How to replace the BORPLFTR55

  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. Turn the old filter counterclockwise about a quarter turn and pull it straight out. Keep a towel handy for drips.
  3. Remove the protective cap from the new filter, line it up, push it in and turn it clockwise until it locks.
  4. Run water through the dispenser to flush out air and carbon dust, following the volume in your manual (often 2-4 gallons).
  5. Reset the filter indicator light (usually by holding the filter or reset button for about 3 seconds).
