C465Comp V_limit/I_limit error
Name in the manufacturer's documentation (service manual): Comp V_limit/I_limit error
[1]
In plain words (editorial)
The compressor hit its voltage or current limit. The service manual first asks whether the outdoor unit is installed properly (obstacles removed), whether the high-pressure service valve is open and whether the refrigerant is overcharged; after waiting a moment, the unit can be tried again.
When to call a service technician: Remove any obstacles around the outdoor unit; if the error returns, contact an authorised Samsung service technician.
