LSC27937SB specifics — where the filter actually lives
Where the filter actually lives: in the lower fresh-food zone in most side-by-side layouts, knee height or below, the same estate every side-by-side refrigerator in this family uses. Mechanically it is a push-and-twist seat: the cartridge locks with a short rotation after seating; if it rotates freely, it is not seated.
Practical notes from the install forums: flush before the first glass — new carbon beds shed fines for the first gallon or so, which is cosmetic, not contamination. LS is not a trim code, it is a chassis statement: it places the machine in LG’s side-by-side family, which pins down the cartridge line, the reset behavior, and the service documentation worth consulting. SB is finish coding: handles, colors, panel options — none of it reaches the filter bay.
LS vs LF — what the prefix tells you
The LS/LF pair divides this family by layout — Ordering by prefix works because LS means side-by-side and LF means French-door in this catalog — and the cartridge pool overlaps both. capacity 27 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.

LSC27937SB filter questions
Clearing the filter status light on a LG LSC27937SB?
Lock in the new cartridge first, then hold the reset control for a few seconds — the LSC27937SB manual documents the button for each panel variant.
LSC27937SB with no water filter installed — safe, or does it need a bypass?
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 LSC27937SB?
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.
