Changed out a purge unit on a cvhf last week and can't get it to talk. Old purge and new purge are identical and are new one is wired same as old one. Should have been a no brainer.
Im getting conflicting stories from the local Trane store on what to do next.
Can someone tell me what I need to do to fix this?
