3Before repairMake sure to cut off the power line before disassembly, parts replacement and assembly.Otherwise, electrical shock or injury may occur.Be careful of electrical shocksBe careful of electric shock from live parts or electrical lead terminals when conducting voltage measurement and otherelectrical servicing.Voltage of the control board is approximately 280V when power is ON.Do not touch live parts.When replacing parts, do not touch live parts for at least 3 minutes after disconnecting the plug from the power supply.(A little time is required for electrical discharge of the condenser)Use only fuses specifiedWhen replacing fuses, use only specified in the circuit diagram. The use of non-specific fuses may cause fire ormalfunction.Punch the pipes of the faulty compressor securely.Otherwise, the refrigerant remaining in the compressor oil might leak out during transporting and could catch fire andexplode.Discharge refrigerant completely from the used service can for disposal in an outdoor place where thereis no fire source.Otherwise, you could run the risk of fire/explosion.Do not damage the refrigeration circuit (piping) of the refrigerator.As the refrigerant is flammable, any damage could lead to fire/explosion.If the refrigeration circuit is damaged, do not touch the refrigerator or use a naked flame.
