Water Filter for the Frigidaire FGHS2667KB4 (ULTRAWF)

FGHS2667KB4 specifics — where the filter actually lives

Finding the bay is the easy part — this chassis puts it in the fresh-food compartment, typically the upper back wall in most French-door layouts, a spot that survives trim changes across the FGHS run. It is a twist-lock bay: a quarter turn one way to release, the other to seat, and the only tool you need is a towel for the drip.

Field 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. One prefix, one chassis family: it usually places the machine in the French-door family, a strong hint at the cartridge line, the reset behavior, and the service documentation worth consulting. That B4 suffix is trim-level shorthand. Frigidaire kept the ULTRAWF bay common to every finish in the line.

FGHS vs FFHS — what the prefix tells you

FGHS versus FFHS is the first fork in the parts catalog: FGHS marks French-door builds and FFHS marks side-by-side builds. Cross-checking the prefix before ordering is faster than returning the wrong cartridge. capacity 26 cu ft: a mid-to-full-size cabinet whose dispenser traffic sets the realistic change cadence.

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.
