Kenmore refrigerators are a popular choice for many households thanks to their reliability, spacious designs, and efficient water and ice systems. However, replacing the water filter often leaves owners confused about which part number is correct. If you have seenΒ 9990, 46-9990, or related numbers while shopping for a replacement, this detailed guide will help you confidently determine if this is the right filter for your refrigerator.

This informational blog post explains everything you need to know compatibility, key differences, installation process, maintenance tips, and common pitfalls so you can make an informed decision and keep your water and ice fresh and clean.

Why Kenmore Water Filter Numbers Can Be Confusing

Kenmore uses a wide variety of filter part numbers across different refrigerator lines and manufacturing years:

  • Older models often use filters like 46-9010, 46-9083, or 46-9030.
  • Newer Kenmore Elite models commonly use the 9990 / 46-9990 series.
  • This filter is cross-compatible with LG LT600P, 5231JA2006A, and similar part numbers.
  • Many listings show multiple numbers (9990, 46-9990, LT600P) to cover broader compatibility.
  • Some refrigerators were built by LG for Kenmore, which adds another layer of part number variations.

Using an incorrect filter can result in leaks, poor sealing, reduced water flow, or insufficient filtration. Understanding your specific model helps avoid wasted money and frustration.

Where to Find Your Kenmore Water Filter Model Number

Identifying the correct filter is simple when you know where to look. Follow these steps:

  1. Check the old filter cartridge β€” Remove the current filter and look for 9990, 46-9990, or 469990 printed on the label. This is the most accurate method.
  2. Inspect the filter housing β€” The filter is usually located in the top right section of the fresh food compartment or behind the base grille.
  3. Review your refrigerator manual β€” Search for β€œwater filter,” β€œKenmoreClear,” or β€œreplacement cartridge” in the owner’s manual.
  4. Locate the model plate β€” Found on the inside wall or ceiling of the refrigerator. Use your full Kenmore model number for verification.
  5. Use official parts lookup β€” Visit Sears Parts Direct or the Kenmore website and enter your refrigerator model number.

Most Kenmore models with this filter have a filter status indicator light on the dispenser panel that alerts you when it is time to replace the filter.
