RF28K9380SG specifics — where the filter actually lives

The filter bay on the RF28K9380SG 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. The seat is a push-fit design: remove and replace are mirror images — straight out, straight in, click, done.

Before you click buy, two things: the line is still live when you open the bay, so keep a towel in reach, and expect the filter-status light to need a reset before it believes the new cartridge. Decode the plate and the parts question answers itself: the RF run is Samsung’s French-door multi-door series; across the run, the filter bay is one of the constants. Finish codes such as SG change the look, not the plumbing — order the cartridge by model, ignore the finish letter.

RF vs RS — what the prefix tells you

Same parts shelf, two cabinet missions — Chassis first: French-door multi-door (RF) versus side-by-side (RS). The shared cartridge line covers both without adaptation. The digits in the model number read as cabinet capacity (28 cu ft), a decent proxy for how hard the filter works in daily service.

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.

RF28K9380SG filter questions

How do I reset the filter light on the Samsung RF28K9380SG?

Lock in the new cartridge first, then hold the reset control for a few seconds — the RF28K9380SG manual documents the button for each panel variant.

Is a bypass plug required for the RF28K9380SG when the cartridge is removed?

Nothing to buy — the DA2900020B housing closes without a cartridge; water runs unfiltered until the next one goes in.

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 RF28K9380SG?

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.
