Water Filter for the Kenmore KBFS20EVBL00 (EDR4RXD1)

KBFS20EVBL00 specifics — where the filter actually lives

The filter bay on the KBFS20EVBL00 upper fresh-food wall in most bottom-freezer builds, the same estate every bottom-freezer refrigerator in this family uses. Mechanically the KBFS20EVBL00 uses a twist-in cartridge: release is counterclockwise, seating is clockwise, and the stops are firm enough that you cannot overshoot.

Before you click buy, two things: the first removal takes more force than every later one, and skipping the reset leaves a change-light glaring at a perfectly fresh cartridge. The badge reads KBFS20EVBL00, but the chassis reads KBF: it usually marks a bottom-freezer layout, which means shared cartridge economics — one media family, dozens of cabinet variants, all drinking from the same parts line. That trailing 00 is the revision counter: KBF chassis revisions share one water path, so the cartridge order never changes with it.

KBF vs KFI — what the prefix tells you

Prefix families here: KBF against KFI. bottom-freezer on the KBF side, French-door on the KFI side — the parts catalog runs the same cartridge across both. Catalog convention puts the KBFS20EVBL00 near 2008-2012 — an approximation, useful for bracketing the cartridge era only.

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.
