RF30KMEDBSR/AA-03 specifics — where the filter actually lives
Finding the bay is the easy part — this chassis puts it top-left of the fresh-food compartment in most French-door layouts, away from the door bins — usually a kneeling-height or shoulder-height swap, not a teardown. It is a push-lock bay — the cartridge seats with a click you can feel through the housing; no rotation, no tools, no drama.
The recurring owner notes: plan on a towel for the first pull — sitting water in the line — and a five-second reset hold once the fresh cartridge is in. The RF in RF30KMEDBSR/AA-03 is doing real work: it places the machine in Samsung’s French-door multi-door family, which pins down the cartridge line, the reset behavior, and the service documentation worth consulting. The -03 tail tracks the revision ladder — each rung shares the identical DA2900020B bay.
RF vs RS — what the prefix tells you
Prefix families here: RF against RS. split by cabinet mission (French-door multi-door versus side-by-side), joined by cartridge line — that is the RF/RS story. cabinet class 30 cubic feet — a box that size leans on the dispenser, so the six-month cartridge interval earns its keep.
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.

RF30KMEDBSR/AA-03 filter questions
Filter light reset on the Samsung RF30KMEDBSR/AA-03 — how?
The reset is a press-and-hold on the filter control with the cartridge in place; check the RF30KMEDBSR/AA-03 owner’s manual for where that control sits on your panel.
Does the Samsung RF30KMEDBSR/AA-03 need a bypass plug when the filter is out?
No — the DA2900020B bay seals on the cartridge itself, so removing it just means unfiltered water until the next change, not a leak.
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 RF30KMEDBSR/AA-03?
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.
