Devola Humidifier Short Cycling / Overheat or Level Misread

Devola humidifier turns on but shuts off after a few minutes even with sufficient water.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Overheat sensor tripping, blocked air vents, faulty water level sensor intermittently opening, failing power supply on PCB

Safety: Unplug before inspection.

Ventilation: Ensure the humidifier has adequate space around it and vents are not blocked.
Clean internals: Remove dust from vents and internal fan.
Check water level sensor: Inspect the float or level sensor for free movement and secure wiring.
PCB diagnosis: If the unit still shuts off randomly, the power supply or overheat circuit on the PCB may be failing and the board should be replaced.
