I am trying to determine if my pressure switch is bad. (Carrier Weathermaker 8000) On a good switch, should the continuity between the posts test open or closed?
THanks.

Open and closes on pressure increase. It is kind of like a safety tp prove the combustion blower is working. Is the small blower fan working?
