How to troubleshoot common Honeywell humidifier problems

*   Unit not humidifying. If your Honeywell humidifier isn't running, and the humidity is below the desired setting, the humidity control may have a frost protection setting. The frost protection system limits humidity output based on outdoor conditions. For example, on colder days, the air in your home can hold less humidity. The frost protection system automatically lowers the humidity set point accordingly, to prevent frost from appearing on the inside of your windows. Check your owner's manual for more information about the frost protection system on your Honeywell humidifier. Also, your Honeywell humidifier won't humidify while the unit is in an automatic flush cycle.
*   High humidity. Adjust the humidity setting to the desired humidity level in your home. Unplug the humidifier and replace the control if high humidity persists.
*   Humidifier won't run at all. Check power going to your humidifier. Make sure its power cord is plugged into a working outlet. Reset the house circuit breaker for the outlet if the outlet doesn't have power. Unplug the humidifier and check the power cord wiring connections to the control. Reconnect any loose wires. Replace the power cord if it's damaged. You may need to replace the control if it's getting power but the humidifier won't run.
