Quick answer
r2 signals a fault with temperature sensing on the refrigerator side, lower part (R2). Performance drops and service is requested.
Model compatibility: LG reuses codes across series and model years, so r2 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
r2 is an anomaly in temperature detection on the refrigerator side, lower part (R2), which reduces the appliance's performance.
An r2 on the display of an LG refrigerator tells you the temperature reading on the refrigerator side is off. The manual places the problem in the lower part, labelled R2, and says it reduces the appliance’s performance.
Next step
The listed action is to request service. For analog display models, LG describes the matching sensor errors as needing a professional inspection, and a technician checks the sensor connections.
Compare with these
rS covers the upper refrigerator-side sensor (R1).
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
