Water Filter for the LG LFXS29626S-01 (LT700P)

LFXS29626S/01 specifics — where the filter actually lives

The LFXS29626S/01 carries its water filter in the fresh-food compartment, typically the upper back wall in most French-door layouts, so expect to clear one shelf edge before you have working room. It is a push-twist bay — seat first, rotate second — reversing the order is the only way to fight this bay, and it will not let you.

Order-day practicalities: 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. The badge reads LFXS29626S/01, but the chassis reads LF: it places the machine in LG’s French-door family, which pins down the cartridge line, the reset behavior, and the service documentation worth consulting. Suffix 01 = production revision; filtration hardware was not part of the revision cycle.

LF vs LS — what the prefix tells you

Know your LF from your LS and the cartridge question halves: The French-door/side-by-side split tracks the LF/LS prefixes — cartridge fit follows the water path, not the label on the door. the 29 cu ft in the code is the size class; households that size move enough water that the six-month interval is worth honoring.

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.
