RV refrigerators don't use a compressor instead using heat, either from an electric heating element or an LP-gas flame. The heat starts a chemical reaction, and evaporation and condensation cause the refrigerator to cool.
The heat created by the cooling process circulates within a narrow space behind the refrigerator. Air enters through the lower access panel and moves the hot air out through the upper access panel or roof vent. The dead air space directly behind the refrigerator is drastically reducing the efficiency of the fridge!
Here is the solution: The best way to increase the cooling efficiency of your refrigerator is to increase the airflow on the back of the fridge. You need to install two 12-Volt DC circulation fans at the back-end of the refrigerator and a thermostat to switch the fans ON when the heat rises.
Where should I install the two fans?
You could install both fans behind the lower vent or the upper vent. Also, you may install one fan on each the upper and lower vent
If your RV has a top vent on the roof, install both fans behind the lower vent.
This kit will lower the temperatures inside the refrigerator, decrease the time to reach the desired temperature and boosts the performance by up to 40%.
Our setup will remove the heat from the back of your fridge (not just spinning the already hot air around...)! You could install both fans behind the top vent to blow the hot air outside. Alternatively, you could mount both fans behind the bottom vent to pull fresh air inside; this is an excellent solution if you have a top-vent on the roof! Moreover, you could install one fan on top and the other on the bottom vent, another excellent method to increase the efficiency of your fridge.
Note: With our setup - you don't need to pull the fridge out for the fan installation, just open the access panel on the outside of your RV...
