      I saw the photos a minute ago. We have certainly seen worse looking things than yours appears. The limit thermostat does seem a curious thing to defeat.

        I saw the photos a minute ago.

        We have certainly seen worse looking things than yours appears. The
        limit thermostat does seem a curious thing to defeat. There are
        instructions and wiring diagrams in the files section that will show
        how things should be.

        Good luck, Bob

            Hi Bob,

            Yes, the insides are much cleaner than I expected them to be, given that it was bought with the caveat that "it needed work". The question I'm trying to figure out is (before I plug it in), what kind of problem was it having?

            I've uploaded a couple of more pictures. The pressure switch contacts need to be cleaned up. I think while I'm at it, I'll bridge the unused contacts to improve the switch.

            I couldn't find the wiring diagram in the files section, but it's on the inside of the unit anyway, so I'll take a look at it and see if I can make some sense of it all.

            Thanks,

            TC

            Look an ES-1A Operating and Service Manual (levers) . It may not be exactly what you have but an interesting comparison to your diagram. Bob ... [Non-text

                  After checking it with a meter, it seems that the rivets that hold the blade connection points in place on the tstat have failed, resulting in intermittent contact. So they just bypassed it to keep it running.

                  Does anyone know if schematics available for the controller board?

                  Thanks!
