Water Filter for the Samsung RSH3KTSW (DA29-00003G)

RSH3KTSW specifics — where the filter actually lives

Where the filter actually lives: at the base of the fresh-food compartment in most side-by-side builds — grille or lower rear — usually a kneeling-height or shoulder-height swap, not a teardown. It is a push-lock bay — seat the cartridge square to the header until it clicks, and the retention clips do the rest.

Two quirks worth knowing before you order: a stiff first removal on builds that sat on the same cartridge for years, and an indicator light that wants a manual reset after a non-OEM cartridge is seated. Decode the plate and the parts question answers itself: RS is Samsung’s side-by-side designation proper, and the service literature files every one of these under the same cartridge line. Finish codes such as SW change the look, not the plumbing — order the cartridge by model, ignore the finish letter.

RS vs RF — what the prefix tells you

The catalog pairs RS with RF, and the split matters at order time: side-by-side versus French-door multi-door. Both generations draw from the same cartridge pool, so the prefix is a fit-check, not a barrier. One more anchor for the parts search: the DA2900003G cartridge family is what every fit listing for this chassis resolves to, OEM and certified alternative alike.

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.

What this filter takes out of your water
