LSXS26386S specifics — where the filter actually lives
On the LSXS26386S, the cartridge low on the fresh-food side or behind the base grille in most side-by-side layouts, a spot that survives trim changes across the LS run. The seat combines push-fit and twist-lock: press, quarter-turn, finished — the two-step seat keeps the o-ring from dragging on installation.
Before you click buy, two things: expect dribble at the bay on removal even with the supply off, and remember the indicator will not self-clear — hold the reset control. Read the prefix and the maintenance writes itself: LG built these as side-by-side machines, and the filter bay inherits the geometry that implies, including where the dispenser feed runs. That 6S suffix is trim-level shorthand. LG kept the LT800P 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 answers to side-by-side; LF answers to French-door; the water-filter answer is shared. capacity 26 cubic feet: 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.

LSXS26386S filter questions
Clearing the filter status light on a LG LSXS26386S?
Lock in the new cartridge first, then hold the reset control for a few seconds — the LSXS26386S manual documents the button for each panel variant.
Does the LG LSXS26386S need a bypass plug when the filter is out?
No — run it empty if you like; the LT800P bay needs no bypass plug, it simply passes water through untreated.
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 LT800P 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 LSXS26386S?
Every six months or at the rated gallon capacity, whichever comes first — the LT800P 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.
