Water Filter for the LG LSC27937ST (LT600P)

LSC27937ST specifics — where the filter actually lives

The LSC27937ST carries its water filter in the lower fresh-food zone in most side-by-side layouts, knee height or below — usually a kneeling-height or shoulder-height swap, not a teardown. Mechanically it is a push-and-twist seat: two motions, one orientation, five minutes including the cleanup.

Practical notes from the install forums: keep a folded towel under the bay before you open it; the line holds a cup of water even with the valve shut. Prefix literacy pays here: LS is LG’s own coding for side-by-side machines, and in that format the water path is long enough that a neglected cartridge shows up as flow drop before it shows up as taste. That ST suffix is trim-level shorthand. LG kept the LT600P bay common to every finish in the line.

LS vs LF — what the prefix tells you

The LS prefix sits next to LF in the catalog and the split is cabinet mission: Chassis first: side-by-side (LS) versus French-door (LF). The shared cartridge line covers both without adaptation. Capacity check: the 27 cu ft in the code is the box size, and bigger boxes push more water through the same cartridge between swaps.

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.
