How to Find the Model Number on Any LG Appliance — All 6 Types

Exact label locations for every LG appliance type, with pro tips for faded or hidden stickers. Refrigerators: upper-left interior wall (French-door models) or door jamb (top-freezer models) — never on the exterior. Dishwashers: bottom edge of the inner door panel when fully open, facing outward. Front-load washers (WM series): front panel ring around the drum opening, roughly at the 8-to-10-o'clock position. Top-load washers (WT series): underside of the lid. Dryers (DLE/DLG): right-hand panel inside the door opening. Ranges and wall ovens (LRG, LRE, LSG): left side of the oven door frame or the face of the storage/broiler drawer. Also covers how to read LG model number prefixes (WM vs WT, DLE vs DLG, finish suffixes W/S/V/K) and how LG serial numbers encode manufacture year and month in their first three digits.
