Pennsylvania RVers, do not loose your cool!

Your refrigerator is your most important appliance when it comes to your RV. Some of the advantages to having a refrigerator is not having to haul coolers around. Which means no more refilling the ice, emptying out water from melted ice, and lugging it place to place. These are the advantages to remember when it comes to keeping  your fridge working and not loosing its cool.

There can be several reasons that refrigerators will fail to work correctly. With these various reasons, it is in the best interest of RV owners to know when to repair vs. replace. Typically, there are two brands of refrigerators located inside of RVs, Norcold or Dometic. Those brands run with the same concept. They operate by heating a closed cooling element with a gas flame or electric heating element. The cooling consists of ammonia-based liquid that is contained within a series of tubes. When the heat is added, the ammonia-based liquid will circulate through the closed cooling unit by releasing the heat out of the refrigerator.

When the fridge stops cooling as well as it should this means that the circulation of fluid is not working properly. One advantage to RV refrigerators is that there are no moving parts other than the heating liquid, making it easier to find the problem. Some common troubleshooting refrigerator Q & As are contained within this video.


Frequently the problem with RV refrigerators is time combined with lack of use. As the units age, the liquid will create a sediment that will settle at the bottom of the cooling unit. As this sediment builds up, the ability for your fridge to be cooled properly will decrease because the circulation will be hindered. When comparing a fridge that is used once or twice a year in a time frame of 5+ years, and a fridge that is in continual use, the fridge in continual use will be less likely to plug up. Any sediment build up that could occur will be delayed with the more frequent fluid movement.

The tall-tale of removing your RV refrigerator and turning it upside down for a time period to have it work again is questionable. The theory behind this is only somewhat explainable. When sediment occurs, it is possible to dislodge it for some time, but when it sits back in place again the sediment will settle and plug up the tubes once more.

Rebuilt cooling units are available for purchase but they are expensive and when added with the labor costs, it can be a pricey project that could have easily been spent on a brand new refrigerator.

The three steps below are a quick guide to make sure your RV refrigerator is working properly. You may have a Dometic or a Norcold refrigerator. Most, if not all, refrigerators found in all RVs are produced by one of those companies. The steps below will work on which ever make or model you have.

Step 1: Ensure the refrigerator is sitting level. All you need to do is set a level on the top of the refrigerator. Sometimes RV refrigerators will not work properly if they are not sitting level. If the level indicates that this refrigerator is not level, simply move your RV to flatter land. If it is sitting level, you can rule this out as the problem.

Step 2: Test the settings. If the refrigerator will only operate in 120-volt, make sure the on-board battery is operating correctly. If not you should replace it. If the refrigerator will only operate in gas mode, check the breaker to which it is connected. If it operates only in electrical mode, check the burner’s pilot light. Simply open the access panel and relight this pilot light.

Step 3: Check for ammonia leaks. If the refrigerator is leaking ammonia, you will smell ammonia or see the appearance of yellow stains on or around the cooling unit. If this is the case, shut off all electricity and gas to your refrigerator immediately. You will need to replace the cooling unit entirely before operating this refrigerator again. Ammonia is flammable and presents a potential fire hazard.
