Dimplex Humidifier Fan Motor Failure

Humidifier display and buttons work but fan does not run (evaporative models)

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

Open fan motor winding, Obstructed fan blade, Failed fan driver on PCB

Safety: Unplug the humidifier before opening the housing.

Steps:

Access the fan motor and check for obstructions. Remove any debris.
Spin the fan by hand; if stiff, the motor bearings may be seized and the motor should be replaced.
Test the motor windings for continuity. Replace the fan motor assembly if open.
If the motor tests good but does not receive voltage when commanded on, the main PCB fan driver is likely faulty and the board should be replaced.
