RF31FMEDBSR specifics — where the filter actually lives
Where the filter actually lives: in the fresh-food compartment, typically the upper back wall in most French-door layouts, so expect to clear one shelf edge before you have working room. The seat is a push-fit design: pull the old cartridge straight out, push the new one home until it latches, and you are done.
The recurring owner notes: the first removal takes more force than every later one, and skipping the reset leaves a change-light glaring at a perfectly fresh cartridge. One prefix, one chassis family: RF marks the French-door multi-door line in Samsung’s catalog, so cross-referencing cartridges by chassis rather than by door style keeps you out of the wrong-parts queue. That SR suffix is trim-level shorthand. Samsung kept the DA2900020B bay common to every finish in the line.
RF vs RS — what the prefix tells you
The catalog pairs RF with RS, and the split matters at order time: RF marks French-door multi-door builds and RS marks side-by-side builds. Cross-checking the prefix before ordering is faster than returning the wrong cartridge. the 31 cubic feet figure in the code is the household size proxy; larger households breach the rated gallons before the calendar does.
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.

RF31FMEDBSR filter questions
Filter light reset on the Samsung RF31FMEDBSR — how?
With the new cartridge seated, press and hold the filter reset until the light clears — panel placement differs, so the RF31FMEDBSR manual’s filter section has the exact control for your trim.
Samsung RF31FMEDBSR: bypass plug needed without a filter?
You can, but unfiltered — the DA2900020B bay needs no bypass plug; it just passes water through without filtering while the cartridge is out.
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 DA2900020B 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 RF31FMEDBSR?
Every six months or at the rated gallon capacity, whichever comes first — the DA2900020B 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.
