Aprilaire 550 humidifier

I sent my husband to get a new filter for an aprilaire 550 filter. He took the frame the filter sits in and everything attached. He threw the hole thing away. What parts do we need to put this back together without haveing to put a new system in.

What controls how much water flows into an Aprilaire 550? It was fine until a couple of days ago. I replaced filter, but it still appears to be too strong. It not only runs out the drain tube but is...

In the water line where it connects to the solenoid is an orifice. You can install a smaller plastic orifice or you can install a manual feed valve to where you can control the flow.

Have solenoid: MOPD 125, WATT 2.3, VOLT 24/60, for Aprilaire 560 Humidifier. With a M15 Universal tester using 150mA for + & K OHMS FOR -, I get 2 ohms on scale which would be approx 200 ohms. Ohms = Volts...

I am guessing you have sent 24 volts to the solenoid directly and the the solenoid did not activate?

If you have not send power directly

If the solenoid does not activate that way more then likely needs a new solenoid.

It has been awhile since i removed my water pad and forgot how to route water line in pad

I've got a 560A, but if it's similar:  The pad sits in a plastic frame with the drain hole and "funnel" at the bottom.  At the top of the frame, there's a plastic piece that sits at the top of the pad; it snaps into the frame and the frame snaps into the humidifier housing.  The water tube from the solenoid slides into this plastic piece so that the water is directed to the top of the pad.
