LG FRIDGE LRFDS3016 Not Cooling

Universal Linear Compressor Kit

This model utilizes an Inverter Linear Compressor which has a known high failure rate due to internal mechanical fatigue of the suction and discharge valves. When these valves fail, the compressor runs but fails to generate the necessary pressure for the refrigeration cycle. The universal kit includes the necessary software update/JIG to ensure compatibility with the existing PCB.

Evaporator Fan Motor

Search data specifically identifies issues with the cooler evaporator motor on this model. If the motor's bearings seize or the internal hall effect sensor fails, air is not pulled across the evaporator coils, preventing the refrigerator and freezer from reaching set temperatures even if the compressor is functional.

Main Power Control Board (PCB)

The PCB contains the inverter circuitry that drives the compressor. Voltage fluctuations or heat-induced solder joint failure on the inverter drive section can prevent the compressor from starting. This is the primary diagnostic point if the compressor shows correct resistance but fail to initiate a start-up hum.
