Most modern refrigerators come with pre-installed ice makers, but you can purchase a kit from any home improvement store if yours doesn't come with an automatic ice maker.

With some plumbing and electrical know-how, you can easily install the ice maker and enjoy its convenience!

What You Need

To install an ice maker in your freezer, ready the following items:

  • Ice maker kit
  • Power drill
  • 1/4-inch nut driver
  • Screwdriver
  • Adjustable wrench
  • Measuring tape
  • Pliers

Step 1. Prepare the Area

Before starting the installation, ensure that the refrigerator frame and the back wall where you will install the ice maker are clear and clean.

Clear out any items from the freezer compartment and clean the area around the tube opening where it will be installed.

Step 2. Gather the Necessary Materials

Secure all the necessary materials, such as the ice maker kit, power drill, nut driver, screwdriver, adjustable wrench, measuring tape, and pliers.

Select a kit that is compatible with your refrigerator model*. Make sure to choose one specifically designed for your refrigerator brand and model.

Check the instruction manual in the ice maker kit to ensure you have all the necessary parts.


The model number can usually be found in the user manual for your freezer or on the manufacturer's website.

Step 3. Turn Off the Power and Water Supply

Cut the electrical connection of the refrigerator before starting the installation process. This is for safety purposes to avoid any electrical hazards.

Before installation, turn off the water supply to the freezer and refrigerator. This can be done by turning a water valve under the sink or near the main water supply line.

If you're unsure which valve to turn off, deactivate the whole house water supply to be safe.

Step 4. Install the Ice Maker

Begin by locating the water inlet valve and the mounting holes.

It is typically on the back of the refrigerator, near the bottom. It should have a small plastic or copper tube that runs from the water valve to the refrigerator.

(You may need to mount it in a lower position of the refrigerator if it's a bottom freezer type.)

Take the mounting screws included in the kit and attach them to mounting holes in the freezer wall. Use the nut driver to tighten them enough to hold them in place.

Step 5. Connect the Water Supply

Next, you will need to connect the water supply. This involves attaching the water supply line to the water inlet valve at the back of the refrigerator.

Take the compression nut and sleeve from the kit and slide them over the water supply line. Then, insert the line into the valve and tighten the nut using the adjustable wrench.

Alternatively, saddle valves can tap into the cold water pipe under the sink or near the refrigerator. Follow the instructions in the kit to attach the water supply line to the valve.

Be sure to use a nut driver to tighten the compression fitting on the water valve, but don't over-tighten it, as this can damage the fitting.

Step 6: Run the Water Line

To run the water line, you must drill a hole in the side of the cabinet or the floor behind the refrigerator. This is so the water inlet tube can go through the correct "wall."

Measure the distance from the valve to the hole and add a few extra inches for slack. Cut the tubing to the appropriate length and attach it to the valve using compression fittings.

Pull the tubing through the hole and connect it to the ice maker using the compression nut and sleeve.

Attach the water inlet tube to the back of the refrigerator by inserting it into the tube opening and securing it with a compression nut. Next, wiring harnesses need to be attached.

Connect the wiring harness with caution! Plug the wiring harness from the ice maker assembly into the wire harness opening on the back of the refrigerator.

If your refrigerator doesn't have an opening for a wiring harness, you may need to remove the plastic cover to access the wiring.

Step 7: Attach the Fill Tube

Attach the fill tube to the back of the ice maker. Use pliers to adjust the tube to the proper height and secure it with the mounting screws.

Make sure the water inlet tube is inserted into the fill cup and that it is properly aligned.

Step 8: Connect the Power Cord

Plug the ice maker's power cord into an electrical or wall outlet.

Make sure the electrical connection is grounded correctly and that it is not damaged.

Step 9: Turn on the Water Supply

Turn on the water supply valve and check for leaks.

If you notice any leaks, tighten the connections or adjust the tubing until the leaks stop.

Step 10: Level the Ice Maker

Finally, level the ice maker using the leveling bracket included in the kit. Adjust the bracket until level, and secure it with the mounting screws.

Fill the fill cup with water to test. Wait a few hours to see if the ice maker produces ice cubes. If it does, you have successfully installed it.

What Are Ice Makers?

Ice makers are devices installed in a freezer to produce ice automatically.

They are connected to the water supply line through a water inlet valve, usually located behind the refrigerator.

The ice maker consists of a fill tube, an inlet tube, and a valve controlling the water flow.

The installation involves mounting screws to secure it to the freezer wall and connecting the water supply line to the inlet tube using a compression nut.

Once installed, it automatically fills the tray with water and freezes it, creating ice that can be accessed through the refrigerator pull.

Why Should You Install an Ice Maker Kit in Your Refrigerator?

If you choose to install this device, it can offer lots of benefits which include:

  • It provides a convenient and reliable source of ice that can be accessed from the refrigerator pull without having to refill trays constantly.
  • It also frees up freezer compartment space that these trays would otherwise take up.
  • It is connected directly to the water supply line, so there's no need to constantly refill a water source.

We think it's a great addition to current refrigerators and makes entertaining guests a breeze.

What Are Good Ice Maker Kits to Get?

When it comes to adding an ice maker to your freezer, the right gear can make all the difference!

There are many factors to consider, from selecting the appropriate tube and pipe sizes to finding the proper pull, hole, and plug placement.

We'll break down a quick guide on choosing the perfect ice maker for your needs.

Selecting an Ice Maker

Keep these in mind when making your purchase decision:

  • Compatibility with your freezer or refrigerator. Ensure your freezer or refrigerator is compatible with the device.
  • Freezer size. Consider the size of your freezer compartment to determine if it will fit.
  • Production capacity: Check the production capacity to see if it can meet your needs.
  • Water connection. Look at how it connects to the water supply line, whether through a saddle valve, water inlet tube, or water line.
  • Mounting materials. Verify that it comes with all necessary mounting screws, plastic plugs, etc., and is secured with a hygienic plastic cover.
  • Ease of installation. Consider how easy it is to install and whether special tools, such as compression fittings or a leveling bracket, are needed or included.
  • Water supply valve or water valve. Ensure that a water supply valve or a water valve can access a cold water pipe.
  • Fill tube. Check if it comes with a fill tube to deliver water.

How Much Does It Cost to Hook up an Ice Maker on a Refrigerator?

Generally, the cost to install a basic ice maker ranges from $150 to $500, but it can vary depending on several factors, such as:

  • The device's price can depend on the brand and model chosen.
  • The overall cost can be higher if the necessary water line and supply line are not already in place.
  • In some cases, to install, it may be necessary to purchase additional mounting screws, a leveling bracket, and a water inlet to accommodate the device.

It's important to factor in any required tubing, line, and plug costs.

Remember that you may need to drill holes into your cabinetry to install the ice-making device.
