Question about Aprilaire 700 Humidifier
So I turned my humidifier on (aprilaire model # 700) for the first time since I moved into the home (03/07). At first when it came on it was leaking water everywhere. I popped off the cover and cleaned out the water panel (wire mesh) and plastic housings as best I could. I put it back together and fired it up again and no more leaks. However, the thing runs constantly (regardless if the gas furnace is running or not). I would assume the humidifier should not run when the furnace isn't working.
Thanks for your question,
Sounds to me like you have a bad solenoid valve in your Humidifier, this will need replaced, the solenoid is supposed to open and close when there is a call for humidity only when the furnace is running, then when the proper amount of humidity is sensed by the humidistat, then will it shut off, with the solenoid not working it will let water flow through like an open faucet, the solenoid is the componet that the 1/4in copper tubing connects to at the humidifier, has two wires running from it, you will need to shut the power off before changing this out, also shut the water off at the valve at the other end of the 1/4in copper line, or you might get soaked,please be careful when installing the new solenoid, making sure the water line connection is secure, or you will have leaks, hope this was helpful, please leave a rating, thanks again for your question,
