LFD25860SW specifics — where the filter actually lives
The filter bay on the LFD25860SW upper rear of the fresh-food section in most French-door builds with interior dispensers, a deliberate placement that keeps the swap away from the door seals and drawer rails. This is a push-twist style bay: the short locking turn after the press is what keeps the seal honest between changes.
Two quirks worth knowing before you order: 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. Prefix literacy pays here: when LG stamps LF on the plate it is sorting the machine into the French-door class — same water path, same cartridge, different cabinet. Finish codes such as SW change the look, not the plumbing — order the cartridge by model, ignore the finish letter.
LF vs LS — what the prefix tells you
LF or LS: the badge difference that does (and does not) change the filter order. Ordering by prefix works because LF means French-door and LS means side-by-side in this catalog — and the cartridge pool overlaps both. cabinet class 25 cu ft — a box that size leans on the dispenser, so the six-month cartridge interval earns its keep.
Swap it in 5 minutes
- Press the release (if fitted), twist the old cartridge free, and pull it from the header.
- Wet the new cartridge’s o-ring with cold tap water so it seats without dragging.
- Push the cartridge square onto the header, then give it the locking quarter turn.
- Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.

LFD25860SW filter questions
LFD25860SW filter light will not turn off — what is the reset step?
With the new cartridge seated, press and hold the filter reset until the light clears — panel placement differs, so the LFD25860SW manual’s filter section has the exact control for your trim.
Does the LG LFD25860SW need a bypass plug when the filter is out?
No cap needed — the LT600P bay passes water unfiltered while empty; it does not leak, it just skips filtration.
Are off-brand filters safe for a LG 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 LT600P 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 LFD25860SW?
Every six months or at the rated gallon capacity, whichever comes first — the LT600P 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.
