Abstract
Frostless type refrigerator/freezers having a plastic liner utilize a metal heat shield disposed between an evaporator and the liner. A defrost heater located below the evaporator is controllably energized to melt frost away from the evaporator. A metal clip of spring steel removably mounts a thermostat to the heat shield above the evaporator to sense the temperature above the evaporator to de-energize the heater when the frost is melted from the evaporator.
