The fridge is too cold and freezes everything. Even though I set the temp control on 1 for the freezer and fridge, cold air comes out from the top-left compartment in fridge.
Even when I turned the fridge off (as in the attached pics) the cold air continued to come in from the top vent for about 30 minutes.
There was frost around the top-left vent.

Even when I turned the fridge off

You mean, even when you turn the fridge control to OFF, not turn the whole refrigerator off?

If so, there's only 2 possibilities I can think of. The pictured damper is not closing properly. That could be due to the actuating lever disconnected from the damper and not manipulating it to open or close it when the control is adjusted or a problem inside the damper itself, possibly requiring replacement of it.

The other possibility is maybe the freezer is way too cold. Measure the freezer temperature, it should be +5 to -2 deg. F. If the freezer is too cold even with the freezer control set to the warmest setting, the thermostat may be defective and need to be replaced. It is the freezer thermostat that controls the running of the compressor and the overall cooling of the appliance.

Check to make sure the damper linkage is connected to the damper and that the internal damper door opens and closes when it is actuated.
