Water Filter for the Samsung RF266ABPN (DA29-00003G)

RF266ABPN specifics — where the filter actually lives

The RF266ABPN carries its water filter top-left of the fresh-food compartment in most French-door layouts, away from the door bins, so expect to clear one shelf edge before you have working room. Mechanically the RF266ABPN uses a push-in cartridge; the alignment is keyed, so it only goes in one way, and hand pressure is all the force required.

Two quirks worth knowing before you order: expect dribble at the bay on removal even with the supply off, and remember the indicator will not self-clear — hold the reset control. Decode the plate and the parts question answers itself: Samsung built these as French-door multi-door machines, and the filter bay inherits the geometry that implies, including where the dispenser feed runs. Finish codes such as PN change the look, not the plumbing — order the cartridge by model, ignore the finish letter.

RF vs RS — what the prefix tells you

RF or RS: the badge difference that does (and does not) change the filter order. French-door multi-door on the RF side, side-by-side on the RS side — the parts catalog runs the same cartridge across both. the 26 cu ft in the code is the size class; households that size move enough water that the six-month interval is worth honoring.

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.
