CA 2112719

A display is provided for indicating changes between first and second operating conditions in an appliance such as a clothes dryer. A sensing circuit senses changes in operating conditions within the appliance. A heater is connected to the sensing circuit and is responsive to various signals produced by the sensing circuit to generate heat. An elongated thermally conductive substrate is mounted adjacent to the heater for receiving and conducting thermal energy produced by the heater. A layer of thermochromic material overlies the substrate and is capable of changing colors in response to changes in the temperature of the conductive substrate.
