Mission complete & Mama's happy again - just stopped back to say, THANKS
I did not make clear, this was a DIY job
I did not spend the extra $80 and replace the rollers but did oil them & the tensioner - good tip
Based on all the lint build-up that was cleaned from the inside of the unit & vent, I set a clean schedule every 3 years. WOW, what a fire hazzard.
Thanks again, Boys
