Optimum Temperature

We all know water freezes at 32°F, or 0°C. Your ice maker has an optimum temperature that will hit the right balance between making ice quickly and using just the right amount of energy.


-4°F (-20°C) is the minimum recommended temperature setting of the freezer compartment for normal ice production.

If your freezer is set at a higher temperature, it will produce ice.

The ice capacity of your ice maker varies by model, but a good rule of thumb is 90 to 150 cubes per day.

Making More Ice

Having an automatic ice maker will make your daily life more convenient. Here are a few tips on how to get the most out of it.

  • Ice-making stops when the bin gets full. If you
    need more ice, empty the ice bin into the extra
    container in the freezer and you are good to go.
  • Sometimes the ice piles up near the top of the ice
    maker, causing it to sense the bin is full and stop
    making ice. Shake the bin to level the ice in it.
  • Regulate the cube size by pressing the Water
    Amount Selection button. More water means
    bigger cubes, which need more time to
    become ice.
  • Lowering the temperature helps to make ice
    more quickly, but also try not to open the
    freezer doors so much.
  • If you think you'll need a lot of ice, turn on the
    ICE PLUS feature. This makes the compressor
    operate nonstop for three hours and increases
    ice production by 20%.

Maintaining Your Ice Maker—The Dispenser
  • When using the dispenser, it's safe to keep your distance from the ice outlet.
  • Alternate your dispenser between cubes and crushed ice to avoid the ice passage getting blocked with frost. And remember to clean the frost that accumulates.
  • Be gentle when pushing the lever on your dispenser so it doesn't get stuck. If it does, try to push in delicately and then release.
  • Air bubbles can create pressure and cause a constant drip. To flush air bubbles out, dispense 2-3 gallons of water and then check again.
  • The ice maker goes into auto defrost mode twice a day. So don't worry if water seems to appear in the drip tray out of nowhere. It's just the ice melting near the funnel.
  • Check to see if the dispenser flap is closing properly. The cold air escaping from the freezer could cause condensation—and leaking into the dispenser tray.
  • When you turn the ice maker off, remember to empty the ice bin so ice doesn't melt and drain through the dispenser.
  • The error codes "Er FF" or "Er IF" may be the results of ice or freezer-frost buildup.
Maintaining Your Ice Maker—The Freezer
  • Check the water lines at the back of your refrigerator for bends or leaks that could be reducing the water flow to the ice maker. If the water lines are bent, straighten them out.
  • Don't set your freezer temperature under -4ºF (-20ºC). This may cause ice to build up on the feeler arm and on the tube leading to the ice maker.
  • Before you activate the ICE PLUS feature, set the freezer temperature to at least 0°F (-18°C), or colder.
  • If you find sheets of ice forming in the bottom of your freezer, it could be caused by water overfilling or overshooting the ice maker ice tray. Make sure the ice bin is installed correctly.
  • Look for containers that are not completely sealed and could leak.
Maintaining Your Ice Maker—The Ice Maker
  • Storing cans or other foods in the ice bin for rapid cooling may damage your ice maker. Check the feeler arm periodically by moving it up and down. If it moves, it's not frozen. If it is frozen, you can use a soft, warm cloth and wrap it around frozen parts until they thaw. The same goes for the tube to the ice maker.
  • If you get discolored ice, check the filter and water supply. If the problem continues, contact an Authorized Service Center.
  • Don't remove the ice maker cover.
  • Keep your fingers out of the ice door and ice passage.
  • From time to time, check to make sure there's no ice on the tray or feeler arm preventing the return of the arm to upright position.
  • Clean the ice tray and bin to prevent particles from forming in ice.
  • To keep your ice tasting fresh, remember to change the filter every 4 to 6 months.
  • If the water pressure in your ice maker is too high, water could overshoot or overfill the ice tray. Reduce the size of the cubes using the selector on the ice maker.
