ABSTRACT:
A defrost control device has camming means for rotational movement and gear train means operable generally in a pair of preselected speed modes for effecting the rotational movement of the camming means. Means actuated by the camming means during a part of the rotational movement thereof toward a displaced position is adapted for translating the gear train means from one of the preselected speed modes to the other of the preselected speed modes thereof. Means is selectively operable upon the occurrence of a preselected condition for releasably maintaining the translating means in the displaced position thereof to effect the operation of the gear train means in its other preselected speed mode.
A method of operating a defrost control device is also disclosed.
