Make sure the control arm or infrared beam isn't obstructed.

  1. It's a metal bar that spans the length of the ice tray. Others have an infrared beam that senses when the ice is full. Remove the ice tray and make sure there is no stray ice preventing the control arm from rotating or blocking the infrared beam.
    • Some ice makers have a removable bucket that sits under the maker. Others have a tray that slides in and out of the ice maker compartment. If your refrigerator has an ice maker compartment in the upper-left corner, press the release button on the ice maker and pull the ice tray out.

  1. Make sure there is no ice blockage in the chute or ice ejectors. Clear out any ice clogging the dispenser or ejectors with a plastic knife or allow your freezer to defrost.
    • Check to make sure the chute that ice drops through is clear of any ice that may be obstructing it.
    • Check that the ice mold isn't overflowing with ice above or below and that there isn't any ice blocking the ejector arms above the ice mold from ejecting ice.
    • If you have an ice tray that has a metal augur on the inside, make sure there aren't any large ice clumps keeping the augur from moving.
    • You can defrost ice using a hair dryer.

Check the water line for damage or clogs.

  1. If there is a problem with the water line, it will prevent your ice maker from receiving the water it needs. The water line is a small plastic or copper tube that connects the water faucet to the water valve on the back of the refrigerator. Check the line for leaks, kinks, or clogs. Water leaking inside the freezer could be a sign of a water line leak.
    • Also check to make sure the faucet the water line is connected to is turned on and that there is no leak where the hose connects to the faucet.

Check the water valve for damage or leaks.

  1. The valve is usually located on the back of the refrigerator where the water line connects. The water pressure from the valve needs to be at least 20 psi for it to function properly. If the valve is leaky, the ice mold may overfill. If it is damaged, it may not open to allow water to flow. Replace the water valve if need be. [1] To replace the water valve:
    • Turn off the water and disconnect the water line. Then remove the back panel from your refrigerator and remove the valve mounting bracket.
    • Remove the wire harness and the valve assembly. Attach a new assembly to the wire harness and mount the new valve assembly.
    • Reattach the back panel, along with the water line, and turn the water back on. [2]

Check to see if the water filter needs to be replaced.

  1. If you do not, the water filter may become clogged with sediment which will restrict water flow to the ice maker. If the water pressure is low or your ice tastes funny, it might be time to change the water filter.
    • Check the documentation that came with your refrigerator to learn where the water filter is located and how to change it.
    • Some after-market filters may not work as well as the one that came with your refrigerator. Make sure you get a water filter that is right for your refrigerator model.
