RF34H9950S4/AA-0004 specifics — where the filter actually lives
The filter bay on the RF34H9950S4/AA-0004 high on the fresh-food side in most French-door layouts — upper back or left wall, the same estate every French-door multi-door refrigerator in this family uses. Mechanically the RF34H9950S4/AA-0004 uses a push-in cartridge; no threading, no quarter turn, just a straight push until the latch reports in.
Owners of the RF34H9950S4/AA-0004 report the same friction points: run the first gallon or two through a fresh cartridge before drinking — carbon fines are normal — and reset the indicator so the countdown matches reality. One prefix, one chassis family: RF is Samsung’s own coding for French-door multi-door machines, and in that format the water path is long enough that a neglected cartridge shows up as flow drop before it shows up as taste. Read the 04 ending as a revision marker — Samsung used it for running changes, none of which touched the DA2900020B bay.
RF vs RS — what the prefix tells you
The RF prefix sits next to RS in the catalog and the split is cabinet mission: Chassis first: French-door multi-door (RF) versus side-by-side (RS). The shared cartridge line covers both without adaptation. call it a 34 cubic feet box — which is why this cartridge works for a living rather than sitting decorative.
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.

RF34H9950S4/AA-0004 filter questions
Reset procedure for the change-filter alert on the RF34H9950S4/AA-0004?
The reset is a press-and-hold on the filter control with the cartridge in place; check the RF34H9950S4/AA-0004 owner’s manual for where that control sits on your panel.
Samsung RF34H9950S4/AA-0004: bypass plug needed without a filter?
No — run it empty if you like; the DA2900020B bay needs no bypass plug, it simply passes water through untreated.
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 RF34H9950S4/AA-0004?
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.
