REVERSING TIMER SPIN/DWELL

ADJUSTMENTS

Dual timer models with "reversing option" have an electric reversing timer in the electric service box which is
located in the upper rear area of the dryer.

Both the dwell (stop) time and basket (tumbler) spin time are adjustable by mode selection switches located on
the electronic timer (as noted in the illustration below).
