Aprilaire 700 humidifier not adding any humidity

I have a Aprilaire 700 humidifier which worked fine when it was new 3 years ago. However, now it does not seem to add any humidity to our house. I replaced the water panel and the distribution tray. I do see water in the distribution tray. I can hear the humidifier fan coming on and I can feel it sucking air when the furnace blower comes on. I can also see water coming out of the humidifier drain (dripping). My guess is that it is not drawing water at it's full capacity and somehow the water flow is restricted by the electronic module. I do not see any clogging of the incoming water line. Can someone help me with this? Is there a way I can see how fast it is drawing water when it comes on?

Thanks for your Question,
Sounds to me like you have a calcium build up in the Solenoid, which is restricting flow to the unit for proper operation, you might even have a bit of restriction in the copper line feeding the Solenoid, replacement of the solenoid would probably take care of your problem, one quick tip, in the spring and summer months, its a good idea to shut the water off to the unit, this should make the Solenoid last a little longer, hope this was helpful to ya, please let me know, thanks again,

Have you measured the quantity of water coming out of the drain tube? It should meet the specification of 1 quart in 2 and half minutes. I had the same problem and noticed the water output from the drain was only 3 ounces in that time. I got the contractor to replace the solenoid on warranty and it now gives me the specified drain water. This is of course only one of the possible reasons. Also time how long your furnace runs in an hour at a particular temperature. The specification for the Model 700 is 35% at 70% activity. Mine runs at 50% with external temperature of 30 F. For the most part I get 33% but when the humidity is high outside (low difference between temperature and Dew Point) it gives me 36%.

Aprilaire 700. It works on fan on mode but not otherwise. It's never on and the humidity reading is always way below the setting. It should turn on automatically to bring the humidity up, right?


It appears your Aprilaire model 700 is wired to only operate when your HVAC fan is operated by your thermostat. Your HVAC installer can wire the humidifier control to operate the humidifier during a heat call, fan call or to turn on the fan when there is a need for humidification. Please contact your HVAC installer to have them change the wiring.

When the system calls for heat My Aprilaire 700 fan turns on, but the solenoid doesn't open up. The indoor humidity is around 35% now, outside temperature was around 35 with relative humidity of 75%. In...


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

if it comes on when turned to RESET then its probably fine. The humidity may be higher than the highest setting on the stat. If you leave it on test reset it will not work .

Aprilaire Model 700 - not achieving 40% humidity


if it is set up right, you should be able to run your fan 100% of the time and the humidifier will come on when there is a need for humidity. you can experiment with leaving the fan on and see if this helps. it will run your electric bill up a little and also you will have a lot of waste water. that is a drawback to the bypass type humidifiers. also a factor is if the water supply is hooked up to the hot or cold side. it will humidify better on the hot side, but you tend to get more deposits that plug the solenoid over time and you will be running your water heater quite a bit. 1600 sqft may be pushing the limit of this humidifier.

are you having problems with your fan blade rotating in the wrong direction? Is yours pushing or pulling water through the water panel? I am very unhappy with my humidity levels in my house.
