Water Filter for the LG LFX29927SW (LT700P)

LFX29927SW specifics — where the filter actually lives

Finding the bay is the easy part — this chassis puts it upper rear of the fresh-food section in most French-door builds with interior dispensers, the same estate every French-door refrigerator in this family uses. The seat combines push-fit and twist-lock: the cartridge goes in square, then a short rotation locks it against the header — no tools involved.

The small print owners learn the hard way: 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. LF is not a trim code, it is a chassis statement: LG built these as French-door machines, and the filter bay inherits the geometry that implies, including where the dispenser feed runs. Finish letter sets like SW never alter the bay; the LT700P line fits the whole set.

LF vs LS — what the prefix tells you

The LF prefix sits next to LS in the catalog and the split is cabinet mission: French-door against side-by-side, respectively. Filter bays rarely care — the media family carries over more often than not. capacity 29 cu ft: 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.
