RV REFRIGERATOR TIPS & TRICKS

For the most part RV refrigerators are efficient, but sometimes RV owners do things that result in the refrigerator being less efficient. Today I want to discuss some tips and tricks that will help your RV refrigerator operate at maximum efficiency.

1) First and foremost the RV must be fairly level for the refrigerator to operate properly. Older RV refrigerators required more precise leveling, but even newer models need to be close to level for optimum performance. Over time a cooling unit operated out of level can be permanently damaged. When you set up at the campground you can use a carpenter’s level to ensure the RV is close to level front-to-rear and side-to-side. It doesn’t need to be perfect, but close.

2) The initial cool down process can take four to six hours. I recommend turning the refrigerator on the day before you plan to leave for a trip, and before you put any food in it. When you do put food in the refrigerator it should already be cold, and food put in the freezer should already be frozen. Adding already cold food, rather than warm food, lets the refrigerator work more efficiently. One common mistake people make is to over-pack the refrigerator. There needs to be space between the foods for air to circulate throughout the refrigerator compartment. In most situations you will have access to a store where you can buy food, so a two to three day supply should be enough.

3) To assist with air circulation you can purchase an inexpensive battery operated refrigerator fan. Install the batteries in the fan and place the fan in the front refrigerator compartment blowing upwards. The fan will improve the refrigerator’s efficiency by circulating the air and it helps reduce the initial cool down time by 50 percent.

4) The heat created by the cooling process is vented behind the refrigerator. Air enters through the outside refrigerator vent and helps draft the hot air up and out through the roof vent. Periodically inspect the back of the refrigerator and the roof vent for any obstructions like bird nests, leaves or other debris that might prevent the excess heat from escaping.

5) Another good idea is to install a 12-volt, thermostatically controlled refrigerator vent fan at the back of the refrigerator, or at the top of the roof vent. The fan will assist in drafting the hot air away from the refrigerator. If you are mechanically inclined, these fans are fairly simple to install, or you can have your RV dealer install one for you. Either way it’s worth it. The fan removes the heat from behind the refrigerator, improving the refrigerators performance by up to 40 percent. Note: Some new RVs come with a fan already installed.

6) The outside temperature also affects the operation and efficiency of your RV refrigerator. When it’s cold outside you might need to lower the temperature setting and when it’s hot outside you might need to raise the setting. Extremely hot weather will directly affect the refrigerator’s efficiency. When it’s really hot outside try parking the RV in the shade, especially the side the refrigerator is on. Note: Some RV refrigerators are preset by the manufacturer and you cannot manually adjust the temperature.

7) Last but certainly not least you should always keep a thermometer in the food compartment. Food can begin to spoil at temperatures above 40 degrees. A small thermometer will let you know at a glance if your RV is operating efficiently.

RV refrigerators will operate very efficiently if we apply these simple tips & tricks to help make the refrigerator’s job easier and less demanding.
