So, if the check light came on when you are using electricity or the automatic setting, it means both the electricity and gas systems might have a problem. In this situation, your fridge won’t cool down properly.

  • Sometimes, the issue might be simple, like forgetting or not plugging into shore power.
  • There can also be an issue with the fridge’s heating element. Some heating elements such as water heaters last a long time, but others can stop working within 2 years.

Understanding and Fixing a Blinking Fridge Check Light

When your RV fridge is set to use electricity, you should not often see the check light blinking. If it does, don’t worry; you can switch to the auto light or AC power settings to turn it off, and your fridge should get back to working normally.

However, when the fridge is set to auto and you notice the light blinking, there might be a problem with either the lower control board or the upper controls.

  • You can do a simple check using a volt meter to see if your power source is providing unstable electricity, which the control panel doesn’t like.
  • If you find that the electricity isn’t the issue, it’s a good idea to call a professional repair person. They can inspect your fridge and determine if one or both of those parts (the lower control board or the upper controls) are faulty and need to be replaced.

Common Reasons and Quick Fixes For Continuos Check Light

After going through the basic details about the RV fridge light blinking, let’s learn about the culprits behind the continuous check light.

6 Reasons for Continuos Check Light:
  • Poor Ventilation: Modern Dometic model fridges need proper airflow. Keep your fridge away from walls and remove any obstructions around it.
  • Damaged or soiled seals: Fridge seals can loose power and their integrity, so keep them clean. Debris can prevent the door from sealing tightly and allow warm air inside.
  • Dirty Evaporator Coils: Regularly check and clean these coils as they can get dirty over time.
  • Soiled Condenser Coils: Clean these coils when you clean the evaporator coils. They can accumulate dirt too.
  • Thermostat Settings: Ensure the thermostat is set to the correct temperature and check if the gas valve is open.
  • Igniter Issues: If the igniter isn’t working, you might need to replace it.

If none of these solutions work, it’s possible that your fridge or some of its parts are defective, and you’ll need a professional technician to assist you.

3 Tips to Maintain Your RV Fridge for Optimal Performance

Maintaining your RV refrigerator is essential to ensure it continues to work properly and keeps your items cool during your travels. Below, I have outlined some detailed tips and practices to help you maintain your RV fridge in optimal condition.

1. Leveling Your RV: Keeping Your Fridge in Balance

To keep your RV refrigerator functioning as it should, maintaining a level position is necessary. While the fridge doesn’t need to be perfectly level, staying within about 3 degrees of level is recommended to avoid potential issues.

However, being level is not just about the fridge; it is also important for the overall stability and comfort of your RV. It ensures that the cooling unit in your fridge operates effectively and prevents potential damage.

2. A Clean Flue for a Reliable RV Fridge

Regularly cleaning the flue and burner tube of your RV refrigerator is a necessary maintenance task. Even if your fridge seems to be working fine, keeping these components clean can significantly reduce the odds of experiencing burner-related problems.

Cleaning the flue and burner tube helps maintain proper gas flow and combustion, which is essential for efficient cooling.

3. Enhancing Airflow for a Cooler RV Fridge

Adequate airflow around the refrigerator’s vents is essential for its proper operation. Also, make sure there are no obstructions around the vent located at the top and back of the refrigerator. If your RV fridge is equipped with a vent fan, make sure it’s in good working condition.

If your fridge doesn’t have a fan, consider installing one. A vent fan helps maintain consistent airflow, reducing the workload on your fridge and promoting smoother and more efficient operation.
