LG and Arçelik Inverter AC Outdoor Unit DC Fan Motor - EAU57945710 / SIC-67FV-F143-5 (DC 310V, CCW)

The high-performance EAU57945710 / SIC-67FV-F143-5 DC Fan Motor, which ensures efficient and quiet operation of the outdoor unit in inverter air conditioning systems, is offered in original spare part quality. With an operating voltage of DC 310V and counter-clockwise (CCW) rotation, this motor optimizes heat transfer in the outdoor unit and keeps the cooling and heating performance of your air conditioner at the highest level.

High Energy Efficiency and Quiet Operation

Consuming much less energy than conventional AC motors, this DC inverter motor adjusts its speed to the instantaneous demand of your air conditioner thanks to its precise speed control (frequency conversion) capability. This smart operating principle both saves electricity and minimizes the noise level of the outdoor unit. Its housing, resistant to severe weather conditions and high operating temperatures, promises many years of trouble-free use.

Practical Installation and Replacement Note for Field Technicians

Technician Note: For outdoor unit fan motor faults (especially when a motor lock or socket feedback error such as CH67 appears), always switch off the main breaker of the air conditioner before replacement. Since DC 310V is high voltage, wait for the capacitors on the board to discharge completely. When fitting the new motor, make sure the fan blade sits fully in its seat on the shaft and the nut is not left loose. Also, when plugging the motor's 5-pin socket into the board, do not neglect to check for corrosion and confirm that the socket is fully seated.
