Ventilation – Exterior vents should not be obstructed – Interior fans should run smoothly
Model Specs – Model number – Manual with temps info – Recommended temperature range
Controls – Thermostat dial – Mode button – Temperature display – On/Off switch
Sizing – Storage capacity – Dimensions
Usage Factors – Frequency of opening door – Full vs. empty – Ambient temperatures
Temperature – Optimal range 32°F – 40°F – Colder for dairy – Warmer for produce

Take some time to know your refrigerator. Understanding how it operates will make adjusting and optimizing temperature much simpler.

Using Your Dometic’s Temperature Controls

The key to changing the interior temperature is mastering your Dometic’s temperature controls. Here’s a breakdown of how they work:

Here is a table explaining the main temperature controls on a Dometic RV refrigerator:

Control Function Notes
Thermostat Dial Increases/decreases interior temperature Temperature scale varies by model
Mode Button Switches between power modes: Auto, Gas, Electric Select mode based on power source available
Temperature Display LCD shows interior temp on some models Use to monitor temp when adjusting thermostat
On/Off Switch Turns refrigerator power on/off Off position doesn’t fully stop cooling

Getting to know your refrigerator’s controls prepares you to start adjusting the temperature dial.

Determining the Ideal Temperature Setting

Dometic refrigerators are designed to maintain temperatures between 32 and 40 degrees Fahrenheit (0 to 4.4 degrees Celsius). But what’s the best temp for your needs? Considerations include:

  • Food storage – Milk products and meats require colder settings around 37°F while produce lasts at higher temps around 40°F.
  • Usage – Opening the door frequently or having a full vs. empty fridge affects temperature regulation. Maintain a higher setting if heavily used.
  • External factors – Ambient outdoor temperatures impact cooling performance, especially in hot climates. You may need to adjust the thermostat lower to compensate.
  • Personal preference – Some users like ice-cold temps while others don’t require maximum chilling. Decide on your ideal temperature.

Take these factors into account when choosing the right thermostat setting for your fridge contents and needs.

Adjusting the Temperature Up or Down

Once you’ve decided on your target temperature, it’s time to actually adjust the dial. Just a few pointers:

  • Make small thermostat adjustments incrementally. Change the dial 1-2 numbers at a time.
  • Allow several hours for the interior temperature to stabilize before assessing if further changes are needed.
  • If foods are too warm, lower the thermostat and vice versa to raise temps if contents are freezing.
  • Refer to your Dometic’s manual for the recommended temperature range for your specific model.

With some minor trial and error, you’ll find the dial sweet spot that keeps your refrigerator at your desired chilling temperature.

Verifying Results with a Fridge Thermometer

How do you know if those thermostat tweaks actually aligned the temperature with your target? Using an independent thermometer is the best way to verify.

  • Place a freestanding fridge thermometer inside to monitor the interior temperature.
  • Check the thermometer reading after adjusting the thermostat and allowing time for the change to take effect.
  • Make additional small thermostat adjustments as needed until the fridge thermometer displays your ideal temp.

Having an accurate temperature reading ensures your Dometic is chilling properly. Portable fridge thermometers provide assurance your settings match your desired cooling level.

Maintaining Proper Temperature When Parked

Once you’ve dialed in the optimal temperature, a few maintenance steps will keep your Dometic running efficiently when parked:

  • Keep vents unobstructed – Ensure exterior fridge vents have open airspace so ventilation flows freely.
  • Use proper leveling – Park on an even surface and use RV levelers to prevent compressor issues from tilting.
  • Close door tightly – Make sure the door seals and latches closed so cooled air doesn’t escape.
  • Defrost regularly – Built up ice decreases cooling performance so defrost as needed.

With consistent care and attention, your Dometic can maintain steady temperatures throughout your RVing adventures.

Troubleshooting Common Dometic Temperature Problems

If your refrigerator is having issues maintaining proper temperature, a few quick troubleshooting tips cover common problems:

Symptom: Fridge not cold enough

Solution: Make sure fridge is level, verify vents are clear, lower thermostat setting, and check door seal and closure.

Symptom: Foods freezing

Solution: Raise thermostat to warmer setting, use fridge thermometer to verify actual temp, and reduce loading capacity if overfilled.

Symptom: Temperature fluctuating

Solution: Confirm ventilation is unobstructed, check exterior temps are within operating limits, verify fridge is on proper energy source setting, and make sure contents are loaded evenly.

With some adjustments and maintenance, you can get your Dometic back to cooling properly. But for any persistent temperature regulation issues, always consult authorized Dometic RV refrigerator repair professionals. Proper repairs will have your fridge chilling optimally again in no time.

Cruise Comfortably With an Ice-Cold Fridge

Don’t sweat your refrigerator temperature settings. While RV appliances like the Dometic have their own unique operations, a bit of knowledge about maximizing and monitoring temperature goes a long way. Adjust the thermostat dial gradually, use a fridge thermometer to verify interior coldness, and keep your rig level and vents unblocked. Stick to the manufacturer’s recommended temperature range for your model. With a perfectly chilled refrigerator, you can relax and enjoy journeys to spectacular destinations in your RV.


How do I know what temperature setting to use on my Dometic refrigerator?

Check your owner’s manual for the recommended temperature range for your specific model. Most Dometic fridges maintain proper food storage temperatures between 32-40°F. Adjust in small increments towards the cooler or warmer end of that range based on your needs.

How long does it take for a new temperature setting to take effect in my RV refrigerator?

It typically takes 2-4 hours for a temperature change to fully stabilize across the entire interior of the fridge. Let the fridge run for several hours before checking if further adjustment is needed.

Why does the temperature inside my Dometic fridge fluctuate so much?

Frequent opening of the door, outside ambient temperatures, operating off different power sources, and improper ventilation can all cause temperature fluctuations. Allow extra time for temperatures to restabilize after changes.

My refrigerator is not getting cold enough. How can I make it colder?

First, check that ventilation is not obstructed. Lower the thermostat dial 1-2 increments at a time and allow several hours for the change to take effect. Verify the temperature with a fridge thermometer.

The food in my RV fridge keeps freezing. What should I do?

Gently turn the temperature dial to a warmer setting. Also, make sure the refrigerator is not overpacked, as too much dense food can prevent air circulation and cooling.

How do I know when to defrost my Dometic refrigerator?

Excess frost buildup of 1/4-inch or more will decrease the fridge’s cooling performance. When this amount of frost is present, it’s time to manually defrost the unit.

What’s the best way to monitor the interior temperature of my RV refrigerator?

Use a digital refrigerator thermometer designed specifically for RV use. This will provide the most accurate temperature reading to determine if adjustment is needed.
