What it means
FO means the unit is in refrigerant-recovery or pump-down mode. The GREE service manual describes this as a maintenance mode, not a normal homeowner error display.
Urgency
Not an error
This is a normal status indication, not an error, unless comfort is poor, water is present, or the indication never clears.
Likely causes
Homeowner fix
If a technician intentionally placed the unit in this mode, let them finish. If FO appeared unexpectedly, turn the system off from the remote and call the installer before running normal heating or cooling.
When to call a pro
Call a licensed HVAC technician if FO appears when no one is servicing the system or the unit will not leave the mode. Tell them the display is refrigerant-recovery mode.
Repair vs replace
This is a normal operating status, not a repair-or-replace decision.
