LGUB2642LE5 specifics — where the filter actually lives
The LGUB2642LE5 carries its water filter in the fresh-food compartment, placement dependent on the dispenser package, a deliberate placement that keeps the swap away from the door seals and drawer rails. Mechanically it is a quarter-turn twist-in seat: look for the index lugs, offer the cartridge, and rotate until they disappear into the housing.
The recurring owner notes: expect the first swap to take longer than the box suggests — aged o-rings grip — so budget ten minutes, not five. What pins the parts choice down is the media line: this chassis drinks from the ULTRAWF family, one of the most cross-referenced cartridges in the Frigidaire catalog. Trim code E5: cosmetic variants of one chassis, one cartridge family.
Reading the LGUB2642LE5 model code — what the digits tell you
Size class 26 cubic feet — worth knowing because a full household works a cartridge harder than the rated six months assumes. What stays constant across the trim range: the water path is fixed at the ULTRAWF line — that asymmetry is what makes filter shopping simple.
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.

LGUB2642LE5 filter questions
Filter light reset on the Frigidaire LGUB2642LE5 — how?
With the new cartridge seated, press and hold the filter reset until the light clears — panel placement differs, so the LGUB2642LE5 manual’s filter section has the exact control for your trim.
LGUB2642LE5 with no water filter installed — safe, or does it need a bypass?
The bay self-seals: with no cartridge the LGUB2642LE5 still dispenses, just unfiltered. No bypass plug exists for this line.
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 LGUB2642LE5?
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.
