Hot weather can spell trouble for RV refrigerators. Summer is rapidly approaching and warmer temperatures are already giving RV refrigerators a workout. Here are some recommendations to help you get the most out of this important RV appliance.
For starters, give the frig some shade. If your RV awning covers the side of the RV where your refrigerator is located, you're in luck. Make sure the awning is deployed during the time the sun shines directly on the refrigerator side. If your refrigerator is on a different side than your awning, you can make your own temporary shade with a tarp.
Another tip is to blow out the back of the refrigerator cabinet with compressed air. This will remove cob webs, wasps nests, leaves, dust and any other debris that may have collected there during the year.You may want to consider installing a small fan to help ventilate the refrigerator compartment. Many folks install "muffin" fans used to cool computers. The fans help expel hot air while pulling cool air into the compartment. Your refrigerator will love you for this. I installed an external fan control switch so I didn't have to remove the vent cover every time I wanted to turn on the fan. These units are also available as a kit from your local RV store.Minimize the number of times you open the door. Don't just stand there with the door wide open scrounging for a snack. Think about what you want before you open the door and get it all at once.
Keeping your freezer defrosted is vital for optimum refrigerator performance. Ice build-up in the freezer compartment decreases the efficiency of your refrigerator and raises the temperature inside the refrigerator compartment. Another idea is to install a small battery operated fan inside the refrigerator. This will help circulate air and keep everything uniformly cold. If you stuff the middle shelf with containers and plastic bags, you essentially block the cold air from moving down to items on the lower shelves which may lead to food spoilage.
