When it stops, ice production falls off or stops entirely while the rest of the machine looks perfect — which is why this arrives as a no-ice call rather than a cooling call. LG puts a sensor on the fan so the machine reports the blockage rather than leaving you to work out why the bucket is empty. The usual cause is the same as everywhere else in this trade: ice where the air should be. ### The other ways LG prints this one IF · Er IF 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 - Take the ice bucket out and look into the bay with a torch. A visible collar of frost around the fan is the answer. - Check the door is closing squarely and the bucket is seated. A door held open a fraction feeds warm wet air straight into this compartment. - Turn the ice maker off, let the bay defrost overnight with the bucket out, and turn it back on. - If the code returns after a proper defrost, the fan or its sensor is the repair. ### 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.
