Re: my humidfier is not working
Is the water on ? if it is you will need to use a multimeter to test to see if you have 120 volts at the transformer, 24 volts from the transformer to the solenoid, make sure you have the low voltage wiring completing a circuit from the transformer, to the solenoid, from the solenoid to the humidistat, humidistat to the transformer again, make sure your transformer is hooked in to only receive power when you are calling for heat, thats about it, hope that helped ya, and thanks for your question, let us know if that helped, thanks again, mr.grzz

first its important to understand how humidifiers work ,
they work by using a pressurized source of water (prefer demineralized) that enters a chamber that has a device that wicks the water up into it , then a fan induces a draft across it , this produces evaporation of the water into the air flow , this air is then ducted into the air handler for the structure (home?)
now that being said the water chamber needs constant refilling due to evaporation of water from air flow , most times this is handled from a solenoid valve that is basically an electric operated valve , and yes it's logical that it could be tied to a humidistat for demand use only .
also this type of humidifier requires frequent cleaning or it may back up and spill water in the wrong places ,especially if there isn't a demineralizing filter on water line , as the minerals that naturally occur in water don't evaporate and get left inside the chamber , making less and less room for new water to be added
Hello, if there is water to the solenoid valve but not passing through it than the solenoid valve is malfunctioning and must be replaced. However, if there is no water at the solenoid valve then either the saddle valve or supply line is clogged with sediment. A easy way to chek the solenoid valve is apply power directy to the solenoid valve from the transformer, if it does not open then replace it.
I have same problem with no water flow on identical humidifier but was able to fix it. Removed the inlet to the solenoid valve and found (1) a small taper mesh filter inside (2) a small diameter orifice that was clogged. Cleaned the miniature filter and used a sewing needle to open the orifice and now works perfectly.
If the water continues runs nonstop even when the heater is turned off, you might have either a bad solenoid valve or a bad humidistat. Simply disconnect one of the two low voltage wires going into the unit. If the water turns off then your problem is most likely your humidistat or the low voltage wiring. If the water continues to run even when the low voltage is disconnected you have a defective solenoid valve.
Hi John Your whole question did not show up (maybe you can re-post) . I can answer what part i understand though. If the humidifier was wired in right it will not send power to the humidifier until the furnace is on, and calling for heat. This stops the unit from working in the cooling mode in summer.Make sure your furnace filter is clean as well
the change water panel light is just a timer. it does not sense that the water panel actually needs to be replaced. sounds like you have a solenoid issue. if you have water to the solenoid and are certain you are getting 24v to it, the solenoid is ethier bad or plugged with calcium. most likely calcium. sometimes you can take them apart and clean them. so, it you can hear clicking at the solenoid when you turn the humidstat up and down. try cleaning it.
Turn that pin to the left and that will open the valve to allow water to flow through it. If it starts to leak the all you need to do is tighten the nut that were the water is coming out with a wrench, be carefull it wont take much to tighten.
