LSC23924SB specifics — where the filter actually lives
The filter bay on the LSC23924SB bottom of the fresh-food column or at the grille line in most side-by-side builds, a spot that survives trim changes across the LS run. The seat combines push-fit and twist-lock: seat first, rotate second — reversing the order is the only way to fight this bay, and it will not let you.
Field notes: the line is still live when you open the bay, so keep a towel in reach, and expect the filter-status light to need a reset before it believes the new cartridge. One prefix, one chassis family: LG built these as side-by-side machines, and the filter bay inherits the geometry that implies, including where the dispenser feed runs. SB is finish coding: handles, colors, panel options — none of it reaches the filter bay.
LS vs LF — what the prefix tells you
Catalog shorthand: Ordering by prefix works because LS means side-by-side and LF means French-door in this catalog — and the cartridge pool overlaps both. cabinet class 23 cubic feet — a box that size leans on the dispenser, so the six-month cartridge interval earns its keep.
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.

LSC23924SB filter questions
Reset procedure for the change-filter alert on the LSC23924SB?
Lock in the new cartridge first, then hold the reset control for a few seconds — the LSC23924SB manual documents the button for each panel variant.
LG LSC23924SB: bypass plug needed without a filter?
No cap needed — the LT500P bay passes water unfiltered while empty; it does not leak, it just skips filtration.
Are off-brand filters safe for a LG refrigerator?
Certified aftermarket cartridges are built to the same NSF test standards as the OEM part, and federal warranty law (Magnuson-Moss) protects your coverage when you use them.
Why is the OEM LT500P cartridge so much more expensive?
Part of the OEM price is the badge and the distribution chain. Certified alternatives meet the same test standards at a lower unit price, especially in multi-packs.
How often should I replace the filter in my LSC23924SB?
Every six months or at the rated gallon capacity, whichever comes first — the LT500P class cartridges all share that service interval.
Do I need to turn off the water supply to change it?
No — the bay is designed for a live swap. Expect a small dribble, keep a towel in reach, and flush a couple of gallons through the new cartridge before the first glass.
