What to do if my NANO Dehumidifier is not cycling?
- JJoyce BrooksAug 8, 2025
If your NANO Dehumidifier isn't cycling, first ensure the controller is powered and check the on-screen column status to confirm it's powering the solenoid valves during normal operation. Also, check the power to the unit and the fuse (T2A 250V) located at Fig 8.A. Insufficient inlet pressure could also be the culprit; ensure it's at least 4 barg and adjust the inlet pressure settings if needed. A failure to de-pressurize during cycling could indicate a solenoid valve malfunction. If the coil has power, replace the valve. A working valve should produce an audible click when energized. Finally, check the inlet air supply if the outlet flow stops.
