All about an RV refrigerator thermistor

Firstly, let’s take a glance at what a thermistor does in your fridge. What is its purpose and why is it needed? Also, we’ll look at when an adjustment is needed.

What does a thermistor do?

Now before we get into the adjustments needed for a Dometic RV refrigerator’s thermistor, let’s find out what a thermistor is and what it does.

You may have heard about it or you already have a vague idea. Nevertheless, let’s see what it’s all about.

A thermistor of a Dometic RV refrigerator is a clip-on device that is attached to one of the cooling fins of the fridge. The main purpose of this device is to convey the temperature inside the fridge box to the control board.

This is done so that the interior temperature of the fridge can be regulated and controlled. The position of the thermistor is shown in the user’s manual.

So it’s a good idea to familiarize yourself with it. Knowing where the thermistor is located in your Dometic RV refrigerator will make things a lot easier for you.

This way, you can easily make adjustments when your fridge malfunctions, instead of wasting time trying to find the thermistor.

When to adjust the thermistor?

So you’ve familiarized yourself with the thermistor and you know where it is located. But when do you know there’s a problem?

What are the alarm bells that you should look out for?

One of the first signs of a defective thermistor is your fridge not cooling properly. This can be discovered by observing water dripping out of your freezer.

If the ice inside your fridge is melting, this is a telltale sign that it’s not being cool enough.

Now the opposite could also happen. You may find out that your fridge is cooling way too much. You’ll notice ice forming in the fridge when this happens.

If you face such a problem, then the temperature needs to be adjusted to a warmer setting. This way, the ice formation will stop.

If you’re worried about calling in a professional to do this, fret not! Thermistor adjustment can be done at home easily! All you need is some patience and time in hand.

How to adjust the thermistor?

Now we know why a thermistor is important and when an adjustment may be needed.  So let’s take an in-depth look at the adjustment process of a thermistor.

Temperature Settings of a Dometic fridge

Unlike a regular fridge, there aren’t a lot of temperature settings in a Dometic fridge. In most of the cases, the number goes from 1 to 5.

But there’s a catch. When it comes to thermistor setting, always keep in mind that a higher number means a colder temperature.

This is the opposite of say, fixing your AC temperature. So 5 will be the coldest setting whereas 1 will be the warmest one.

Now the best temperature setting will differ from time to time, depending on the weather conditions you live in.

Most people claim that setting 4 works best for them. A good tip is to have your fridge loaded with food. The more food you have stored in your fridge, the more stable your inner temperature will be.

So don’t shy away from bringing your candy jar along with you on your camping trip!

The ideal temperature for an RV refrigerator

Now you may be wondering what the perfect temperature should be for your RV refrigerator.

There’s no rocket science here. The perfect temperature for your RV refrigerator should be between 40 to 42 degrees Fahrenheit. So if your fridge isn’t getting cold enough, try adjusting the Dometic refrigerator thermistor.

If it still doesn’t work, then there may be something wrong with your fridge. In that case, you might need to get it checked out.

Now even if this temperature is ideal, you may not always be able to achieve it with your fridge. For example, if you live in a really hot country, your Dometic fridge will have a harder time cooling.

Does that mean you need to take your fridge for servicing? Absolutely not.

There is still an acceptable temperature range that you can stay within. Moreover, if you set the temperature to a wrong setting, your fridge will take time to get adjusted once you correct it.

The upper limit

So don’t fret if the temperature is less or more than 40 or 42 degrees. Just remember that no matter what happens, your fridge should never get warmer than 50 degrees.

If you find this happening, know that there is a serious problem that needs to be fixed asap! If you store food at this temperature, it may become spoilt. Even if you don’t realize it, this food is unsafe for consumption.

If your fridge does get this warm, make sure you store your food in an alternative place and get it checked.

The lower limit

The lowest acceptable temperature for your fridge to have is 35 degrees. If your fridge starts getting cooler than this, then your food may start freezing.

This sudden change in temperature can also make your food go bad and toxic for your health.
