While most ice maker kits are quite similar, there may be slight differences, depending on the type of ice maker kit you’ve purchased. That being said, we’ve laid out the most general and common ice maker installation steps available.

Step 1: Run the Water Line

In order to run the water line, you must make a hole behind your refrigerator with a drill. Next, drill another hole underneath the sink. Dip down into the opening and feed the line down the crawl space and then back up through the hole you made in your refrigerator.

Step 2: Drain the Water Line

After you have the water line running into the refrigerator, you can tap into the cold water line located under the sink.

In order to do this, shut-off the water valve to the entire house at the main source.

NOTE: With any type of plumbing project, the electric heater at the breaker should be turned off if the main water supply has been shut off as well. If your heating system is gas-powered, push the switch to the position reading “pilot”.

Next, open a faucet to drain the remaining water from the lines.

Step 3: Install the Valve

Install the new valve made for the icemaker’s water line.

It should be noted that there are quite a few different types of valves that could be used for this job.

A needle valve is recommended. In order to install a needle valve, put two clamps around the pipe, then tighten the screws on opposing sides with a screwdriver to hold it in place.

Tighten the “T” handle so that it is tight against the copper line.

Step 4: Install the Solenoid Valve

One of the first parts you’ll receive in an ice maker kit is the solenoid valve. Attach the solenoid valve to the cabinet frame holes within the fridge by using two screws and a drill.

Find the solenoid connector which is usually under the refrigerator and put the connector over the valve solenoid inserts.

Step 5: Connect the Water Supply Line

Take the water supply line and connect it with the compression fitting that is provided, to the top of the solenoid valve. This can be done by screwing it in.

Next, screw the plastic tube that comes with kit onto the water outlet which is located on the bottom part of the solenoid valve.

Use the adhesive clips that are provided to bring the water line to the back end of the freezer. Make a hole at the back of the unit in the paper cover with a screwdriver.

Step 6: Install the Factory Fill Tube

Take a flathead screwdriver and remove the plugs from the factory fill tube holes. Install the fill tube by taking the metal insert that was provided into the water supply line. Tighten everything with a drill. Slide the fill tube into the inlet hole at the back of the freezer. Screw in place.

Step 7: Install Your Icemaker

Plug the writing harness found on the side part of the ice maker into the wiring at the back end of the freezer wall. Take the extension tube and insert it into the small hole at the back wall of the freezer.

Step 8: Hang Ice Maker to the Wall of Your Freezer

Hang the icemaker over the screws, ensure you line up the extension the. Tighten screws to secure ice maker to the wall. Next, install ice bucket.
