Comfee Humidity Sensor Error (Alternate Code)

Dehumidifier displays F2 and stops dehumidifying; fan may still operate.

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 or shorted humidity sensor, Contaminated sensor element, Loose connector on humidity sensor harness, Faulty humidity processing circuit on PCB

Safety: Unplug the unit before removing the front grille.

Clean sensor: Access the humidity sensor module behind the front grille and gently clean dust from its vents.
Check wiring: Ensure the sensor harness is intact and firmly connected to the main PCB.
Replace sensor: If F2 persists, replace the humidity sensor module with the correct Comfee part.
Control board: If a new sensor does not resolve F2, the main PCB likely needs replacement.
