RS2531SW specifics — where the filter actually lives
Where the filter actually lives: behind the lower fresh-food trim or base grille in most side-by-side layouts — usually a kneeling-height or shoulder-height swap, not a teardown. Mechanically it is a push-in bay: the latch does the locking for you; your only job is keeping the cartridge square on the way in.
Practical notes from the install forums: the change light ignores the new cartridge until you reset it, and the first removal always takes more muscle than the manual implies. Decode the plate and the parts question answers itself: when Samsung stamps RS on the plate it is sorting the machine into the side-by-side class — same water path, same cartridge, different cabinet. The SW ending is a finish code — color and handle options, not mechanical ones. Every finish of this chassis takes the same cartridge.
RS vs RF — what the prefix tells you
The catalog pairs RS with RF, and the split matters at order time: side-by-side builds carry RS; French-door multi-door builds carry RF. Filter-wise the two lines converge on one cartridge family. Capacity check: the 25 cu ft in the code is the box size, and bigger boxes push more water through the same cartridge between swaps.
Swap it in 5 minutes
- Pull the old cartridge straight out of the header — expect a small spill, not a flood.
- Align the new cartridge with the keyed slot; it only goes in one orientation.
- Push the cartridge home until the retention latch clicks.
- Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.

RS2531SW filter questions
How do I reset the filter light on the Samsung RS2531SW?
Seat the new cartridge first, then hold the filter-reset control for a few seconds until the status light clears — the exact button placement varies by control panel, so check the RS2531SW owner’s manual page for filter status.
Running the RS2531SW with an empty filter bay — does it need a cap?
The bay self-seals: with no cartridge the RS2531SW still dispenses, just unfiltered. No bypass plug exists for this line.
Are off-brand filters safe for a Samsung 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 DA2900003G 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 RS2531SW?
Every six months or at the rated gallon capacity, whichever comes first — the DA2900003G 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.
