ABSTRACT:
An ambient temperature compensation arrangement for clothes dryer cycle timers in which the timer dial reference for a particular operational cycle is shifted in correspondence with changes in ambient temperature. This compensates for changes in dryer run time required for proper drying with changes in ambient temperatures by causing a given timer dial to be set so as to be advanced or to retard the selected dryer cycle time. Specific arrangements disclosed include a movable reference pointer mounted on a spirally-wound bimetal, a thermometer related dial scale and a liquid crystal band marking on the timer dial scale.
