How to defrost an RV fridge in 20 minutes

Defrosting an RV refrigerator is a simple task. It is recommended to defrost your RV fridge when the ice build-up is more than a quarter of an inch thick. Here is a step-by-step guide to defrosting your RV fridge in 20 minutes:

  • Turn off the refrigerator: Start by turning off your RV fridge. This is an important safety precaution.
  • Unload the freezer: Remove the contents of your freezer and place them into cooler bags or a cooler. If your RV is hot inside, consider covering the cooler bags with blankets for extra insulation. This step should take around 5 minutes.
  • Unload temperature-sensitive items from the fridge: Remove perishable items such as milk, yoghurt, lunch meats, and mayonnaise from the refrigerator and place them in an insulated cooler bag or a cooler. This step should only take a few minutes.
  • Use a hair dryer to thaw the freezer: Place an absorbent chamois towel in the bottom of the freezer compartment to absorb the melting ice. Then, use a hair dryer on a low to medium setting to thaw the walls of the freezer. Keep the hair dryer moving and maintain a distance of about 8 inches from the walls to avoid overheating. This step should take around 5 minutes.
  • Alternate between the freezer and fridge compartments: After thawing the freezer walls, move on to the cooling fins in the refrigerator compartment. Continue to alternate between the two compartments, being careful not to hold the hair dryer too close to the plastic walls or fins to avoid melting or cracking. This step should take around 5 minutes.
  • Remove the ice from the cooling fins: As the ice starts to melt, increase the distance between the hair dryer and the cooling fins. Do not use any tools to remove the ice, as this can damage the fins and cause refrigerant leaks. Simply allow the ice to fall off into the drip tray underneath. This step should take around 3 minutes.
  • Wipe down the fridge and freezer: Once all the ice has been removed, use the chamois towel to wipe down the interior of the fridge and freezer compartments. This step should only take a couple of minutes.
  • Reload the food and turn on the fridge: Put the food back into the refrigerator and freezer compartments, and turn the fridge back on. Set the temperature to the desired level, and allow it to cool down. This final step should take about 2 minutes.

By following these steps, you can efficiently defrost your RV fridge in 20 minutes or less. Remember to always exercise caution when using electrical appliances near water, and never leave your refrigerator door open for extended periods to prevent frost build-up.

Tips to prevent frost build-up in camper fridges

Frost build-up in a camper fridge is a common issue, especially if you are in a humid environment or if your fridge is exposed to direct sunlight. While some newer models have a self-defrosting feature, many camper fridges do not. Here are some tips to prevent frost build-up and keep your camper fridge running efficiently:

Maintain Good Air Circulation:

  • Avoid overstuffing your fridge with food, as this can hinder proper air circulation. Consider using an RV refrigerator airator fan to improve airflow.
  • Keep the door seals clean by wiping them down regularly. Ensure the seals are in good condition to maintain suction when the door is closed.

Monitor Temperature and Humidity:

  • Use refrigerator thermometers to monitor the temperatures in both the fridge and freezer compartments. This will help you identify any issues early on.
  • Try to maintain a consistent temperature in your camper. Frosting accelerates when the refrigerator is opened frequently, especially in a warm and humid environment.
  • If possible, avoid placing your camper fridge in direct sunlight, as this can contribute to higher temperatures and humidity levels.

Defrost Regularly and Properly:

  • Defrost your camper fridge at regular intervals, such as once a year or when ice layers become more than a quarter of an inch thick.
  • When defrosting, always unplug the fridge and remove all food items. Use insulated cooler bags or coolers to store temperature-sensitive items temporarily.
  • To speed up the defrosting process, use a hair dryer on a low setting, being careful not to damage the plastic components or crack the walls from rapid temperature changes. Alternatively, use pans of warm (not hot) water, a fan, or a wet/dry vacuum to accelerate defrosting.
  • After defrosting, ensure the refrigerator is completely dry before plugging it back in and turning it on.

Prevent Frost with Liners:

Consider using thin, flexible cutting boards or vinyl placemats as liners for your freezer walls, floor, and ceiling. When it's time to defrost, simply remove the liners, shake off the ice buildup, and replace them. This method can significantly reduce defrosting time.

Step-by-step guide to defrosting a camper fridge

Firstly, it is important to note that camper fridges should be defrosted approximately once a year or when the ice build-up becomes more than a quarter of an inch thick.

Step 1:

Turn off the refrigerator and empty the contents of the freezer into cooler bags or a cooler. If your RV is hot inside, consider covering the cooler bags with blankets for extra insulation.

Step 2:

Remove the most temperature-sensitive items from the refrigerator, such as milk, yoghurt, lunch meats, and mayonnaise, and place them into an insulated cooler bag or a cooler. Fruits, vegetables, bread, cheese, and condiments can remain in the fridge during the defrosting process.

Step 3:

Place a super-absorbent chamois towel in the bottom of the freezer compartment to absorb the water from the melting ice.

Step 4:

Use a hair dryer to thaw the walls of the freezer. Keep the hair dryer moving and maintain a distance of about 8 inches from the walls to avoid overheating and potential damage to the plastic walls.
