I believe it would fill up to the correct level, but it's not like I left the lid open to check it. I was just happy it was working at all.

But no, the last time I tried using it, turning the dial to another setting wouldn't make anything happen, it'd just sit there.

Maybe "control module" was the wrong choice of words, I was talking about the little circuit board with an arm sticking out of it that bolts onto the motor and plugs into the wiring harness.

I had the capacitor tested at my local hardware store months ago and it checked out, but I can always take it back and have them check it again. Is it possible that it's gone bad even if it's testing at the proper microfarads?
