Reading an LG model number
LG model numbers look cryptic, but once you can read the prefix you can identify the appliance, the technology inside and the parts a repair will need. The first letters name the family — WM and WT for washers, DLEX/DLGX/DLHC for dryers, LDF/LDP/LDT for dishwashers, LR and LF for refrigerators, LRGL/LREL/LSEL for ranges, WSEP/WDEP for wall ovens, and LMV/LMC for microwaves. The trailing letters encode finish and configuration. Browse the families from the appliances overview or jump into the model library.
Laundry model families
Washers use WM for front-load (WM4000HBA, WM4500HBA, WM5500HVA, WM6500HBA, WM6700HBA) and WT for top-load (WT7900HBA, WT7400CV, WT8405CW); the stacked WashTower carries the WK prefix (WKEX200HBA electric, WKGX201HBA gas, WKHC202HBA heat-pump). Dryers split by heat source: DLEX electric vented (DLEX4000B, DLEX7900BE), DLGX gas vented (DLGX4001B, DLGX5501W), and DLHC ventless heat-pump (DLHC5502W, DLHC1455W). Service starts at washer repair or dryer repair.
Refrigeration model families
Refrigerators mostly use the LR prefix — French-door (LRFVS3006S, LRFXC2606S), side-by-side (LRSXS2706V), top-freezer (LTCS20020S) and InstaView (LRYKS3106S, LMXS28626S) — while LF marks certain models such as LF29H8330S (which has no InstaView). The ultra-premium LG SIGNATURE fridges take a U prefix (URNTS3106N, URNTC2306N, LUPXS3186N). Upright freezers use LROFC (LROFC0605V, LROFC1104V), and the SIGNATURE wine cooler is the single URETC1408N. Service begins at refrigerator repair, freezer repair or wine cooler repair.
Cooking model families
Ranges read by fuel and style: LRGL gas (LRGL5825F, LRGL5823S), LREL electric (LREL6325F), LSEL electric slide-in (LSEL6337F, LSEL6335FE), LSGL gas slide-in (LSGL6335F), LSDL dual-fuel (LSDL6336F) and LTEL double-oven (LTEL7337F). Wall ovens use WSEP single (WSEP4727F) and WDEP double (WDEP9427F), with the combo WCEP6423F adding a microwave; LG wall ovens are electric. Cooktops split into electric LSCE, induction CBIH/CBIS and gas LCG/LSCG/CBGS. Microwaves carry LMV OTR (LMV2031ST) and LMC countertop NeoChef (LMC2075ST). Service starts at range repair, oven repair, cooktop repair or microwave repair.
Dishwashers and range hoods
Dishwashers use LDF, LDP and LDT (LDFN4542S, LDPH5554S, LDTH7972S), with the LG STUDIO LSDTS9882S the quietest at 40 dBA. Range hoods carry the LG STUDIO LSHD prefix (LSHD3080ST 30-inch 600 CFM, LSHD3680ST 36-inch), wall-mount chimney style only. Because both install into a fixed opening, the model number tells a technician the width and configuration before arrival. Service begins at dishwasher repair or range hood repair.
Product lines and finishes
Beyond the family prefix, an LG appliance belongs to one of three honest product lines that shape how it looks and what it costs to keep: LG, the mainline core lineup that covers the bulk of models; LG STUDIO, the premium designer tier with built-in fridges, wall ovens, ranges, cooktops, range hoods and the quietest dishwasher; and LG SIGNATURE, the flagship tier including the U-prefix refrigerators and the URETC wine column. The finish letters at the end of a model string look like a typo but encode the color and trim, which is why a technician needs the complete model number rather than just the prefix — two units that share a prefix can take different panels or hardware.
Decoding and servicing your model
An LG model number combines the family prefix, a capacity or width number and a finish suffix — reading all of it identifies the exact build. The rating plate is usually on an interior side wall, along a door jamb, behind a drawer or crisper, or on the underside of a cooktop; record the full string before you book. If your appliance is showing a problem, start with the error-code library, then match the family above. Our experienced technicians service every LG family regardless of age, using genuine parts matched to the build, and specifications can be confirmed on the manufacturer’s site at lg.com/us. When you have your model in hand, schedule a repair — pricing starts from a clear diagnostic fee, with the final cost depending on the parts and configuration, and our labor is guaranteed.
