After a closer inspection...I did notice that the drum was getting hung up on the rotation. It would turn very smoothly until it would reach the same point where there was some resistence. There was some rough plastic flashing on the inside of the drum's rotation point with the e-unit housing. I was actually able to get the full cycle function working again with an adjustment but it went back to being inconsistent. It needs the drum replaced...the one (white plastic) that was used by LTI was pretty flimsy looking. I believe the new drum will solve the problem. Thanks for all your advice and help.
