Six Common Humidifier Problems:
Unit Switch is Off
Your humidifier switch or circuit breaker might be in the off position! Check your on/off switch!
Filter or Water Line is Clogged
Most units work when water is supplied and converted into water vapor through evaporation or steam. The water lines or injectors can clog especially with hard unfiltered water.
In evaporative units, the water filter panel will accumulate dust and mineral residue reducing or preventing proper vaporization. Periodic and seasonal cleaning and replacement (of disposable) filter panels will keep your evaporative and hot water diffusion units functioning properly. Hot water vaporizer units tend to clog more often with hard water deposits. Note: A main line water softener unit from brands such as Rainsoft, Whirlpool, Aquasure, will alleviate this problem altogether, and provide healthier water for household use.
Check Damper Position
Many units have a damper located where the unit attaches to the ductwork. This may be closed during the summer months to avoid air pressure loss. If the unit is started with the damper still closed, the moisture will not disperse into the ductwork. Set a reminder or calendar appointment on your smartphone to remind you check this when doing your winter maintenance.
Water Line Shut Off
The shut off valve to the water line may still be turned off from the end of winter season when the humidifier is turned off. Remember to open this valve as the unit will not work without water. Note: check for any water line leaks as shut off valves can be a source of failure.
