Abstract
The biasing mechanism of a refrigerator includes a spring connected to provide biasing force in the desired directions at the appropriate degrees of door opening and an arm and roller arrangement which compliments the action of the spring. Within about 30 degrees or so of its closed position the door is biased toward its closed position. From about 30 degrees to about 90 degrees of door opening the biasing mechanism slightly biases the door toward its open position. At about 90 degrees the door is stable and beyond about 90 degrees the mechanism provides an addition stable position.
