Most field problems come from water level, water quality, wiring, airflow or maintenance interval rather than the module alone.
Check water depth, scale on the discs, driver voltage and whether airflow is pulling mist away from the outlet.
Confirm the float switch, water level protection and driver connection. Intermittent wiring faults can look like module failure.
Hard water, dry running and poor heat dissipation shorten disc and PCB life. These should be controlled in the tank design.
Project note: When reporting a problem, send photos of installation, water depth, driver label, running hours and water quality. It is faster than only describing the symptom.
