Water Filter for the LG LRSC26941SB (LT600P)

LRSC26941SB specifics — where the filter actually lives

The LRSC26941SB carries its water filter in the fresh-food compartment, placement dependent on the dispenser package, a spot that survives trim changes across the refrigerator run. Mechanically it is a push-and-twist seat: a push to register, a turn to lock; the sequence is printed on most cartridges for a reason.

Two quirks worth knowing before you order: the first removal takes more force than every later one, and skipping the reset leaves a change-light glaring at a perfectly fresh cartridge. Under the cabinet differences one thing holds: the LT600P media line; that is the anchor every compatible listing hangs from. The SB ending is a finish code — color and handle options, not mechanical ones. Every finish of this chassis takes the same cartridge.

Reading the LRSC26941SB model code — what the digits tell you

Capacity check: the 26 cu ft in the code is the box size, and bigger boxes push more water through the same cartridge between swaps. Cross-checking by chassis pays off here: whatever the door count, the cartridge answer for this chassis is the LT600P family.

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.
