Water Filter for the LG LMXS27626D (LT700P)

LMXS27626D specifics — where the filter actually lives

Finding the bay is the easy part — this chassis puts it in the fresh-food compartment, placement dependent on the dispenser package, a spot that survives trim changes across the LM run. Mechanically it is a push-and-twist seat: seat first, rotate second — reversing the order is the only way to fight this bay, and it will not let you.

The recurring owner notes: the first removal takes more force than every later one, and skipping the reset leaves a change-light glaring at a perfectly fresh cartridge. Read the prefix and the maintenance writes itself: LM is LG’s 4-door Max designation proper, and the service literature files every one of these under the same cartridge line. Trim code 6D: cosmetic variants of one chassis, one cartridge family.

LM vs LF — what the prefix tells you

LM or LF: the badge difference that does (and does not) change the filter order. LM means 4-door Max, LF means French-door. For filter shopping the distinction matters less than you would think — same line, different cabinet. 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.
