C484PFC over load error

Name in the manufacturer's documentation (service manual): PFC over load error[1]

In plain words (editorial)

PFC overload error. The service manual's first step is to power the unit on again 30 seconds after switching it off; it then checks for obstacles at the inlets and outlets of the indoor and outdoor units, the service valves and the compressor.

When to call a service technician: Remove obstacles around the units; if the error returns, contact an authorised Samsung service technician.
