how we got better air circulation and even temp in the frdge

as others have suggested, we added low speed PC style muffin fans in front of the fridge cooling fins.

they make no noise yet do an EXCELLENT job of circulating cool air. better yet , the fridge cools faster

Looks great. Why only one fan guard?

Where did you get the voltage from? The inside light or some other place.

Do the fans have any effect on how often you have to defrost?

i run a small gauge wire through the fridge door. its small so no air leakage

so far , no issue with defrost. but if its very humid outside, the frost could build up faster.
frost is less likely as the air is always moving

Good job if not a bit overkill.

Circulation doesn't require huge airflow. 1 low speed fan would be more than enough.

As for power, people have snaked a small gauge wire down the drain pipe. There is a 12V source right the behind the fridge.

we need to do that, would you post specifics for what/where to purchase the fan and location for the 12V source behind the fridge

Thanks in advance

Most of the commercial products blow rearward over the fins.

Think gentle air circulation. Not cooling. The fans don't "cool" anything. Just aids the natural convection currents that happen in a refrigerator without any fan. There's probably no right or wrong flow direction.

Camco sells battery operated toy like fans for pennies. These run on batteries for ~10 days at a time. Anything more uses unnecessary power draw and to some extent, heat (from fan motors).
