LG microwave codes
On a microwave the code replaces the clock on the display. Unplug the unit for a minute to see if it clears, and note the code before you do. LG codes are short letter pairs; a capital O differs from a zero.
Models covered: LMC1575ST, LMV1680ST, MSER0990S, MH1536GIS, LMV2057ST.

About LG codes
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.
