Water Filter for the LG LFD25860SB (LT600P)

LFD25860SB specifics — where the filter actually lives

The filter bay on the LFD25860SB inside the fresh-food cavity, upper zone in most French-door builds, so expect to clear one shelf edge before you have working room. This is a push-twist style bay: seat first, rotate second — reversing the order is the only way to fight this bay, and it will not let you.

Practical notes from the install forums: keep a folded towel under the bay before you open it; the line holds a cup of water even with the valve shut. The LF prefix is the tell: when LG stamps LF on the plate it is sorting the machine into the French-door class — same water path, same cartridge, different cabinet. Trim code SB: cosmetic variants of one chassis, one cartridge family.

LF vs LS — what the prefix tells you

Prefix families here: LF against LS. LF means French-door, LS means side-by-side. For filter shopping the distinction matters less than you would think — same line, different cabinet. capacity 25 cu ft: a mid-to-full-size cabinet whose dispenser traffic sets the realistic change cadence.

Swap it in 5 minutes

• Press the release (if fitted), twist the old cartridge free, and pull it from the header.
• Wet the new cartridge’s o-ring with cold tap water so it seats without dragging.
• Push the cartridge square onto the header, then give it the locking quarter turn.
• Run two gallons through the dispenser to flush carbon fines, then hold the filter-reset control until the status light clears.
