Water Filter for the LG LSC27925ST (LT500P)

LSC27925ST specifics — where the filter actually lives

Where the filter actually lives: bottom of the fresh-food column or at the grille line in most side-by-side builds, the same estate every side-by-side refrigerator in this family uses. Mechanically it is a push-and-twist seat: the short locking turn after the press is what keeps the seal honest between changes.

Two quirks worth knowing before you order: the first removal takes more force than every later one, and skipping the reset leaves a change-light glaring at a perfectly fresh cartridge. The LS in LSC27925ST is doing real work: LS machines come from the side-by-side program, and LG’s parts system rewards you for knowing it: one cartridge family covers the run. Finish letter sets like ST never alter the bay; the LT500P line fits the whole set.

LS vs LF — what the prefix tells you

The LS prefix sits next to LF in the catalog and the split is cabinet mission: LS covers side-by-side, while LF covers French-door. The cartridge line is usually shared across both — order by chassis, not by door count. the 27 cu ft in the code is the size class; households that size move enough water that the six-month interval is worth honoring.

Swap it in 5 minutes

• Press the release (if fitted), twist the old cartridge free, and pull it from the header.
• Wet the new cartridge’s o-ring with cold tap water so it seats without dragging.
• Push the cartridge square onto the header, then give it the locking quarter turn.
• Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.
