While on the road with our fifth wheel we noticed water on the shelves and vegetable bins of our fridge. Along the back wall there is this trough like thing with some rubber tubing attached. The other end of the tubing goes through the back of the fridge to only God knows where. A closer inspection revealed that the tubing was not really attached to the aforementioned trough like thing. Finally an easy fix, just reconnect the two. I needed a little more room to maneuver, easy enough, just have to remove the shelves. Guess what? Nothing is easy! Shelves in the fridge are screwed down. Fortunately we own a screwdriver.
Much to my horror the tube was too short to properly connect to the thingy! Yanking on the tube was a scary prospect because I didn’t know where the other end hooked up. I certainly wasn’t going to pull the fridge out, if the shelves are screwed in imagine how the fridge must be attached to the wall. I was not about to find out. Nor did I want to mop out the fridge every day or worse have it start to leak outside the fridge. Water and rv’s don’t go well together. Ever so gently I started pulling on the tube. I was able to gain another inch before I met any resistance. I secured the hose to the thingy and put the shelf back in. Monitored it closely for the next few days and the problem seemed to be resolved. Go Me!
But the water came back. We didn’t need to build an Ark but it was definitely back. The hose was still affixed to the thingy but the thingy was full of water to the point of overflowing. Obviously the tube was blocked, I tried squeezing the tube but that did nothing. Faced with the end of my knowledge of all things fridge I did the only thing left. Google.
Google, in all its web hive wisdom told me the tube was blocked. Google told me to go outside the rv and remove the panel behind the fridge and check the end of the tube. Sounded like a plan. There, amongst a bunch of wires and something that looks suspiciously like a motor was a tube that looked exactly like the one in the fridge, it traveled up the wall and vanished. I surmised that what I was looking at was the other end of the tube. There was a black plug wedged into the opening of the tube. Using my knife I carefully worked the plug out of the tube. What I did not do was step out of the way and in seconds the tube was peeing fridge water all over me. Still holding the black plug I went back and checked inside the thingy and now it was empty of water. The question now, ‘why is there a plug in the end of the tube?’ It was obviously there for a reason but the tube could not do its job with a plug in one of its ends. I asked Google. I found two articles on the plug at the end of the tube in an rv fridge. Both said to keep the plug in place. The first reason made sense, it kept ants out. The second reason said it regulated the temperature. I do not have any faith in the second reason but I was not about to take any chances. Nobody is going to blame me for climate change because I failed to replace the dreaded tube plug. With great regret I put the plug back in the tube but didn’t jam it in, just a nice loose fit, perhaps the water is supposed to ooze around the plug?
A few days later the thingy in the fridge was overflowing. I ran around the rv, took off the panel looked at the motor, wires and took the plug out of the end of the tube (standing away from it this time because sometimes I learn) and fridge water came peeing out of the tube. I figured that this wasn’t right, but wasn’t the end of the world and every few days I’ll just pull the little plug.
While it wasn’t a difficult task it did get annoying after a few weeks. So I went back to google and all the Googlemyster could suggest was that the drain tube was plugged. Arrrgh! Of course it is plugged there is a plug in the end of it that I’m not supposed to remove because it may alter the temperature. My lovely wife suggested I ask about it on an RV web site we belong too.
Must have been 1am when I started to pose my question on the web site. When all of the sudden it hit me. Maybe there was supposed to be a hole in the plug itself! Could it be that simple? I jumped up tripped over the dogs, which woke my wife, I explained that I had to go investigate the plug. By the glow of my flashlight I opened the panel that housed the motor and wires and removed the plug and brought it inside the rv and began my investigation. The plug looked solid but there was also a slight recess inside it. I took a tooth pick, and this folks, is the most amazing part of the story, the part that we have all been waiting for, the part that inspired me to write this long winded story about a drain tube in a fridge. (Drum Roll) Not only did we have toothpicks, I actually knew where they were!
And you know what? With that toothpick I found a little piece of fridge debris inside the plug that was blocking the tiniest of holes. A hole just large enough to let water seep though. We have not had water in the thingy since.
