Why doesn't my humidifier work at all?
To avoid personal injury or death, disconnect your appliance from its power source before you start any troubleshooting or repair work. Use caution when working inside any appliance.
A humidifierТs main control feature is a humidistat. If itТs not functioning properly, it wonТt let your humidifier work. Other problems could include a valve, motor, or transformer. Whenever your furnace or air conditioning unit is running, your humidifier should run as well. Most humidifiers work by evaporation.
