Water Filter for the Frigidaire PLHS239ZCB1

PLHS239ZCB1 specifics — where the filter actually lives

On the PLHS239ZCB1, the cartridge bottom of the fresh-food column or at the grille line in most side-by-side builds, a spot that survives trim changes across the PLHS run. Mechanically the PLHS239ZCB1 uses a twist-in cartridge: a quarter turn one way to release, the other to seat, and the only tool you need is a towel for the drip.

Two quirks worth knowing before you order: run the first gallon or two through a fresh cartridge before drinking — carbon fines are normal — and reset the indicator so the countdown matches reality. The PLHS in PLHS239ZCB1 is doing real work: PLHS generally indicates the side-by-side family, so cross-referencing cartridges by chassis rather than by door style usually keeps you out of the wrong-parts queue. The B1 ending is a finish code — color and handle options, not mechanical ones. Every finish of this chassis takes the same cartridge.

PLHS vs FFSS — what the prefix tells you

PLHS and FFSS are neighbors in the same side-by-side family; the catalog uses them for different production runs, the parts system does not. call it a 23 cubic feet box — which is why this cartridge works for a living rather than sitting decorative.

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.
