LG LS23C4000V: LT120F refrigerator filter fit
For exact model label LS23C4000V, LG maps the refrigerator-air filter to LT120F. No water-filter family appears for this model in the captured map; that absence does not establish that the refrigerator has no water filter. Confirm the category and installed marking before ordering.
Safety boundary
- For removal and installation, follow the owner information for this exact refrigerator model; do not force a cartridge that does not seat normally.
- If the model label, filter category, or installed-filter marking disagrees with the locator result, stop and confirm the part with LG before installation.
- If water flow remains abnormal after confirming the model-correct water filter, consult the exact model manual or LG support; this page does not authorize internal plumbing or electrical service.
Compatibility requires a direct model listing, explicit supersession, or equivalent manufacturer evidence.
Models explicitly covered
These model identities have the source evidence listed below. Read the part decision and suffix limits before ordering.
Required identifiers
- Exact refrigerator model label: LS23C4000V
- Code printed on the currently installed filter
Compatibility rules
- Exact-model result: LG’s locator assigns LS23C4000V to air filter: LT120F. This assignment is the basis for the family choice on this page.
- Refrigerator-air decision: the mapped family is LT120F. LG says its air filter helps keep refrigerator air fresh by removing odor. Do not use a water-filter family as a substitute for this mapped air-filter choice.
- Before ordering, compare the complete appliance label and the installed filter’s printed marking against LG’s model result and the corresponding product page. A family match does not establish that every identifier variant listed on that family page fits this exact model.
- The captured locator map has no water-filter family entry for this exact model. This is not evidence that the refrigerator has no water filter; check the owner information if replacing one.
Never assume
- Do not treat water and refrigerator-air filter families as substitutes.
- Do not infer fit for another model, suffix, production revision, or unlisted family code.
- Do not treat product-page part-number variants as interchangeable unless LG confirms that exact part for the exact model.
- Do not infer capacity, certification, contaminant reduction, efficacy, performance, or remaining service life from this fit reference.
Which filter does LG list for LS23C4000V?
LG's captured model lookup lists air filter: LT120F for the complete model LS23C4000V. Match that full label and the category you intend to replace. A water-filter choice and a refrigerator-air filter serve different categories; choose only the category being serviced.
Does a shared filter family prove another model fits?
No. This record establishes the captured family mapping for LS23C4000V. Another refrigerator, suffix or part-number variant needs its own manufacturer evidence. Use the exact model lookup and current product page to resolve a different identifier.
Choose the filter category for this model
- Exact model label: LS23C4000V
- Refrigerator air: use the LG-mapped LT120F family for this model; this is a different category from the water filter.
LG family identifiers and replacement guidance
- LT120F (air): LG lists ADQ73214404, ADQ73334008 on the family product page. These are listed identifiers, not a blanket statement that they are mutually interchangeable for model LS23C4000V. LG lists replacement every six months or when the FILTER alert light turns on.
Check fit and service boundaries
Read the complete model label on the appliance and compare it with the exact string above. Check the existing filter marking and the category being replaced, then open the corresponding LG family page. A locator family result is model-specific evidence; other identifiers printed on that family page are not automatically approved for this model.
LG’s product page gives family-level replacement guidance. Follow the exact refrigerator’s filter indicator and owner information for timing and installation. This reference does not provide a removal/reset sequence, flushing volume, performance specification, or instructions for internal service.
What this result can and cannot decide
- Cabinet-odor question: LG describes LT120F as an air filter that helps remove odor. This page does not establish the cause of an odor; check the owner information and food/storage condition as well. A water filter is not the mapped air-filter choice.
