Possible Causes

Out-of-range humidity or temperature sensor readings, Loose sensor connectors, Corrupted sensor calibration data on PCB

How to Fix / Troubleshooting

Safety: Unplug the unit before accessing internal components.

Steps:

  • Power reset: Disconnect power for 10–15 minutes, then reconnect. Sometimes F0 clears after a full reset.
  • Check sensors: Inspect both the ambient NTC sensor and humidity sensor connections on the main PCB. Reseat connectors firmly.
  • Clean humidity sensor: If accessible, gently clean the humidity sensor area with dry air to remove dust.
  • Board-level reset (if supported): Some Argo models allow a factory reset via button combination (consult service literature). Perform the reset to reload calibration values.
  • Replace faulty components: If F0 persists, replace the Argo digital humidity sensor module first. If still unresolved, replace the Argo main control PCB.
