KSSS42FKB00 specifics — where the filter actually lives
The filter bay on the KSSS42FKB00 in the lower fresh-food zone in most side-by-side layouts, knee height or below, the same estate every side-by-side refrigerator in this family uses. The seat is a twist-in design — a quarter turn one way to release, the other to seat, and the only tool you need is a towel for the drip.
Before you click buy, two things: 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. The badge reads KSSS42FKB00, but the chassis reads KSS: in this catalog KSS is the side-by-side marker; internal layouts vary, the bay layout does not. Suffix 00 = production revision; filtration hardware was not part of the revision cycle.
KSS vs the rest of the catalog — what the prefix tells you
Two prefixes, two missions: KSS marks side-by-side builds and the rest of the catalog marks the neighboring layout builds. Cross-checking the prefix before ordering is faster than returning the wrong cartridge. Working from the model code, the KSSS42FKB00 lands somewhere around 2001-2005; treat the window as approximate.
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.

KSSS42FKB00 filter questions
Reset procedure for the change-filter alert on the KSSS42FKB00?
With the new cartridge seated, press and hold the filter reset until the light clears — panel placement differs, so the KSSS42FKB00 manual’s filter section has the exact control for your trim.
Can I run the Kenmore KSSS42FKB00 with no cartridge installed?
You can, but unfiltered — the EDR5RXD1 bay needs no bypass plug; it just passes water through without filtering while the cartridge is out.
Are off-brand filters safe for a Kenmore 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 EDR5RXD1 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 KSSS42FKB00?
Every six months or at the rated gallon capacity, whichever comes first — the EDR5RXD1 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.
