![]() ![]() Before we get into listing those suspects, you need a couple of words of advice.įirst, make sure you have the right tools on hand to find and handle the problem. If your freezer is cooling and your fridge is not, you need to check the usual suspects first to make sure they are all operating correctly. The process of cooling your fridge section starts with your freezer and moves down, following the gravity system. There are some usual suspects when you go to diagnosis what why your fridge is not cooling when your freezer is. ![]() The only thing wrong is that you have not let enough time pass to let the fridge get up to speed. If you check back before that time, say after only a few hours, you may think something is wrong with the fridge. What that means is you have to turn the fridge on about 24 hours ahead of the time you are going to use it. Now the problem with this system is that it takes time to work. ![]() This is the basic version of how the majority of RV fridges work. Then after it has done that job the ammonia liquid is sent to the boiling section to be turned back into gas and to start the process all over again Then gravity moves the ammonia liquid to where the hydrogen gas removes the heat in the ammonia.Īs the cooling ammonia evaporates, it cools your fridge and freezer unit. The cooling system turns the ammonia gas into a liquid and the more you have the better. The two main gases used in an RV Fridge are ammonia and hydrogen. This allows the cooling unit to move the different gases throughout the cooling system. They only have one to cool both the fridge and the freezer.įor the refrigerator to work properly, you need to have your RV level when not driving it down the road. We have mentioned that the majority of RV fridges are gas absorption models and that they do not have two separate cooling systems. You may have to check them one at a time to make sure you find the right source for your problem. As with the Norcold, the Dometic fridge has many components that influence the cooling power of your fridge. Follow the same instructions found in the Norcold and you should be able to see if the thermistor is defective or not. Finally, you will need to check the thermistor. Keeping your outside access and interior passageways clear supports your refrigerator’s work. These elements work hard to stop your fridge from operating normally. The outside vent may not stop all these things or even insects and small animals from getting inside. Next, you will have to check for dirt, debris, and blockage. Once the temperature gets over 90 degrees F, the fridge may not cool like it should. ![]() Then if you are camping out or in an RV park in very hot geographical regions of the country, then you are going to have problems with your fridge. Your fridge depends on your rig being level at all times when it is parked, even when it is in storage. You may think that leveling your RV is only good for the frame and slide outs. If your RV is not level when parked, then you will have trouble with cooling your fridge. That means the problems you had when you owned the Norcold will be the problems you are having with your Dometic refrigerator. Dometic Refrigerator Not Cooling But Freezer Worksĭometic also uses the gas absorption and gravity system as Norcold does. To find the problem may take a little time as you have to check each part till you find the defective one. The reason you may be having a problem with your Norcold RV Fridge is that it is a gas absorption model and it has too many parts that affect the cooling system. If your fridge cools like normal, then you have a bad thermistor on your hands. If your fridge is not showing any error codes, lower the temperature setting to as low as it will go. If you have done all that, there is still one more step to take. Bad airflow means that the fridge components will not get the air they need to keep the fridge nice and cool. Remove the access panel and clear away any debris around the cooling fins and the outside vent. The break point temperature for this scenario is 90 degrees F.Īlso, you have to make sure the cooling fins have proper airflow. The next thing you should be aware of is that if the outside temperature is too hot, then the Norcold fridge will not work right. Their cooling system works by gravity and keeping them level helps the unit distribute the coolant to where it needs to go. One of the first things you need to know about Norcold fridge and freezer units is that they must be level to work properly. ![]()
