LG LT600P Refrigerator Water Filter — 5231JA2006A, 5231JA2006B & Kenmore 46-9990

Quick check — is this your filter? Pull the filter currently in your refrigerator and read the label. If it says LT600P, 5231JA2006A, 5231JA2006B, 5231JA2006F, or Kenmore 46-9990 / 9990, this is the correct replacement. If it says LT500P, LT700P, LT800P or LT1000P, you need a different filter — see the LG filter guide below.

Product Description

The LG LT600P is the twist-in replacement water filter fitted to a large range of LG side-by-side, French door and bottom-freezer refrigerators built with the internal LT600P housing, plus the Kenmore models built on the same platform. It is the filter behind part numbers 5231JA2006A, 5231JA2006B and 5231JA2006F, and Kenmore filter number 46-9990.

Inside the cartridge, a compressed activated carbon block reduces chlorine taste and odour so the water and ice coming out of your dispenser taste clean rather than of tap water, while the outer filtration layer traps sediment, rust particles and other grit picked up in household plumbing. The result is clearer water, better-tasting ice, and less sediment finding its way into the dispenser line.

Each cartridge is rated for approximately 300 gallons or 6 months of normal household use, whichever comes first. It fits with a simple quarter-turn twist — no tools, no water shut-off, and no dismantling of the fridge interior. Most LG refrigerators will show a filter status light on the dispenser panel when the cartridge is due for replacement.

Because filters are replaced on a fixed schedule rather than when they fail, most customers buy more than one at a time. Use the pack size selector above to order a single cartridge or a multi-pack that covers you for the next one to two years.

Key Features

Which LG Filter Do I Need?

LG uses five main refrigerator filter cartridges and they are physically different from each other — an LT700P will not fit an LT600P housing and vice versa. Match your existing part number to the table below before ordering.

LG Filter Common Part Numbers Kenmore Number
LT500P 5231JA2002A 46-9890
LT600P (this filter) 5231JA2006A, 5231JA2006B, 5231JA2006F 46-9990
LT700P ADQ36006101, ADQ36006102 46-9690
LT800P ADQ73613401 46-9490
LT1000P ADQ74793501, MDJ64844601 46-9980

Compatible Refrigerator Models

The LT600P fits LG refrigerators across the LFD, LFX, LMX, LRBC, LRFD, LSC and LRSC series, along with Kenmore refrigerators using filter number 46-9990.

Finding your model number: Open the fresh food compartment and look for a label on the interior side wall, usually near the top on the left or right. The refrigerator model number will begin with the series letters shown below. If you cannot find it, checking the part number on your current filter is the faster and more reliable method.

Kenmore Refrigerators

Kenmore refrigerators built on the LG platform use this cartridge under Kenmore filter numbers 46-9990, 9990 and 469990. Kenmore prints the filter number on the cartridge itself and on the inside of the fresh food door — check that number rather than the refrigerator model number.

Installation Instructions

  1. Locate the filter: The cartridge sits inside the fresh food compartment — on most LT600P refrigerators it is in the upper right corner near the ceiling, or at the base of the compartment on some bottom-freezer models
  2. Remove the old filter: Turn the old cartridge counter-clockwise about a quarter turn and pull it straight out. A small amount of water will drip from the housing, so have a cloth ready
  3. Prepare the new filter: Take the protective cap off the new cartridge and check the O-rings are seated and undamaged
  4. Fit the new filter: Push the cartridge into the housing and turn it clockwise about a quarter turn until it stops and sits flush
  5. Flush the system: Dispense roughly 2 gallons of water, or run the dispenser for about 5 minutes, to clear trapped air and carbon fines. Cloudy or sputtering water during this stage is normal and clears on its own
  6. Discard the first ice: Throw away the first two or three batches of ice so the ice maker is running on fully flushed water
  7. Reset the indicator: Press and hold the filter reset button on the dispenser panel until the light changes colour or turns off. The button label varies by model — check your owner's manual if it is not marked
Installation tip: A quarter turn is all it takes. If the cartridge resists, do not force it — pull it back out, check the alignment tabs, and re-insert. A correctly seated filter sits flush against the housing with no wobble and no drip.

Replacement Schedule

Condition What To Do
Every 6 months Replace the cartridge as routine maintenance, even if the water still tastes fine
After about 300 gallons Replace the cartridge — whichever comes first, 6 months or 300 gallons
Filter light turns red or amber Your refrigerator is telling you the cartridge is at the end of its rated life
Dispenser flow slows down Replace now — a restricted cartridge makes the dispenser slow and the ice maker underfill
Taste or odour returns Replace now — the carbon has reached capacity

Frequently Asked Questions

How do I know the LT600P is the right filter for my refrigerator?

Read the label on the cartridge currently installed in your fridge. If it shows LT600P, 5231JA2006A, 5231JA2006B, 5231JA2006F or Kenmore 46-9990, this is the correct replacement. LG's five filter cartridges are physically different sizes and shapes, so a filter from another series will not seat in an LT600P housing.

Are LT600P, LT600P-B and LT600PC the same filter?

Yes. The suffixes refer to packaging and cosmetic variations, not to different cartridges. All three fit the same housing and are fully interchangeable.

Will this fit my Kenmore refrigerator?

If your Kenmore uses filter number 46-9990, 9990 or 469990, yes. Kenmore refrigerators built on the LG platform share this cartridge. Check the number printed on your current filter to confirm.

Where is the filter located inside the refrigerator?

On most LT600P-equipped models it is inside the fresh food compartment in the upper right corner, near the ceiling. On some bottom-freezer models it sits at the base of the fresh food compartment instead. It is always inside the refrigerator, never in the freezer or behind the base grille.

Do I need to turn off the water supply first?

No. The housing seals itself when the cartridge is removed. Expect a small amount of water to drip out as you pull the old filter, so keep a cloth underneath.

Why is my water cloudy or sputtering after fitting a new filter?

That is trapped air in the line and a small amount of harmless carbon dust, and it is expected on every filter change. Dispensing about 2 gallons clears it. If the water is still cloudy after that, dispense another gallon before assuming anything is wrong.

How many should I buy?

The cartridge is replaced on a schedule rather than on failure, so a multi-pack covers you for the next one to two years and saves reordering every six months. Choose your pack size from the selector above.
