Water Filter for the LG LSC26905SB (LT500P)

LSC26905SB specifics — where the filter actually lives

On the LSC26905SB, the cartridge low on the fresh-food side or behind the base grille in most side-by-side layouts, a deliberate placement that keeps the swap away from the door seals and drawer rails. Mechanically it is a push-and-twist seat: seat the cartridge, give it the quarter turn, and the bay takes it from there.

Two quirks worth knowing before you order: expect the first swap to take longer than the box suggests — aged o-rings grip — so budget ten minutes, not five. One prefix, one chassis family: when LG stamps LS on the plate it is sorting the machine into the side-by-side class — same water path, same cartridge, different cabinet. Finish letter sets like SB never alter the bay; the LT500P line fits the whole set.

LS vs LF — what the prefix tells you

Two prefixes, two missions: LS marks side-by-side builds and LF marks French-door builds. Cross-checking the prefix before ordering is faster than returning the wrong cartridge. capacity 26 cu ft: a mid-to-full-size cabinet whose dispenser traffic sets the realistic change cadence.

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.
