Being the cheapskate I am, I don't use power unless needed. Is there a humidity number when to fire the muffins? The humidity here is at 13%, so not to use the fan, I assume?
If you are talking about inside the frig, I run mine all the time to get nice even cooling. The frig probably then uses less energy than the fan requires.

If you are talking about the fans at the top of the outside access area, TEMPERATURE is the determinant. If that side is in the sun and/or temperatures are over, say 90 degrees, the fans will materially enhance refrigerator cooling performance.
And, those small muffin fans use very little power.
In the combustion area of the fridge outside access door, where is the best location to install a fan?
If I ever find out where our's is, I'll let you know, Peter. Must be in the upper area, can hear it working, there is a switch above the sink area that is marked as such. If it ever fails, looks like the fridge will have to be removed. Perchance, Papa Brett remembers? ^.^d
Ours is at the top of the air column behind the fridge. Actually two of them that run as needed: one or both.
Larry, are the fans on a thermostat?
I would assume they are since they don't run every time the fridge does.

Yes, the proper location for the muffin fans is at the top of the refrigerator outside area, exhausting up. And that is where yours are, Mike.
To install or service, do NOT pull the refrigerator (unless you are into extra weight training).
You can access them from the roof by removing the refrigerator roof vent. You will need to carefully loosen the screening or just replace it (bed it in black RTV is pretty simple).
You only need to reach down a foot or so to access the fans.
