Common solutions for: Humidifier not working

01 - 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.

02 - Humidistat

The contacts in the humidistat should close when the dial is set higher than the actual humidity in the room. You can use a multimeter to confirm the humidistat contacts are closing. If the contacts do not close as expected, the humidistat is defective and should be replaced.

Common

03 - Water supply valve turned off

Confirm the water supply shut off valve is in the on position. You may have to rotate or pull a knob or move a lever to open and shut the valve. You can follow the water line from the humidifier's water inlet valve to find the water supply valve.

Less Common

04 - Humidistat turned off or not set properly

If your humidifier is not working, first verify that the humidistat is on and set properly. If there is a on/off switch, make sure it's turned on. A normal comfortable humidity range in a home is between 40% to 50%. Refer to owner's manual for guidance.
