Dometic RV Fridge Leaking Water – Why and Solution

The most common reason Dometic RV fridges leak is a damaged or clogged drain tube. The drain tube carries condensate water out of the refrigerator. If the drain is damaged or clogged, the water meant to go out of it will run back up and spill out.

Therefore, the solutions to your Dometic RV refrigerator leaking water are:

1. Unclog the Drain Tube

Do the following to unclog your Dometic RV fridge drain tube:

Step 1: Locate the drain tube’s entrance inside the refrigerator. Take off the first shelf and then the tray just underneath the cooling fins. The tray may be filled with ice; this is an indication that the drain tube is blocked.

Step 2: With the tray removed, you will have no problem locating the drain tube’s entrance. Depending on your model, the entrance may be a hole in the refrigerator. Or a little tray with a receptacle that houses the drain tube.

Step 3: If your model has a hole as the tube’s entrance then make a mixture of baking soda and warm water. Then use a turkey baster or syringe to flush the mixture down the hole. Do this until the drain is completely free of clog. And then put the tray and shelve back in the refrigerator.

Step 4: If you have a model with a receptacle, use a screwdriver to pop it out. Once you have it out, remove the drain tube. Take the tube to your kitchen sink and flush water down the drain. Insert the tube back in the receptacle and reinstall it in the fridge.

2. Replace the Drain Tube

The tube is likely damaged if unclogging it does not stop the leak. In which case, the tube has to be replaced. To do this, simply remove the receptacle from the fridge. Disconnect the tube from the receptacle and then put a new one in its place.

If your refrigerator has a hole at the entrance of the tube, you may find it difficult to replace the tube. However, you can add a vinyl hose to the damaged tube to stop the leak.

Follow these steps to replace the drain tube:

Step 1: Go outside the RV and locate the access panel of the refrigerator. Unthread the screws holding the panel in place.

Step 2: Locate the drain tube and inspect the damage. Usually, the damage is often due to the plastic with which the tube is made up crumbling due to UV exposure.

Step 3: Get a vinyl tubing that would easily go into the tube and also sit snugly in it. Cut the vinyl to a length that is sure to go out of the back panel. Insert the vinyl into the tube and properly secure it. Do this carefully to prevent the drain tube from crumbling.

Step 4: Inspect the work to ensure the connection of the drain tube and vinyl is not leaking. Finally, once you are satisfied with your work put the access panel back in place and thread the screws in.

Dometic RV Refrigerator Leaking Ammonia – What to Do

The first thing to do if your Dometic RV refrigerator is leaking ammonia is to call a repair technician. Your refrigerator leaking ammonia will mean that the refrigerator’s cooling unit is leaking. This is also the same problem if a Dometic fridge is leaking yellow fluid.

This problem is not one that you can easily fix by yourself because of the dangerous nature of ammonia. Another reason is the complex nature of the repair.

However, if you have had the refrigerator for a while, you may decide to replace the whole unit altogether. Because repairing the unit and getting a new unit may run at almost the same cost.
