Controller
I see the controller. It's basically everything electronic for the vacuum runs through it. I thought it was small board.
I'll tell you what to do. If you know a vacuum dealer or someone who fixes them. You find a used one. If you can't it's a parts machine.
I didn't realize it was a $300 part.
You can find one I'm not sure of the cost. If you want money out of it this is it.
