LGHS2644KM1 specifics — where the filter actually lives
The filter bay on the LGHS2644KM1 inside the fresh-food cavity, position varying with dispenser spec, the same estate every refrigerator in this family uses. Mechanically it is a quarter-turn twist-in seat: a quarter turn one way to release, the other to seat, and the only tool you need is a towel for the drip.
Owners of the LGHS2644KM1 report the same friction points: a stubborn first twist when the old o-ring has set, and a change-filter light that will not clear itself until you hold the reset. Under the cabinet differences one thing holds: the ULTRAWF line — which is why fit listings key on chassis rather than door style. The M1 tail marks finish variants of one chassis; the filter bay is shared across the entire finish range.
Reading the LGHS2644KM1 model code — what the digits tell you
The 26 cubic feet figure in the code is the household size proxy; larger households breach the rated gallons before the calendar does. The parts catalog sees it simply: every variant of this chassis locks onto the ULTRAWF line — that is the whole parts story.
Swap it in 5 minutes
- Twist the old cartridge a quarter turn counterclockwise and pull it straight down — keep a towel in reach for the dribble.
- Fill the new cartridge with cold tap water so the chamber is not fighting an air pocket.
- Offer the new cartridge to the bay, push up, and twist a quarter turn clockwise until the stop catches.
- Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.

LGHS2644KM1 filter questions
Clearing the filter status light on a Frigidaire LGHS2644KM1?
With the new cartridge seated, press and hold the filter reset until the light clears — panel placement differs, so the LGHS2644KM1 manual’s filter section has the exact control for your trim.
Will the Frigidaire LGHS2644KM1 dispense water without a filter cartridge?
No — run it empty if you like; the ULTRAWF bay needs no bypass plug, it simply passes water through untreated.
Are off-brand filters safe for a Frigidaire 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 ULTRAWF 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 LGHS2644KM1?
Every six months or at the rated gallon capacity, whichever comes first — the ULTRAWF 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.
