FGUB2642LP6 specifics — where the filter actually lives

On the FGUB2642LP6, the cartridge in the fresh-food compartment, placement dependent on the dispenser package, the same estate every refrigerator in this family uses. The seat is a twist-in design — align the ears, seat it, and rotate until the stop catches — a five-minute job start to finish.

Two quirks worth knowing before you order: the reset control is the step everyone skips; the light will not acknowledge a new cartridge on its own. One more anchor for the parts search: the ULTRAWF cartridge family is what every fit listing for this chassis resolves to, OEM and certified alternative alike. The P6 tail marks finish variants of one chassis; the filter bay is shared across the entire finish range.

Reading the FGUB2642LP6 model code — what the digits tell you

The 26 cubic feet in the code is the size class; households that size move enough water that the six-month interval is worth honoring. The stable part of the FGUB2642LP6 story is the water path: trim codes shuffle doors and finishes; the ULTRAWF cartridge family is the fixed point.

Swap it in 5 minutes

Installing the replacement water filter in the FGUB2642LP6

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.

What this filter takes out of your water

Old cartridge vs new — the difference a timely swap makes

What it targets	Standard that covers it
Chlorine taste & odor	NSF/ANSI 42 — aesthetic effects
Particulates, Class I	NSF/ANSI 42 — fine sediment
Lead	NSF/ANSI 53 — health effects
Cysts (cryptosporidium, giardia)	NSF/ANSI 53 — microbial
PFOA & PFOS	NSF/ANSI 53 (P473) — varies by cartridge

Coverage above lists what the standard addresses, not a performance claim for any specific cartridge — removal claims vary by certificate, so check the NSF listing for the exact part number you are buying.

FGUB2642LP6 filter questions

Filter light reset on the Frigidaire FGUB2642LP6 — how?

With the new cartridge seated, press and hold the filter reset until the light clears — panel placement differs, so the FGUB2642LP6 manual’s filter section has the exact control for your trim.

Will the Frigidaire FGUB2642LP6 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 FGUB2642LP6?

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.
