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.

In a refrigeration apparatus having an outer shell, an inner liner spaced inwardly from said shell, an evaporator, a defrost heater, means for mounting said evaporator and defrost heater inwardly from said liner in heat transfer relation, and a thermostat having a switch for de-energizing said defrost heater, a thermostat mounting apparatus comprising: a metal shield in heat transfer association with said evaporator, separating said evaporator and defrost heater from said liner, said shield including a top portion extending upwardly relative to said evaporator having a substantially flat surface portion and a pair of opposed raised sockets; a body of spring steel including a central portion for engaging said thermostat, said central portion defining opposite ends; first and second side portions each having a length preselected to space said central portion away from said wall less than the height of said thermostat, the spacing between said side portions being sufficient to permit inward movement of said side portions when said thermostat is disposed therebetween; first and second resiliently yieldable connecting portions connecting said opposite ends of said central portion to upper ends of said first and second side portions, respectively; and first and second tabs turned outwardly from lower ends of said first and second side portions, respectively, received in said sockets to cause said central portion to act downwardly on said thermostat and resiliently urge the thermostat in facial contact with the flat surface portion of said top portion of said shield, said tabs extending outwardly sufficiently to remain in said sockets when said thermostat causes said central portion to be under tension and thereby cause said connecting portions to resiliently urge said side portions inwardly.
