How to replace the LT600P

  1. Find the filter. Its location varies by model (inside the fresh-food compartment, in a door, or behind the bottom grille); your owner's manual shows where.
  2. Remove the old filter using the method printed on the filter, its packaging insert or your manual. Keep a towel handy.
  3. Install the new filter the same way until it is fully seated and locked.
  4. Run water through the dispenser for a few minutes to flush out air and carbon dust.
  5. Reset the filter indicator as described in your manual (on many models, hold the filter button for about 3 seconds).
