Worked LG washer example

This tested example preserves the serial result before applying model-era evidence.

Label Field What It Usually Means Why It Matters
Serial 412TATG1H105 Year digit 4; month 12 The serial returns December with candidate years 2004, 2014, or 2024.
Model WM3470HWA Known LG washer family context The current model evidence overlaps 2014 and narrows the tested result to December 2014.
Serial without model Three candidate years remain The decoder does not silently select the newest decade.

LG model and serial fields are not interchangeable

LG states that its product model numbers begin with a letter, while its appliance serial numbers begin with three digits. In the supported appliance path, those opening serial digits supply the year-cycle and month signal.

LG televisions and computer products have separate identification workflows. This page preselects the appliance decoder and should not be used to infer a TV date from a model number.

How to decode an LG serial number

Supported LG appliance serial numbers commonly use character 1 as the last digit of the year and characters 2-3 as the month. That makes the opening three characters the most important part of the serial for age checks.

What the model number can tell you

The model number helps confirm the product family, generation, and likely decade. That matters because the LG year position is a single digit, so the decoder may still need model-era context to resolve the final decade.

Common LG serial number formats

8-12 character LG appliance serials ~ Estimated decade. LG year digits repeat.
Year digit in character 1; month digits in characters 2-3

The opening digit and next two month digits usually drive the supported LG age estimate.

LG refrigerators ~ Estimated decade.
Same opening year/month pattern

Refrigerators commonly follow the same first-digit year and two-digit month logic.

LG laundry and kitchen products ~ Estimated decade.
Same opening year/month pattern

Washers, dryers, dishwashers, and ranges often use the same opening LG date structure.

FAQ

Which LG serial characters are used for appliance age? expand_more

The supported path reads character 1 as a repeating year digit and characters 2-3 as a two-digit month.

Why does an LG serial return three possible years? expand_more

The serial contains only the final year digit, so the same value can recur every decade. The model may narrow it only when verified era evidence exists.

How can I distinguish an LG model from a serial? expand_more

LG guidance says model numbers begin with a letter while appliance serial numbers begin with three digits. Record both fields exactly as labeled.

Does this page decode LG televisions? expand_more

No. It preselects the LG appliance path. Television model and serial research belongs in the electronics workflow.

Where is the LG refrigerator label? expand_more

LG identifies interior liner locations, commonly the right side on older models and the left side on newer refrigerators.

Where is the LG laundry label? expand_more

Front-load washer and dryer labels are commonly around the door opening; top-load washer locations can include under the lid, rear controls, or a side panel.
