LG LT500P Refrigerator Water Filter (5231JA2002A / ADQ72910901)

Product Description

The LG LT500P is LG's compact replacement water filter for select side-by-side and bottom-freezer refrigerators. Certified by NSF International, this filter delivers clean, fresh-tasting water and ice directly from your refrigerator dispenser by reducing chlorine taste, odor, sediment, and other common contaminants found in tap water.

The LT500P is one of LG's most compact filter designs, making it ideal for refrigerators where internal space is a consideration. It installs with a simple twist — no tools required — and should be replaced every 6 months to maintain optimal performance.

Kenmore Compatible Models

Compatibility Tip: If your LG refrigerator model begins with LFX, LMX, LSC, or LRSC and uses an internal twist-in filter, the LT500P is likely your correct filter. Always verify by checking the part number on your current filter before ordering. If your current filter is a different LG model number (LT600P, LT700P, LT800P, or LT1000P), you need a different filter.

3. Prepare New Filter: Remove the protective cap from the new filter. Do not remove any seals or o-rings
4. Install New Filter: Insert the new filter and rotate it clockwise approximately a quarter turn until it locks firmly into place
5. Flush the System: Run water through the dispenser for approximately 2 gallons (around 5 minutes) to flush air and activate the carbon block. Water may appear slightly cloudy initially — this is normal
6. Discard Initial Ice: Discard the first batch of ice produced after installation
7. Reset Filter Indicator: Reset the filter replacement indicator on your LG refrigerator's display. Press and hold the appropriate button (varies by model — refer to your owner's manual)

Frequently Asked Questions

How do I know if my LG refrigerator uses the LT500P and not a different LG filter?

Check the part number on your current filter — it will be printed on the label. If it reads LT500P, 5231JA2002A, ADQ72910901, or ADQ72910911, this is the correct replacement. LG makes several different filter models (LT500P, LT600P, LT700P, LT800P, LT1000P) and they are not interchangeable. If your current filter has a different LT number, you need a different filter.

Are LT500P and LT500PC the same filter?

Yes. The LT500P and LT500PC are the same filter — the "C" suffix simply indicates a color variation (typically white vs. a different finish). Both versions are fully interchangeable and will fit the same refrigerator models.

Is the LT500P compatible with Kenmore refrigerators?

Yes. Select Kenmore refrigerators that share LG's manufacturing platform use the LT500P filter under Kenmore part numbers 46-9890, 9890, and GEN11042FR-08. Check the label on your current Kenmore filter to confirm before ordering.

Where is the LT500P filter located in my refrigerator?

The location varies by model. In most LG side-by-side and bottom-freezer refrigerators using the LT500P, the filter is located inside the refrigerator compartment — typically in the upper right area or at the base of the fresh food section. Refer to your owner's manual for the exact location in your specific model.

How do I reset the filter indicator after replacing the LT500P?

The reset method varies by model. On most LG refrigerators, you press and hold a "Filter Reset" or "Reset Filter" button on the control panel for 3-5 seconds until the indicator light changes or turns off. Refer to your owner's manual for the specific reset procedure for your refrigerator model.
