LG’s own note places it in the upper part of the refrigerator section. The practical effect is a cabinet that cannot aim — it will hold something, but not the number on the display, and it will often swing rather than sit. If you have been chasing a fresh food compartment that is too cold at the back and too warm at the front for weeks, this is the code that explains it. ### The other ways LG prints this one rS · Er rS · r rS · R1 LG publishes a condition and then every string that can stand for it, and which one your machine shows depends on the panel it was built with — OE, E03 and E21 are one condition on a washer, and Er dS, F dS and r dS are one sensor on different evaporators. They are one page here, so whichever of them you searched for, this is the right page. ### Where this appears, and why not to clear it On the appliance’s own display. LG reports errors two ways: machines with a digital display show a code, and the laundry machines without one blink their indicator lights instead. Both are published by the maker and both are on this site. Photograph what the panel shows before cutting the power. On a refrigerator you can also force the last code back onto the display by holding Freezer Temperature and Express Frz together for three seconds — LG documents that, and it is the one thing that makes a first visit more useful. A code that has been reset is information a technician no longer has. ### What to do about it - Note whether the freezer is still behaving. A good freezer with a wandering refrigerator narrows it usefully. - Cycle the power for five minutes and see whether the code returns. - Measure the compartment with a thermometer at the middle shelf rather than trusting the display. - Book the visit. A sensor is a part, not a rebuild, and the machine will keep mis-cooling until it is replaced. ### Where this goes next The job this usually becomes is [diagnostic visit](/services/diagnostic-visit/), and that page carries a starting figure and the reasons that move it. If it turns out to be nothing — and on this make a real share of these are modes, reminders and settings rather than problems — the visit ends there and you pay the diagnostic and nothing else, or call [(305) 419-0291](tel:+13054190291) and describe what the panel is doing before booking anything.
