LFX28968ST specifics — where the filter actually lives
Where the filter actually lives: high on the fresh-food side in most French-door layouts — upper back or left wall, the same estate every French-door refrigerator in this family uses. It is a push-twist bay — offer the cartridge to the header, press, and rotate until the stop catches; a towel handles the dribble.
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. One prefix, one chassis family: LG uses it across the French-door range, which means shared cartridge economics — one media family, dozens of cabinet variants, all drinking from the same parts catalog. ST is finish coding: handles, colors, panel options — none of it reaches the filter bay.
LF vs LS — what the prefix tells you
LF or LS: the badge difference that does (and does not) change the filter order. LF answers to French-door; LS answers to side-by-side; the water-filter answer is shared. call it a 28 cubic feet box — which is why this cartridge works for a living rather than sitting decorative.
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.

LFX28968ST filter questions
Clearing the filter status light on a LG LFX28968ST?
The reset is a press-and-hold on the filter control with the cartridge in place; check the LFX28968ST owner’s manual for where that control sits on your panel.
Does the LG LFX28968ST need a bypass plug when the filter is out?
Nothing to buy — the LT700P housing closes without a cartridge; water runs unfiltered until the next one goes in.
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 LT700P 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 LFX28968ST?
Every six months or at the rated gallon capacity, whichever comes first — the LT700P 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.
