Inducers are usually sold as an entire assembly which makes it easier to replace.
I replaced the inducer. I believe I put everything back the way it was (pvc pipe, screws , electrical and 2 hoses), but it starts up but never produces heat. It shuts down and gives a code of "pressure switch open, should be closed" (3 flashes). Any ideas?
