LGHS2644KM2 specifics — where the filter actually lives
The filter bay on the LGHS2644KM2 in the fresh-food compartment — exact spot varies by dispenser layout, the same estate every refrigerator in this family uses. It is a twist-lock bay: the ears on the cartridge neck are the guide — line them up, lift into the seat, and quarter-turn home.
Field notes: a stiff first removal on builds that sat on the same cartridge for years, and an indicator light that wants a manual reset after a non-OEM cartridge is seated. Whatever the badge on the door says, the parts reality is the ULTRAWF line — which is why fit listings key on chassis rather than door style. Trim code M2: cosmetic variants of one chassis, one cartridge family.
Reading the LGHS2644KM2 model code — what the digits tell you
26 cu ft of cabinet — the dispenser sees heavy traffic at that size, and heavy traffic ages cartridges faster. The parts catalog sees it simply: the same ULTRAWF family covers this chassis end to end.
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.

LGHS2644KM2 filter questions
Clearing the filter status light on a Frigidaire LGHS2644KM2?
Seat the new cartridge first, then hold the filter-reset control for a few seconds until the status light clears — the exact button placement varies by control panel, so check the LGHS2644KM2 owner’s manual page for filter status.
Frigidaire LGHS2644KM2: bypass plug needed without a filter?
You can, but unfiltered — the ULTRAWF bay needs no bypass plug; it just passes water through without filtering while the cartridge is out.
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 LGHS2644KM2?
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.
