LG Refrigerator Error Code Er FS: Meaning and Fix

Also shown as: E FS
Reading the refrigerator display
On a refrigerator the code shows on the control panel or dispenser display. Some models flash a letter or alternate two characters; hold the code in view and note both. LG codes are short letter pairs; a capital O differs from a zero.
LG appliances show short alphabetic codes (OE, IE, UE on washers, Er plus letters on refrigerators) and, on ThinQ models, a Smart Diagnosis option. LG also builds many Kenmore Elite units. The codes apply to model numbers such as LDF7774ST, LDT5678SS and DLEX3900B; check the label on your unit to confirm yours.
