Hi, it could well be the compressor has overheated or the motor protector module is faulty (if that model has one)

does it have phase protection??- swap phases over in case compressors running backwards

Power source quality could be a issue!
Check voltages, voltage drop and balance of phases!

What about the refrigeration charge? Is it charged by factory with HFC or nitrogen?
