Lennox Humidifier not getting water

Common solutions for: Lennox Humidifier not getting water

01 - Water Inlet Valve
The water inlet valve is an electrically-controlled valve that opens to allow water to enter the humidifier. If the water inlet valve is clogged or defective, the humidifer will not fill with water. Use a multimeter to test the valve for continuity. If the water inlet valve does not have continuity, replace it. In addition, test the incoming power to the valve. If the water inlet valve has continuity and is getting power, but the humidifier won't fill with water, it is possible that the valve is... clogged. If the water inlet valve is clogged, replace it.

02 - Clogged Saddle Valve
The saddle valve is a small brass water supply valve which is often clamped to a copper household water supply pipe. Over time, the saddle valve can become clogged with sediment or calcium deposits. Because it is difficult to clean a saddle valve thoroughly, and because the replacement cost is fairly low, we recommend replacing the saddle valve if it is restricted.
03 - Humidistat
If the humidistat is incorrectly set or isn't working properly, the humidifier won't fill with water. To determine if the humidistat is defective, turn the humidistat to the highest setting and listen for a "click." If you do not hear a click, this indicates that the electrical contacts inside the humidistat are not closing. If you do hear a click, but the humidifier still won't fill with water, it is more likely that another part is defective.
