Humidifier Water Inlet Valve Not Flowing?

Hey guys,

My humidifier inlet valve/solenoid valve hasnt been flowing water for a few days. Dismantled the assembly and i have water going to the top of the valve but it does not pass through. Im thinking the obvious, valve is shot but is there another answer to this issue? Any help would be appreciated

Have you verified it’s getting proper power?

yes, check power first.

Also is your furnace running, heat on and blowing and humidity turned on high so the solenoid should be open?

Solenoid is cheap and easy enough to replace.

Step 1 : Set furnace temp higher by 3 C so that it comes ON.
Step 2: Turn the dial of your humidistat to max.
Step 3: Do you hear click sound when furnace turns on and solenoid is energized? If Yes than it means you have power going to it but its not physically opening.
If you do not hear click sound :
Step A : Check the poer where yellow wires from your humidistat are connected ? If there is no power than check if you are getting power to the humidistat. If still the answer is no than check if the outgoing source is giving power at all ?
No power going to humidistat can be cuased by either faulty transformer or the terminal on board itself.
