Having a problem with your humidifier?

Below are listed some procedures for troubleshooting humidifier water problems:

I see problems ever now and then with humidifiers where the water will not flow, or the water will not stop running, even when the humidifier is turned off. In many cases it could be a bad water solenoid valve. Check the following before condemning the water solenoid valve.

bullet

Make sure the water saddle valve is not restricted by turning the saddle valve on. Loosen the compression nut slightly where the 1/4" copper tubing enters the saddle valve. If water comes out then your saddle valve is not clogged, and is OK. If there is no water coming out then you will need to replace your saddle valve.

bullet

Take the compression nut loose on the end of the solenoid valve that exits up to the water distribution tray (not the end where the water supply copper tube enters). After you take the tube off you should see a tiny plastic orifice up inside the tubing. Lots of time I see the orifice stopped up with lime deposits. The orifices are sold in the Aprilaire Humidifier links below. This will definitely cause the water to not flow in your humidifier. You can take a thin needle and reopen the hole or purchase another orifice to eliminate this problem.

bullet

If you water flow continuously and will not shut off when the blower stops you probably need a new water solenoid valve. You can check to see if it is the solenoid valve or an electrical malfunction problem by turning your furnace power off or unplug your humidifier. If the water continues to flow with the power off then you definitely need one of the Aprilaire 4040 valves listed for sale in the Aprilaire Humidifier links below.

Humidifier Installation Accessories:

Below are listed some of the accessories and supplies you might need when installing your humidifier.

One accessory that I use on many of my humidifier installations is a Current Sensing Relay. This nifty little relay allows me to quickly set up the humidifier to run only when the furnace blower is running. This eliminates the need for a sail switch or more complex wiring. The relay attaches around the white (most of the time) common lead of your furnace blower motor. When the blower comes on it senses there is current and turns your humidifier on. It is easy to install and comes with complete wiring directions and instructions. The A50 current sensing relay acts like a 24 volt switch. The A50 is not designed for 110 volts. You would need the A51 current sensing relay if you plan on running 110 volts through the relay.
