How to Replace an Ice Maker on a Bottom Mount Freezer

Replacing an ice maker on a bottom mount freezer can seem daunting, but it’s a task that most homeowners can handle with the right tools and instructions. This guide will walk you through the process step-by-step, making it easy for you to troubleshoot and fix your freezer’s ice-making capabilities.

Tools and Parts You’ll Need:

  • Phillips head screwdriver
  • Flathead screwdriver
  • Wire cutters (optional)
  • New ice maker (make sure it’s compatible with your freezer model)

Step-by-Step Instructions:

  1. Unplug the freezer: This is crucial for safety. Ensure that the power is completely disconnected before you start working on the appliance.
  2. Locate the ice maker: In bottom mount freezers, the ice maker is typically located in the top section of the freezer compartment. It’s often behind a removable panel.
  3. Remove the old ice maker:
    • Start by disconnecting the water line. This is usually a small, flexible tube connected to the ice maker. You may need to use wire cutters to snip the tube if it’s secured with a plastic clip.
    • Locate the ice maker’s wiring harness. Disconnect the wires from the ice maker. You might need to press down on the tabs on the connector to release the wires.
    • Remove any screws holding the ice maker in place. Once the wires and water line are disconnected, the ice maker should be free to remove.
  4. Install the new ice maker:
    • Connect the water line to the new ice maker. Ensure it’s securely connected and free of any kinks or leaks.
    • Connect the wiring harness to the new ice maker. Make sure the wires are properly connected and secured.
    • Reinstall the ice maker in its designated spot. Secure it with the screws you removed earlier.
  5. Test the new ice maker:
    • Reconnect the freezer to the power outlet.
    • Allow the freezer to cool down and reach its operating temperature.
    • Check if the ice maker is working properly. You should hear a slight humming noise as the ice maker cycles, and you should see ice cubes forming within a few hours.

Tips and Troubleshooting:

  • Check the water pressure: Ensure that the water pressure to the freezer is adequate. Low water pressure can affect the ice maker’s performance.
  • Clean the ice maker: Regularly clean the ice maker to prevent mineral buildup and ensure optimal performance. This can be done by removing the ice maker and rinsing it with warm water.
  • Check the water line: If the water line is kinked or damaged, it can prevent water from reaching the ice maker. Inspect the water line for any issues and replace it if necessary.
  • Replace the ice maker’s fill cup: The fill cup is a small plastic piece that sits inside the ice maker. Over time, it can become cracked or damaged, preventing the ice maker from filling with water properly. Replace the fill cup if needed.


Replacing an ice maker on a bottom mount freezer is a relatively simple task that can be accomplished with a few basic tools and some patience. By following these instructions, you can get your freezer back to making ice in no time. Remember to always prioritize safety by unplugging the freezer before working on it. If you encounter any difficulties or have concerns about the process, consult a qualified appliance technician.
