We recently moved into a home that has the humidispray unit. It doesn't appear to be working and I downloaded the owner manual from this site, thanks! I'd like more information though so I can troubleshoot and replace defective parts. Are wiring diagrams, service manuals available.

The solenoid is labeled 24V (AC or DC?) so I found the small transformer near the furnace electrical switch. I'm not measuring any voltage at the secondary, AC or DC. Shouldn't the supply be constant here? Perhaps my primary is open or if the unit is DC there are open parts after the secondary?

The solenoid will be 24 VAC. As for the transformer you have found, it is hard to say for sure how they have it wired. You will need to check both the input and output voltage on the transformer to determine if it is bad.
