ABSTRACT:
A defrost assembly for the evaporator of a refrigerator comprises a thin heating plate of thermally conductive material underlying the evaporator. An electric cord is mounted to an underside of the heating plate for heating the heating plate. A thermal insulating board underlies the heating plate. A thermally responsive cut-off terminates flow to the electric cord when the evaporator reaches a prescribed temperature. A rear portion of the heating plate forms a channel for draining-off melted water.
