Our Dometic RM-3762 fridge has been leaking water inside. As the coils cool the fridge, water condenses and lands on the drip tray. (We have the Fridge Fix installed, so we don’t get any frost on the fins, but we still get condensation.) Theoretically, that water should be directed through the drain tube, and out the bottom of the Airstream, but instead it’s been finding its way to the bottom of the fridge.

Water that is supposed to be going out of the drip tube is just running down into the bottom of the fridge. Removal of the drip tray shows the obvious problem.
The drain from the drip tray goes into a larger horizontal pipe in the back of the fridge. I’m not sure how this was ever supposed to work. There’s no seal, and the water doesn’t end up far enough back to continue down the drain tubing. It just backs up into the fridge.
Fortunately, the solution is easy. A short piece of 3/8” OD (1/4” ID) vinyl tubing (about 2-1/2” long) fits over the drip tray tube, and routes the water far enough inside the drain to prevent it from backing up into the fridge.
It’s been a few days since the modification, and the bottom of our fridge is bone dry.
