Water Filter for the LG LPXS30866D (LT800P)

LPXS30866D specifics — where the filter actually lives

Where the filter actually lives: in the fresh-food compartment, placement dependent on the dispenser package, the same estate every 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.

Two quirks worth knowing before you order: the line is still live when you open the bay, so keep a towel in reach, and expect the filter-status light to need a reset before it believes the new cartridge. Under the cabinet differences one thing holds: the LT800P line — which is why fit listings key on chassis rather than door style. Finish letter sets like 6D never alter the bay; the LT800P line fits the whole set.

Reading the LPXS30866D model code — what the digits tell you

Read the code as 30 cubic feet of capacity, which tells you the cartridge’s real workload between changes. The parts catalog sees it simply: every variant of this chassis locks onto the LT800P line — that is the whole parts story.

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.
