Water Filter for the LG LRSC26980SB (LT600P)

LRSC26980SB specifics — where the filter actually lives

On the LRSC26980SB, the cartridge in the fresh-food compartment, placement dependent on the dispenser package, a spot that survives trim changes across the refrigerator run. Mechanically the LRSC26980SB uses a push-and-twist cartridge: the cartridge goes in square, then a short rotation locks it against the header — no tools involved.

Owners of the LRSC26980SB report the same friction points: the reset control is the step everyone skips; the light will not acknowledge a new cartridge on its own. Whatever the badge on the door says, the parts reality is the LT600P line — which is why fit listings key on chassis rather than door style. Finish letter sets like SB never alter the bay; the LT600P line fits the whole set.

Reading the LRSC26980SB model code — what the digits tell you

The digits in the model number read as cabinet capacity (26 cu ft), a decent proxy for how hard the filter works in daily service. One generation, one cartridge: the water path is fixed at the LT600P line — that asymmetry is what makes filter shopping simple.

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.
