Check the following parts if your Norcold refrigerator is leaking water:

1. Drain Tube

 The drain tube runs from inside the refrigerator to behind the refrigerator where it is directed into the drain pan. The drain tube takes out condensate water from the refrigerator. This tube can get clogged and cause water to go back into the refrigerator.

In this case, locate the drain hole inside the refrigerator and insert a long thick piece of wire or a drain cleaning tool to clean the drain. Afterward, sprinkle baking powder into the hole and use a syringe to pour warm water down the drain.

2. Drain Tube Plug

At the end of the drain tube is a little rubber plug inserted into the tube. The plug helps to keep warm air, critters, and tiny insects out of the tube. This plug has a tiny opening through which the water comes out from. But the plug can become clogged and so the water will begin to go back up the drain tube.

To stop the leak, the plug has to be removed and cleaned. The steps below will guide you on how to do this:

Step 1: Go to the back of the RV and remove the refrigerator back access panel.

Step 2: The drain tube is mostly white and made of rubber. So it should be easy to tell it apart. Look at the end of the tube and you will see the plug. Pull out the plug from the tube.

Step 3: You can apply several methods to clean out the plug. You could clean it with warm water and baking soda. You can also blow on the bottom of the plug to remove the clog. Or simply run water down the plug.

Step 4: Once the plug is completely clean, take it back to the drain tube and reinsert it. Go back inside the refrigerator and flush water down the drain hole. Ensure the water is going down the tube as it should.

Step 5: If all is working well, put the access panel back in place.

3. Door Seal

Condensation is one major reason your Norcold refrigerator can start leaking water. And one way condensation occurs is if the refrigerator is not sealed off properly. That is where the door seal comes in, as it is responsible for ensuring the door is sealed properly at all times.

However, the seal may fail at its job if it is dirty or has holes and leaks in it. Open the fridge and inspect the door seal. If it is dirty, then you can clean it up using any of the following methods:

i. Alcohol, gauze, and a card

Dip the gauze in the alcohol. And then, place the gauze on the card, put the card and gauze on the door seal, and swipe around it.

ii. Mild Detergent, Water, and a Dishtowel

Ensure the detergent is not mild as one too harsh can damage the seal. Dab the dishtowel in the detergent and water solution and then clean the seal as best as possible.

If the detergent is not dirty then it most probably is damaged. To check this, place a dollar bill or any flat piece of paper on the refrigerator’s door and close the door. Try to pull out the bill or paper. If it pulls off without any resistance then the seal is bad and should be replaced.

Step 1: Remove the old seal by peeling it off the track. If peeling it is difficult, place a putty knife at the top corner of the seal and run it around the track. This should effortlessly peel off the track.

Step 2: Inspect the track and ensure there is no remnant of the old seal on it.

Step 3: Take the new seal; it should be a perfect fit with your refrigerator. Clip it around the door. Press it in firmly to ensure it stays put.

Step 4: Finally, check the seal and ensure it has no bumps or folds.

Norcold Ice Maker Leaking – Solutions

The following are solutions to your Norcold ice maker leaking:

1. Reset the Water Volume

To reset the water volume, the ice maker has to be removed since the set screw is behind the ice maker.

To do this, unthread the screws holding the ice maker in place and gently pull it out. Use a Philip or flat head screwdriver to turn the set screw clockwise to reduce the water volume. Put the ice maker back in place and see if the leak is fixed.

2. Replace the Water Inlet Valve

If resetting the water volume does not stop the leak, then the water inlet valve may be defective. To troubleshoot the valve, go behind your RV and take off the refrigerator’s panel. Use a multimeter to test for resistance in the valve. If there is none, the valve is defective and most properly stuck open.
