Never heard of anyone rebuilding their own compressor bu I am sure someone has done this. WRT the wiring diagrams, both the 67 and 68 are available on Vicki's site. They are similar but not exact. The 68 is in the wiring diagrams, the 67 is in the Supplemental manual.
I mean has someone done it themselves or had it done for them. For starters I want to confirm the parts so I will check out Vicki's site.
