Question about Carrier Heating & Cooling
I wouldn't bypass any safeties when its part of the exhaust system of the furnace. That is the first safety that acts in the furnaces sequence of operation. The induced draft will initiate and that pressure switch will close, proving the IDM is working and flue is clear. It's primary purpose is to exhaust any fuel that may linger inside the heat exchanger and then to reject the post combustion process. Carbon monoxide becomes an issue. As far as the Infinity, these units will not start if safeties are bypassed. The unit checks all safeties/circuits for continuity, and if a switch is closed when its not supposed to be, it won't allow.
