Not cleaning properly and loud noise

Followed the video and changed it out in 20 minutes which did not fix the problem entirely, but I went back to the list of symptoms and watched a video on exchanging the Chopper assembly. I disassembled the interior and found broken glass and wire and string restricting the rotational functions. No replacment was necssary here, but a good cleaning was in order. This made it run like new and the glasses came out shiny again. These step by step videos have even made me think about becoming an appliance repairman. LOL! This is about the 8th time I have had success with Part Select. I have had no failures. Thank you for giving away all the secrets. YOU DEFINITELY HAVE SAVED ME AND MY FAMILY TONS OF MONEY!
