LSC27910ST specifics — where the filter actually lives

The LSC27910ST carries its water filter 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. It is a push-twist bay — the cartridge goes in square, then a short rotation locks it against the header — no tools involved.

Order-day practicalities: keep a folded towel under the bay before you open it; the line holds a cup of water even with the valve shut. One prefix, one chassis family: LS is LG’s side-by-side designation proper, and the service literature files every one of these under the same cartridge line. Trailing letters like ST denote trim and finish: stainless, panel-ready, handle variants. The water path is identical across them.

LS vs LF — what the prefix tells you

The LS/LF pair divides this family by layout — LS means side-by-side, LF means French-door. For filter shopping the distinction matters less than you would think — same line, different cabinet. The digits in the model number read as cabinet capacity (27 cubic feet), a decent proxy for how hard the filter works in daily service.

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.

LSC27910ST filter questions

LG LSC27910ST: how do I clear the change-filter light?

Press and hold the reset control until the light clears (a few seconds), with the new cartridge already seated — the LSC27910ST owner’s manual lists the button location for your control panel.

LG LSC27910ST: bypass plug needed without a filter?

No bypass needed: the LT500P bay closes on its own, and running empty simply means the water skips filtration until you seat a new cartridge.

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 LSC27910ST?

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.
