LG Refrigerator (French Door) rS error code

Difficulty: Hard · Cost: $80–$200 · Duration: Requires professional service

The rS error means your LG refrigerator has detected a fault with the refrigerator compartment sensor — the component that monitors the temperature inside the main fridge section. Without an accurate temperature reading the refrigerator cannot regulate cooling properly, which risks food spoilage. This is similar to the FS error but affects the refrigerator section rather than the freezer. A reset may temporarily clear it but a returning rS error means the sensor or its wiring needs to be replaced by a technician.

Common causes

  • Refrigerator compartment temperature sensor has developed a short circuit
  • Sensor wiring has become disconnected or damaged
  • Refrigerator sensor has malfunctioned or failed completely

How to fix it

  1. 1

    Unplug the refrigerator from the outlet and wait 5 minutes

  2. 2

    Plug it back in and check if the error has cleared

  3. 3

    If rS returns after resetting the refrigerator sensor or its wiring needs inspection and replacement by a technician
