Water Filter for the LG LSC27910SW (LT500P)

LSC27910SW specifics — where the filter actually lives

The LSC27910SW carries its water filter behind the lower fresh-food trim or base grille in most side-by-side layouts — usually a kneeling-height or shoulder-height swap, not a teardown. Mechanically it is a push-and-twist seat: seat first, rotate second — reversing the order is the only way to fight this bay, and it will not let you.

The recurring owner notes: expect the first swap to take longer than the box suggests — aged o-rings grip — so budget ten minutes, not five. Prefix literacy pays here: it places the machine in LG’s side-by-side family, which pins down the cartridge line, the reset behavior, and the service documentation worth consulting. That SW suffix is trim-level shorthand. LG kept the LT500P bay common to every finish in the line.

LS vs LF — what the prefix tells you

The catalog pairs LS with LF, and the split matters at order time: 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 figure in the code is the household size proxy; larger households breach the rated gallons before the calendar does.

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.
