Humidifier usually runs when heating mode is active.
If you checked when it was running in heat mode,
then two things to check, water supply solenoid valve is
burnt out or jammed, or there is no power to humidistat
which is 24V AC voltage. Good luck.

You're not giving us much to go on. I suggested you set it to test and
listen for a click from the valve. If you move the control from min hum
setting all the way to test, it should be clicking on and off. Does it?
Are LEDs on the control lit, ie it's getting power? You should try the
clicking test with the furnace firing. I think most are wired so that
the test may work even with it off, but doing that test you should hear
there is no test on this humidistat, nor is there leds. i turned it all the way up, while the furnace was fireing. then slowly turned it down till the click. Nothing.
I have tried to do what everyone has suggested. there is just simply, no water moving through the humidifier.

I just lookded at the manual for the 600. The automatic version that
includes outside temp compensation has a humidistat that has the test
position. The humidistat for the one without temp compensation has a
simpler control with no test position, which isn't a good thing. It
doesn't look like it has any indicator LEDs either. Sounds like that's
the one you have.
Do you know what the humidity in the house actually is? If the house
is on the dry side and the unit won't click on when it's set to max,
then something is wrong.

Just to be clear, there are two valves.
They are typically installed with a saddle valve that clamps to a water
pipe. That valve, as most do, opens counter-clockwise.
The other valve is solenoid actuated and is located on the humdifier itself.
If you have no click sound coming from the solenoid valve when the humidifier
tries to go on, then water isn't the problem.
And btw, if he used plastic tubing, he should have used copper. Plastic
tubing will spring a leak in a few years and spray water all over the
area until you notice it. I guess some humitifers come with plastic
You said it is a brand new install and hasn't worked from the get-go. Who
did the installation -- you, a friend, or a company that you paid for the
installation? If it's a company or person that you paid, have them come
back out and show you that it is working, or fix it so it does work -- since
it has never worked for you since it was installed.
Also, when you post messages here, are you able to quote the message that
