LG LSXS26326S refrigerator water filter: LT800P
LT800P is a genuine LG refrigerator water filter rated for up to six months or 200 gallons. LG’s model support page links the exact owner manual and filter compatibility item; confirm the complete model code before ordering. LG 26.2-cu.-ft. 36-inch side-by-side refrigerator with an integrated tall ice/water dispenser and SpacePlus ice system. This record stays within the exact model string and cartridge source listed by the manufacturer; it is not a broad brand-family compatibility claim.
Safety boundary
- Use the exact model owner’s manual before replacement. LG says some models allow replacement without closing the water valve and others may require it; follow the exact manual.
- Place a towel or cup below the filter for drips. Use the model’s LT800P instructions and do not force a misaligned cartridge.
- LG’s general LT800P guide says to dispense about 2.5 gallons after a new filter and then reset the indicator, but controls/method vary by model; follow the exact model manual if different.
- Stop and check for leaks before returning to normal dispensing. Do not use water filters as disinfection.
Compatibility requires a direct model listing, explicit supersession, or equivalent manufacturer evidence.
Models explicitly covered
These model identities have the source evidence listed below. Read the part decision and suffix limits before ordering.
Required identifiers
- Exact refrigerator model from rating plate: LSXS26326S.
- Full product/SKU code where applicable: LSXS26326S.ASTCNA0.

Compatibility rules

Never assume

- The general LT800P instructions necessarily match the exact filter location/reset controls of this model; use the model owner manual.
- A certified reduction claim means the filter disinfects microbiologically unsafe water or makes unknown-quality water safe.
