LRSC26905 specifics — where the filter actually lives
The filter bay on the LRSC26905 in the fresh-food compartment, placement dependent on the dispenser package, a spot that survives trim changes across the refrigerator run. The seat combines push-fit and twist-lock: the cartridge locks with a short rotation after seating; if it rotates freely, it is not seated.
Order-day practicalities: a stiff first removal on builds that sat on the same cartridge for years, and an indicator light that wants a manual reset after a non-OEM cartridge is seated. What pins the parts choice down is the media line: the LRSC26905 shares its water path with the whole LT500P generation — the cartridge is the common denominator, not the door count. Read the 05 ending as a revision marker — LG used it for running changes, none of which touched the LT500P bay.
Reading the LRSC26905 model code — what the digits tell you
Capacity check: the 26 cu ft in the code is the box size, and bigger boxes push more water through the same cartridge between swaps. Order by cartridge, not by cabinet: whatever the door count, the cartridge answer for this chassis is the LT500P family.
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.

LRSC26905 filter questions
LRSC26905 filter light will not turn off — what is the reset step?
Seat the new cartridge first, then hold the filter-reset control for a few seconds until the status light clears — the exact button placement varies by control panel, so check the LRSC26905 owner’s manual page for filter status.
LG LRSC26905: 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 LRSC26905?
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.
