Re: Water does not get to Humidifier. Goes from source to...
That is not a 'motor' on the side of the humidifier housing, it is a solenoid valve. The water feeds in to one side and exits the other side to a tube that feeds in to the top of the humidifier unit. The valve opens and allows water to flow when electrical power is applied to the valve
The valve electircal requirement may be either 120 vac or 24 vac. Power typically is switched on and off by a Humidistat control. The power feed to the Humidistat may come from a small transformer if the valve is a 24 vac unit, or directly from a furnace connection if the valve is a 120 vac unit. There are many variations, though.
A qualified licensed eletrician should check the power feed to the valve. If there is no power feed to the valve then he can trace back to the point of failure and correct the issue ... but he must also check for additional issues with the valve itself, as noted below.
Other possibles reasons for solenoid valve failure:
If power feed to the valve tests ok, then the coil inside the solenoid may be 'open' (bad, no continuity). The electrician can test the coil by checking resistance or continuity of the coil.
A non-electrical problem is that the valve path may be blocked by hardwater mineral build-up or other foreign material that flowed through the water line.
The solenoid valve must be replaced if either of the above is true with your valve.
Remember, use only a quailified licensed electrician!

Humidifier may be undersized or a restriction at the inlet side of the solinoiud valve. Turn water off to humidifier and remove inlet side of water line at the solinoid valve. Carefully remove the inline filter at the inlet side of the valve and wash under some warm water making sure it is clean.
I would first check to make sure you have water to incoming side of the solenoid valve. Most inlet and outlet fitting are compression type so you can carefully loosen nut on incoming side to see if you have water there.You don't want to take the nut off just back it off a liitle to see if you have pressure there.If so then retighten nut on incoming side and loosen nut on leaving side. Turn up thermostat to actuate solenoid valve.You should be able to hear a slight click when the valve opens.
If you have water on incoming side and you can tell that valve is working but you are not getting water flow then shut off water supply to humidifier and remove inlet nut and and slip pipe back to see if there is a blockage there. Clean as needed or replace solenoid if it's not working.If you have flow into unit but not out then check outlet side for blockage. I hope this helps . Thank you.
If you used the plastic tubing to the humidifier(I recomend copper) there should have been a little brass tube with a flare on it. This goes in the plastic tubing to grip the the sleeve better. See if this helps
Valves do go bad, but I had the same issue and it was the inlet orifice that was plugged. To fix: Turn off the water supply. Disconnect the water inlet line to the solenoid. The water inlet line connect to ~ 1" long piece that goes into the solenoid. Unscrew the water inlet piece and remove it from the solenoid. Check it for water flow - water should slowly drip out the small orifice at the soleniod side. There is a pin-hole sized orifice on the solenoid side and it doesn't take much to plug it. There is also a narrow cone-shaped filter inside the inlet piece. You can use tweezers to remove the filter and & use a safety pin or sewing needle to clear the orifice. Check the filter, clean it if necessary, and reinstall the filter. Now check for water flow thru the part before reinstalling. Reconnect the water inlet line and turn on the water supply. Turn your humidistat to trigger the humidifier. You should see water flowing through the drain tube.
do you hear a clicking at the solinoid? grab the solinoid and turn it on to see if its getting voltage, you should feel it energize. you can turn off the water supply and disconnect the water line from the solinoid. there is a black pre screen inside the inlet if you have a tiny flat heat screwdriver insert it into the inlet and turn it out. clean it and retry. you can also make sure the orifice isnt clogged its located on the outlet side of the soliniod. when you remove you will probably have a stream of water come out of the feed tube thru the orifice, even if it has sat all summer. if water comes out you dont have a clogged orifice. donot try to **** out the orifice if its clogged you will need to get a new one fron www.aprilaire.com . you can verify it clogged by after cleaning the prescreen reconnect the water line inlet and turn on humidifier if water comes thru the solinoid with the outlet feed tube not connected then the orifice is clogged. If you clean the prescreen and the orifice is fine ,still no water then you will need a new solinoid you should also be able to purchase from aprilaire. here is links to the solinoid and orifice
trace thre copper tube backwards to where it connects to main water line if there is a valve there open and close it if your not sure whats open or closed try it both ways there is also a little restriction device either on inlet or outlet of solenoid that may be clogged
Try the following test, ( I will resume this is a flow through humidifier)
Spray water directly oin the filter make sure it is saturated. Some water should leak from the bottom. After 10 min measure the Humidity to see if this helped. If there is a higher level of humidity the pbm is that not enough water is saturating the filter. Check the level of the filter & water feed nozzle.
Option 2 is to connect the water feed tube to a Hot water source.
Not sure what type of humidifier you have but if is a power humidifier like the April 700 or 760 they do have a blower motor and it may be the fan blade is broken.But if you have a bypass humidifier is posible that your water solenoid may be making noise because of to much water pressure there is not much to a bypass humidifier, you may want to close the water supply valve a little at a time se if the noise goes away.
A noisy humidifier may be the result of an unlubricated fan motor or a drive mechanism clogged by debris. Periodically clean the water reservoir, fan, and nozzle to ensure that they are clean and working properly. To keep your humidifier working smoothly and efficiently, lubricate the fan motor bearings with SAE #20 oil. Be sure to consult your owner?s manual for proper care and maintenance procedures.
If it seems loose, vibrating parts are causing the noise:
1) Disconnect the power.
2) Remove the cover and look for any vibrating parts. Tighten screws, if necessary.
3) Wiggle the fan to see if it is loose on its shaft. If it is, tighten the mounting fasteners. Lubricate the motor's bearings if suggested in your owner's manual.
4) If it still makes noise, call an appliance repairperson or take the unit into an appliance repair shop.
