How to Identify the Problem

When you take out food from your fridge and find it to be warm, you may suspect a potential problem. But you cannot possibly identify the problem right away. You will have to confirm whether the dometic refrigerator is not cooling. This might be the case but it can be some other problem too.

The First Way

If the RV refrigerator is not cooling, the first thing you should go find is a thermometer. You will have to place it inside the refrigerator for a couple of hours. When you take it out, you need to cross-check it with the current temperature setting of the fridge not cooling but the freezer works.

If the temperature of the thermometer is much higher than that of the RV fridge freezer that is cold but the fridge is not, there is a problem! You must be wondering why the thermometer needs to be placed inside for so long. Well, that is in order to avoid any human or thermometer errors. So that the thermometer can meaure the temperature a couple of times.

Make sure to use a refrigerator thermometer. It is not the same as a regular thermometer, so be wary of that!

The Second Way

Another way to confirm if the dometic RV refrigerator is not cooling but the freezer works is to find the coils. Yes, that is right! The coils inside both, the fridge and the freezer. If there is a huge difference between the temperature of both of these, the issue will be confirmed.

Be sure to be cautious, though. The coils might be too hot if, in fact, the Rv refrigerator is not cooling but the freezer is. Make sure that there are no children around and that your hands are protected.

The Third Way

This method will only work if your freezer works but the refrigerator doesn’t that has a gas mode. If there is a gas mode then the refrigerator must have a flame behind it. All you need to do is to check if it is burning properly or not.

Once again, you need to be cautious regarding your surroundings. Make sure no children are near you. They should not know how to approach this burning flame. Moreover, be careful to stand at a distance from the place of the burning flame. You just need to observe whether it is burning properly. You do not need to approach it or touch it.

To be Noted: In recreational vehicles, the freezer always cools before the refrigerator. This means that if the dometic refrigerator is not cooling but the freezer is, the issue is with the airflow.

The second probability is that there is a diffuser installed. The diffuser moves cool air from the fridge to the freezer. If maintenance is low, then the diffuser must be clogged. 

The reason for the above-given factors is most likely to be that you have driven your RV on bumpy roads excessively. Yes, RVs are built to endure bumpy roads. But excessive bumps still cause this issue.

What You Should Really be Looking for

However, before you take any of the steps mentioned above, there is an important piece of information to know. That is, that if the refrigerator won’t get cold but the freezer will, by how much must the fridge’s temperature be off? As in, what is the optimum temperature of the fridge and freezer be?

Do not take this as the information to be used when looking at a regular fridge and freezer. This is because an RV fridge and freezer work differently. So, in the case of an RV food cooling system, the freezer’s temperature should ideally be 0 degrees. And that of the refrigerator should be somewhere around 34 degrees.

Common Reasons if Dometic Refrigerator not Cooling but Freezer is

Although we touched upon this in the note given above, there are several other potential reasons too. You need to know all the possible reasons behind your RV refrigerator and freezer not cooling or just your dometic refrigerator not cooling. Be sure to check out our list given below. This will make it easier for you to handle the situation if the refrigerator is not cooling but the freezer is fine.

The Thermistor

The thermistor an essential part of the RV’s refrigerator because it is what controls the cooling cycle. Not only of the refrigerator but of the entire RV. If the temperature outside the RV is too high, the power of the thermistor is compromised.

Meaning to say, if the temperature of the area where you are driving your RV or where you have parked is hot, the thermistor will cease to function properly.

The cooling cycle gets caught up with the heat. This causes the fridge to not be cooling but the freezer works, still. The simplest solution to this issue is to replace the thermistor with a new one. It will not probably be too costly, so it is a reasonable way to go.

Also, do not let the refrigerator run without a thermistor for too long. If your refrigerator not cooling but the freezer is fine, leaving it without a thermistor will cause even more detrimental issues.

The Exhaust

The purpose of the exhaust is to let the built-up heat in the refrigerator be let out. If the exhaust doesnot do its job properly, then the heat will build up inside the refrigerator. And this will eventually lead to the dometic refrigerator not working but the freezer working.

The reason behind the exhaust of the refrigerator failing to do its job is usually the same as any other regular exhaust. And that is, yes you guessed it right, the exhaust being too dirty. It is filled with dust particles and other harmful elements. Only because of lack of maintenance and care.

So, the solution to this issue is just that simple. Keep your RV clean! We assure you, that in doing so, you will not only solve the problem if the dometic RV refrigerator is not cooling but the freezer is but many other problems too. Maybe even problems you may not be aware of existing too!

The exhaust can be cleaned by removing the vent cover. This will probably be located at the top of the RV’s roof. Then you can start your cleaning from there.
