Fellows PS-70 shredder basket ajar light is on

Here is some general advice. Shredders have an interlock to be sure they don't run while the basket is not in place. They don't want you holding the head unit and it starts running and shreds your fingers. So you need to look for the switch that tells the head unit that it is in place over the basket. I'm guessing here but it might be something like a little plastic protrusion that pushes into the head unit to activate a swith. It is possible that the little plastic piece is broken and is not activating the head unit. That would explain why the display thinks that the basket is ajar or misaligned. BE CAREFUL if you tinker with the interlock and be sure it is unplugged!! That is an ORDER!
