| Ok, I dug a little more into the wiring when doublechecking HUM1 goes through the transformer. HUM2 goes through a 24 volt electronic relay and then to the humidifier.
What I noticed is when I cut power to the furnace and disconnected the wires from the humidifier to inspect the water still ran through the humidifier, could that point to a bad solenoid in the humidifier, or would that stay open even if power is disconnected? |
