LRSC26940ST specifics — where the filter actually lives
On the LRSC26940ST, the cartridge in the fresh-food compartment — exact spot varies by dispenser layout, so expect to clear one shelf edge before you have working room. It is a push-twist bay — seat the cartridge, give it the quarter turn, and the bay takes it from there.
Practical notes from the install forums: a stubborn first twist when the old o-ring has set, and a change-filter light that will not clear itself until you hold the reset. The constant across every trim of this machine is the cartridge line — this chassis drinks from the LT600P family, one of the most cross-referenced cartridges in the LG catalog. ST is finish coding: handles, colors, panel options — none of it reaches the filter bay.
Reading the LRSC26940ST model code — what the digits tell you
Cabinet class 26 cu ft — a box that size leans on the dispenser, so the six-month cartridge interval earns its keep. Cross-checking by chassis pays off here: the LT600P cartridge is the one constant across the model run.
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.

LRSC26940ST filter questions
LG LRSC26940ST: how do I clear the change-filter light?
Lock in the new cartridge first, then hold the reset control for a few seconds — the LRSC26940ST manual documents the button for each panel variant.
Does the LG LRSC26940ST need a bypass plug when the filter is out?
No cap needed — the LT600P 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 LT600P 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 LRSC26940ST?
Every six months or at the rated gallon capacity, whichever comes first — the LT600P 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.
