Each cam on the drum has two sets of numbers—one black and one red. You must use the color
that corresponds to a left-hand or right-hand dryer. If the eighth character of your dryer model
(see your nameplate) is "L" use only the red numbers. If it is an "R" use only the black numbers.
For example, for dryer model 6464TG1L, use the red numbers. For model 6464TG1R, use the
black numbers.
