My ten year old furnace has an Aprilaire humidifier (Model 550) on it. It
has quit working. I clean my furnace filters monthly and oil the motor as
required, but I completely forgot to clean the in-line strainer that is on
the humidifier. I tool it apart and cleaned it but the humidifier still
does not pump water through the system I'm guessing that the humidifier
"pump" was water cooled and has burnt out. Before I go buy an replacement
part, could it be something else? Thanks!

I would get a new drip type humifier they are much better and you will not
have anywhere near the maintenance as all you need to do is change the filter.
there is a solenoid to turn the drip of water on and off. No standing water
so no scum or mold isssues are a major plus

Wayne,

What you are describing sounds EXACTLY like the OP's Aprilaire 550.

It is possible that the solenoid is shot. Listen for it when the
furnace kicks on or "hotwire" it to 24v and listen for it to come on.
Do you get water out of the line if you disconnect it and open the
valve?

JK: Yes, this is a drip humidifier. I hear the "click" when I adjust the
humidifier setting in the hallway, and yes, I get water out of the line when
I disconnect the feed line going into the solenoid. I do not here a "click"
at the solenoid.

Fortunately, these are relatively simple in design. Sounds like the
solenoid, and it shouldn't be pricey. If you have trouble finding it,
email me privately and I can get one for you.
