    Here's another video.

    I'm thinking I will change part #7 in the following diagram.

    Any other suggestions?

      This check valve was the cuprit. Old one on the left has three broken black tabs. $26 part. Add the $60 I unnecessarily spent on a new switch assembly and im up to $86 to get my $300+ compressor up and running.

        Sorry we steered you wrong, but glad you uncovered the problem.
        Is the check valve located so close to the switch that you could not
        tell exactly where it was coming from?

        It's tough to troubleshoot something you can't physically see
        or touch without any first hand knowledge of the specific tool.

        It's been 5 weeks since you first posted this but I wonder how
        long it would have been if you took it to a repair center and
        how much it would have cost.

          I'll echo the "sorry". I don't recall ever seeing a check valve fail, but it makes sense. Just the discription of air leaking from in and around the pressure switch led me to believe the problem was there and in it's unloader mechanism. I am of course not familiar with this compressor and on both my Craftsman compressors and the industrial compressors that I'm familiar with, the check valve is on the tank, completely separated from the pressure switch. Guess I should know not to diagnose something I'm not seeing.
