Allow the refrigerator to operate for up to eight hours with an RV refrigerator thermometer inside the unit. The refrigerator needs to operate for six to eight hours before it will be cool. The thermometer will help you know what the temperature is inside the refrigerator. Avoid frequent opening and closing of the doors for several hours.
Open the refrigerator door and smell inside the refrigerator. A strong ammonia smell may mean that the coils need servicing. This is outside the scope of most RV owners, and the coils should be serviced by a professional.
Ensure that food is not packed in tight, which does not allow the air to circulate properly. If you are running the refrigerator on electricity, switch the refrigerator to the liquified petroleum gas operation. Most often on hot days, the LP gas operation will cool the refrigerator quicker than the electrical operation alone.
Purchase a small battery-operated RV refrigerator fan and set it up inside the lower part of the refrigerator. Point the fan upward to help the refrigerator to draw out air more quickly.
Inspect the upper and lower vents on the RV to ensure they are free of spider webs, nests and debris. The air must circulate away from the refrigerator and out of these vents. When the vents are blocked, the air cannot escape.
