    Call a professional? There is an NTI rep on this site, maybe he can get you in touch with the right person.

    Don't fire the parts cannon right off the rip. That is a very expensive way to do diagnostics.

    Time to find out how far you are getting power. It probably wasn't the controller... check your hot feed, check the neutral, and check the ground -- all the way from the fuse or breaker box to the boiler.

    Listen to Jamie, start from A and go through B,C,D... then to E. It sounds like this time you skipped a couple steps. That boiler has a few internal fuses, and if I remember correctly the sentry is powered by 24volt, so test transformer and safety loop. But it has been awhile.
