No water flowing onto the pad

Possible causes:

Water supply off.

Solenoid not receiving electrical signal to open.

Solenoid bustimicated.

Outlet orifice clogged with mineral deposits.

Caveat: experience with another aprilaire unit, and I didn't look up your unit specifically.

There is also a fine screen filter on the incoming side of the
solenoid. But to get it out, you usually wind up trashing it, so you
should have a spare. Arnold Service Co on the internet sells them as
well as the orifice. I'd start by measuring the voltage on the
solenoid, or listening for it to click.
