LGUB2642LP8 specifics — where the filter actually lives
On the LGUB2642LP8, the cartridge in the fresh-food compartment — exact spot varies by dispenser layout, so expect to clear one shelf edge before you have working room. It is a twist-lock bay: half a turn of wrist work in each direction is the whole procedure; everything else is towel management.
The recurring owner notes: a first removal that fights a set o-ring, and a status light that needs a manual hold-to-reset before it acknowledges the new cartridge. Under the cabinet differences one thing holds: the ULTRAWF media line; that is the anchor every compatible listing hangs from. The P8 tail marks finish variants of one chassis; the filter bay is shared across the entire finish range.
Reading the LGUB2642LP8 model code — what the digits tell you
Read the code as 26 cubic feet of capacity, which tells you the cartridge’s real workload between changes. One generation, one cartridge: the ULTRAWF cartridge is the one constant across the model run.
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.

LGUB2642LP8 filter questions
How to reset the water filter indicator: Frigidaire LGUB2642LP8?
Hold the filter-reset control a few seconds after the swap; the status light clears only with a seated cartridge, and the LGUB2642LP8 manual maps the control by panel type.
Will the Frigidaire LGUB2642LP8 dispense water without a filter cartridge?
No — the ULTRAWF bay seals on the cartridge itself, so removing it just means unfiltered water until the next change, not a leak.
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 LGUB2642LP8?
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.
