As the summer approaches and the temperature gets higher and higher there are going to be many of you out there that notice your refrigerator isn’t getting cold enough anymore. Most commonly we hear that the freezer is working just fine but the refrigerator isn’t quite getting to temperature. Most likely the culprit is a lowering of the pressure inside your cooling unit. As small pinholes start to develop in the steel coil the pressure will slowly drop off. In the cooler temperatures of the fall and winter these low pressures are not as evident because it doesn’t take as much effort to cool the ammonia gas due to the ambient air temperature. As the
Every refrigerator on the market today has a drain line to allow condensation and runoff to be funneled out of the food storage area to the outside of the coach or camper. We all know that these drain lines need to empty out of the coach or into a drain pan of some kind so that the water doesn’t rot out the platform and wall underneath and behind the refrigerator. However, there is a little known fact about these drain tubes that you should be aware of. There is typically a stopper or cap installed at the end of these drain lines and many times the owners remove them to allow more water to flow
You may have been advised to “move your thermistor probe” to help adjust the temperature inside the food compartment of your refrigerator. If so, you may have also wondered “What is a thermistor?” and “Why does moving it to a different area make a difference?”. Wonder no more fore here is the answer. A Thermistor is a simple resistance based thermal probe that changes resistance based on the ambient air temperature. The control board it is plugged into will read that resistance and turn on, or off, the heat source as needed to maintain a constant temperature. As these probes begin to deteriorate the resistance may slowly become out of the range it should be
One of the most common questions we get is “Should I replace this old 2-way ammonia absorption refrigerator with a residential Freon refrigerator?” If there was a straight forward answer I would gladly give it, however there isn’t. There are many factors that need to be considered. How do you use your camper, how long do you plan on keeping it, and how much customization will need to be involved on your existing cabinetry and electrical system. I’ve made a flow diagram to help guide you (link below). residential-decision-tree If you still aren’t sure give us a call at 256-784-5097 and we’ll be happy to discuss it further.
Do you see ice or excessive water dripping from the top of your refrigerator? You have a condensation problem! The biggest culprit of condensation is an air gap at the door gaskets. Check your gaskets for any obvious tears or cracks, if you are unable to see the problem use the “dollar bill trick”. Take a dollar bill and close it in the door, you should feel resistance but be able to slide the bill easily. Slide the dollar bill all around the door, if at any point the bill moves between the gaskets without healthy resistance you have a gap. For some models you can simply adjust the door or replace the gaskets. For other models (Norcold 12 cubic ft models) you
