Water Filter for the Samsung RF266AAWP (DA29-00003G)

RF266AAWP specifics — where the filter actually lives

The filter bay on the RF266AAWP 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. This is a push-style bay, the simplest geometry there is: the cartridge seats with a click you can feel through the housing; no rotation, no tools, no drama.

Owners of the RF266AAWP report the same friction points: carbon fines in the first pours are normal for a fresh bed, and the filter timer only restarts when you hold the reset. The RF prefix is the tell: 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 WP tail marks finish variants of one chassis; the filter bay is shared across the entire finish range.

RF vs RS — what the prefix tells you

RF versus RS is the first fork in the parts catalog: RF covers French-door multi-door, while RS covers side-by-side. The cartridge line is usually shared across both — order by chassis, not by door count. the 26 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.
