device has a cold side and a warm side. A controller is in operable communication with an input to the thermoelectric device. A sensor is in operable communication with the input to the thermoelectric device and the controller. A feedback response from the input to the thermoelectric device monitors the liquid to ice phase change of the icemaking cycle.
