Can I replace it myself, or is does it take some kind of calibration?

Also, the sidebar recommends posting to HVACAdvice, but as far as my search bar can find, it does not exist.

THANKS!!!

    One other thing, it looks like this is a 24v system, so not really any risk of shock. If you have a multimeter, check that the controller is sending 24v when you would expect this damper to be actuating. You should see 24v between terminal 1 and either terminal 2 or 3 depending on which way it is turning.
