I looked at switch 30 last night - its the one that shows up as a problem in the switch test. It looks good from a physical point of view, I didn't reflow the wires but the contacts look good, its open and not touching, closing when i push on it.
I am wondering if the tiny diode or capacitor on the switch could be bad. Does anyone know what parts they are? I can't find them in the manual at all. it just says "all switch assemblies consist of leaf springs, contacts, separators, plastic tubing and screws to hold them to the mounting surface."
