Keep the RV level at all times when using the fridge at the camping and parking zone. When the RV is at rest, the cooling fluids and gases stay in a static position. If the RV is not level, it causes the fridge to lose efficiency over time.
Anticipate when you need the fridge cold and working. Most RV fridges need at least a four- to six-hour cooling period when you first turn them on. As a general rule, turn on the fridge the night before your trip. When you turn the unit on, clean out the heat vents behind the fridge on the outside of the RV. If clogged, the fridge will not run cold.
Power the fridge via electricity when camping in campgrounds or areas with hookups. Use the propane connections (if your fridge is dual powered as many modern RV fridges are) when camping off the grid.
Calibrate your fridge's internal temperature based on the outside temperatures. For example, if the outside temperature is 90 degrees, turn up the cold setting inside the fridge. If the outside temps are colder, turn the cold setting down. An RV fridge is affected by outside air temps.
