Water Filter for the Frigidaire LFHN2741PP0 (ULTRAWF)

LFHN2741PP0 specifics — where the filter actually lives

The filter bay on the LFHN2741PP0 inside the fresh-food cavity, position varying with dispenser spec, a spot that survives trim changes across the refrigerator run. This is a twist-style bay, the friendlier design: the cartridge drops into the keyed seat and locks with a short quarter turn.

The recurring owner notes: 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. Whatever the badge on the door says, the parts reality is the LFHN2741PP0 shares its water path with the whole ULTRAWF generation — the cartridge is the common denominator, not the door count. The P0 tail marks finish variants of one chassis; the filter bay is shared across the entire finish range.

Reading the LFHN2741PP0 model code — what the digits tell you

The digits in the model number read as cabinet capacity (27 cubic feet), a decent proxy for how hard the filter works in daily service. Fit listings tell the same story: fit charts key on the ULTRAWF cartridge family rather than the door configuration, so trim differences never change the order.

Swap it in 5 minutes

• Twist the old cartridge a quarter turn counterclockwise and pull it straight down — keep a towel in reach for the dribble.
• Fill the new cartridge with cold tap water so the chamber is not fighting an air pocket.
• Offer the new cartridge to the bay, push up, and twist a quarter turn clockwise until the stop catches.
• Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.
