I run a small fan in my refer vent from solar. It is on during daylight and goes off when sun goes down. Never have to worry about it and it moves a good bit of air. Everything else is run from the on board batteries, which are charged with the roof panels.

Dan,
Where did you place that fan?
Why did you feel it should be added?
Thanks!

I also installed a small solar powered fan in the roof vent above the fridge. I got the kit, including a new vent cover, from my local RV supply. It is made by Camco:

At the suggestion of the mechanic that works at said local RV supply, I mounted it in the frame of the roof opening for the vent. I took a picture of it when I installed the 3-way fridge last year. It is not a very good pic. Overexposed, but if you turn your screen just right, you can see it:

The RV mechanic said the fan would work best in that location and draw the most air over the coils. I like to think it works well. Anyway, it can't hurt except for my wallet.

So the idea is to add cooling and thereby
reducing the energy the fridge needs to do it job,
is that correct?

Somewhere I remember reading that you really should only have a small ( 1 inch or so) space behind the cooling coils so a good air flow will help remove the heat from the coils. Fans certainly will provide the same function, but I wonder if anyone has actually blocked the area behing the fridge to decrease the space and increase the efficiency that way?

So, did you notice a difference before and after the fan?

The idea is to increase airflow over the coils on the back of the fridge. The fan draws air up from the sidewall vent, across the fins and out the top vent.
In my case, I was doing a new install, converting from the original AC/DC Norcold to a three way Norcold. I built a baffle in the back of the compartment so that there is less than i/2" clearance to the fins on the condenser(?)coil.
The power for the fan, like Dan's, is free. I have no idea if it really makes a difference, since I did not have a heat absorption refrigerator before doing this. I do know that the new fridge works VERY well. The freezer will freeze water bottles and ice cube trays overnight or less.
