Humidifier not working
Brand:Bemis

Product:Humidifier
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 - Drive Motor
Drum-style humidifiers use a drive motor to rotate the drum through the water in the tray. If you’ve confirmed the drive motor is receiving voltage, but the drum is not turning, it’s likely the drive motor is defective. You can use a multimeter to test the motor for electrical continuity to help determine if the component is faulty or not. If the motor tests negative for continuity, you’ll know the motor has failed and will need to be replaced with a new one.
Common
03 - 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
04 - 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
05 - 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.
