jdc, the vent we're talking about is inside the fridge, not outside. There should be two air vents inside the fridge compartment. One of them has a fan that blows freezer air into the fridge. The other is simply a vent that allows air to flow back to the freezer. If one of them is blocked by food or ice/frost, or that fan isn't working, then the fridge won't get cold. A blockage could be due to food on top of a vent or ice due to failure of a defrost heater. The fan could either fail directly or the thermostat that turns it on could have gone kaput. There isn't much else to go wrong. Also, how is your freezer door seal. If it leaks then you can get excess frost in there which causes icing up (and costing you a ton of money in extra electricity bills).
