CFD28WIS1 specifics — where the filter actually lives
Where the filter actually lives: in the upper zone of the fresh-food compartment in most bottom-freezer layouts, a spot that survives trim changes across the CFD run. Mechanically it is a quarter-turn twist-in seat: release is counterclockwise, seating is clockwise, and the stops are firm enough that you cannot overshoot.
Practical notes from the install forums: 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. Decode the plate and the parts question answers itself: CFD generally indicates the bottom-freezer family, so cross-referencing cartridges by chassis rather than by door style usually keeps you out of the wrong-parts queue. Trim code S1: cosmetic variants of one chassis, one cartridge family.
CFD vs FFUS — what the prefix tells you
The CFD/FFUS pair divides this family by layout — CFD machines are bottom-freezer; FFUS machines are French-door. Both draw from the same cartridge line, which is why fit charts list them together. call it a 28 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.

CFD28WIS1 filter questions
CFD28WIS1 filter light will not turn off — what is the reset step?
Lock in the new cartridge first, then hold the reset control for a few seconds — the CFD28WIS1 manual documents the button for each panel variant.
Running the CFD28WIS1 with an empty filter bay — does it need a cap?
Nothing to buy — the ULTRAWF housing closes without a cartridge; water runs unfiltered until the next one goes in.
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 CFD28WIS1?
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.
