Something is off with temperature sensing in the bottom part of the refrigerator compartment, a zone LG labels R2. The cooling system then performs below its normal level, and the manual’s answer is to request service.
Models with LED panels
On analog display models LG treats the matching sensor errors the same way. A professional inspection is needed, and the technician examines how each sensor is connected.
Where r2 sits among other codes
The top half of that compartment is covered by rS. Another r-code, rF, concerns the refrigerator fan, while Lo is only a cold-room warning.
San Francisco refrigerator repair for r2
Call (415) 223-7887 if r2 will not go away. San Francisco and Bay Area callers should give the model number and say exactly what the display reads. The LG refrigerator repair page has the overview.
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
An anomaly in temperature detection on the lower refrigerator side (R2) reduces the appliance performance.
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.
