CFD26WIS4 specifics — where the filter actually lives
The filter bay on the CFD26WIS4 high on the fresh-food side in most bottom-freezer layouts, above the crispers, the same estate every bottom-freezer refrigerator in this family uses. Mechanically the CFD26WIS4 uses a twist-in cartridge: seat the cartridge against the o-ring, quarter-turn clockwise, and let the keyed flange do the aligning for you.
Before you click buy, two things: keep a folded towel under the bay before you open it; the line holds a cup of water even with the valve shut. The badge reads CFD26WIS4, but the chassis reads CFD: generally a bottom-freezer machine, and the filter bay inherits the geometry that implies — treat as typical, not absolute. The S4 tail marks finish variants of one chassis; the filter bay is shared across the entire finish range.
CFD vs FFUS — what the prefix tells you
The catalog pairs CFD with FFUS, and the split matters at order time: split by cabinet mission (bottom-freezer versus French-door), joined by cartridge line — that is the CFD/FFUS story. The two digits after the letters are the cabinet size: this is a 26 cubic feet refrigerator, which sets how much dispenser work the cartridge does between changes.
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.

CFD26WIS4 filter questions
Reset procedure for the change-filter alert on the CFD26WIS4?
The reset is a press-and-hold on the filter control with the cartridge in place; check the CFD26WIS4 owner’s manual for where that control sits on your panel.
Can I run the Crosley CFD26WIS4 with no cartridge installed?
The bay self-seals: with no cartridge the CFD26WIS4 still dispenses, just unfiltered. No bypass plug exists for this line.
Are off-brand filters safe for a Crosley refrigerator?
Certified aftermarket cartridges are built to the same NSF test standards as the OEM part, and federal warranty law (Magnuson-Moss) protects your coverage when you use them.
Why is the OEM ULTRAWF cartridge so much more expensive?
Part of the OEM price is the badge and the distribution chain. Certified alternatives meet the same test standards at a lower unit price, especially in multi-packs.
How often should I replace the filter in my CFD26WIS4?
Every six months or at the rated gallon capacity, whichever comes first — the ULTRAWF class cartridges all share that service interval.
Do I need to turn off the water supply to change it?
No — the bay is designed for a live swap. Expect a small dribble, keep a towel in reach, and flush a couple of gallons through the new cartridge before the first glass.
