Back when I first started our parade of cooling units, I installed a muffin fan at the base of the fridge scoop, set to blow upward into the scoop. On hot days, I turn the fan on. It pulls the warm air out of the compartment, and out the vent like should happen naturally, but doesn't. This has resulted in a 5 degree or more drop in temp in the fridge. That, along with sealing up the base of the fridge vent scoop, and the joint between the interior walls and bulkheads, has resulted in a fridge that will consistently freeze almost anything put in it, with an ambient outdoor temp of anything less than 95. This after several cooling units, and a third new fridge.
