LG LSC23924ST.ASTCNA0: LT500P filter and verified model matrix
LG product-support pages explicitly list LT500P compatibility for LSC23924ST.ASTCNA0, LSC27925ST.ASTCNA0, LSC27910SW.ASWCLGA, and LFX25974SB.AWBCNA0. LG identifies LT500P and part-number variants ADQ72910911, 5231JA2002A, and ADQ72910901, and gives cartridge-specific installation guidance. A conflict between product-page capacity text is unresolved, so capacity, certification, and contaminant-reduction claims are excluded.
Safety boundary
- Check the exact model manual for water-valve shutoff guidance; protect the floor and check for leaks after installation.
- Do not force an incorrectly aligned cartridge; remove and realign it if it does not seat and lock normally.
- Flush the new cartridge as directed before use; filter replacement is not a test of water safety.
Compatibility requires a direct model listing, explicit supersession, or equivalent manufacturer evidence.

Required identifiers
- Full LG product-support code: LSC23924ST.ASTCNA0, LSC27925ST.ASTCNA0, LSC27910SW.ASWCLGA, or LFX25974SB.AWBCNA0
- Existing cartridge marking LT500P or an exact LG lookup receipt
- Manufacturer part-code variant when selecting a replacement
Compatibility rules
- LG support pages for each of the four complete codes explicitly list compatibility with the LT500P water filter.
- LG identifies LT500P OEM part-number variants ADQ72910911, 5231JA2002A, and ADQ72910901.
- Use only the exact product codes listed here; check the complete label and existing filter marking before ordering.
- The listed fit supports filter-family compatibility only; follow the manual attached to the exact refrigerator code for model-dependent valve and reset details.
Never assume
- LT500P is not a universal LG refrigerator filter; do not transfer fit to an unlisted LSC/LFX model or suffix.
- Do not claim a 200- or 500-gallon capacity, certification, or contaminant reduction from the contradictory product imagery/title.
- Do not assume indicator reset controls are identical across the four refrigerator models.
Exact LG model fit matrix
- LSC23924ST.ASTCNA0 — LG support page lists LT500P compatibility.
- LSC27925ST.ASTCNA0 — LG support page lists LT500P compatibility.
- LSC27910SW.ASWCLGA — LG support page lists LT500P compatibility.
- LFX25974SB.AWBCNA0 — LG support page lists LT500P compatibility.
- LG LT500P part numbers: ADQ72910911 / 5231JA2002A / ADQ72910901.
LT500P replacement steps
- Check the exact model manual for water-supply shutoff; dispense residual line water and protect the area below the filter.
- Remove the cover/shelf as needed; rotate the old LT500P left to unlock, then pull down.
- Remove the new filter's protective packaging, align tabs with the housing slots, push fully in, and turn clockwise to the locked mark.
- Reinstall the cover and shelf, slowly reopen water if shut off, and check for leaks.
- LG's guide describes flushing about 2.5 gallons using 30-second dispensing / 60-second pauses for a total of five minutes; use the exact model manual for indicator reset because settings vary.
Claims intentionally excluded
LG's LT500P page title says 200 gallons while an image-alt label says 500 gallons. Without a current performance sheet, this page does not state capacity, certification scope, or contaminant-reduction performance. Other model suffixes are outside the verified matrix.
