LMX25986SW specifics — where the filter actually lives
The filter bay on the LMX25986SW in the fresh-food compartment — exact spot varies by dispenser layout, a spot that survives trim changes across the LM run. 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.
Two quirks worth knowing before you order: 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. LM is not a trim code, it is a chassis statement: when LG stamps LM on the plate it is sorting the machine into the 4-door Max class — same water path, same cartridge, different cabinet. SW is finish coding: handles, colors, panel options — none of it reaches the filter bay.
LM vs LF — what the prefix tells you
Catalog shorthand: 4-door Max against French-door, respectively. Filter bays rarely care — the media family carries over more often than not. Cabinet decode: 25 cubic feet — the number that tells you whether this cartridge feeds a family-size dispenser or a compact one.
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.

LMX25986SW filter questions
Clearing the filter status light on a LG LMX25986SW?
Press and hold the reset control until the light clears (a few seconds), with the new cartridge already seated — the LMX25986SW owner’s manual lists the button location for your control panel.
LMX25986SW with no water filter installed — safe, or does it need a bypass?
No cap needed — the LT700P bay passes water unfiltered while empty; it does not leak, it just skips filtration.
Are off-brand filters safe for a LG 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 LT700P 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 LMX25986SW?
Every six months or at the rated gallon capacity, whichever comes first — the LT700P 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.
