i have a 2005 aliner i took the back 2 vent outside off behind the refrigerator one vented and one not,now i dont remember which goes on top and which goes on the bottom can anyone help?thanks-mike
My 2004 fridge vents are identical top & bottom, so they can be interchanged. The point of the vents is to allow airflow from bottom to top to expel the heat generated by the refrigeration system.
I added screen to the inside of my vents to keep the critters from building nests and webs inside. The screen reduces airflow so when it is really hot outside I remove the vents while camping to increase efficiency. Many people have added electric fans to increase airflow.
