Adding cooling fan to refrigerator?

I installed six small used computer fans on the inside of the lower intake vent cover, using plastic zip ties. I wired all of the fans to one switch and power is from the 12 volt supply at the back of the frig. The six fans force cooling air up thru the back of the frig and out the top. The frig is much more efficient with this arrangement. I also installed a 5 inch fan inside the box to keep frost from forming on the cooling coils, and it also works well.

My refrig. tended in the mid-40's. A little scary. I got an inside portable refrig. fan from Tweety's that runs on two 'D' size batteries. Instructions said it would run for a month on the batteries. I doubted it, but in fact, it does.

Anyway, back to the topic: it reduced the temperature about 10 or more degrees, despite backing off one position on the temp. switch on the front of the refrigerator. And the temps are much more consistent, so no freezing things at the back while things in the door pockets are too warm. Like milk.

This might fix your problem, and for just under $20, you aren't risking much. Camping World has them, too, 'on sale' for about $16. Called a Frig Airator or some such.

When it gets to be 90 or above the frig is at 42 to 46. I know the side vent VS the tov vent don't vent as well. I thought about making a bracket that will hold the fan so it just touches the top vent cover when in place so it will push out as much air as possible. By running the two factory fans all the time it would make the frig work less and cool better.

yes you can add the vent fan yes it will help

while you have the vent cover off,
check for the flashing/block that will force the air out the vent instead of letting it be trapped above the fridge

Installing optional (extra) cooling for camping within extreme hot temps is a good idea. Especially since most RVs are factory built for "average" temp ranges. If extreme hot temps, installing "more / extra" air flow cooling for the external fridge is a great idea.

If wondering, I installed a 12V computer fan with manual off/on switch (with inline fuse) on my TT as well. For it, I simply plastic pull-tied the compuer an to its rear cooling coil. On extreme hot temp days, I turn this 12V fan ON. One can also install a 12V fan within its roof top venting lid (at top of its vertical flu) on a 12V manual switch as well. Note: I have it on manual off/on switch to turn off at night - to allow the over sensitive ears on my wife to sleep at night. LOL!!!

Another idea is to buy "store bought" and simply bolt it on. I hear store bought fan systems (12V rear cooling &/or solar power for roof top) work great as well. For more detals, surf: - Click Here -

IMO, additonal cooling (on its rear coils and vertical flu) should be factory build. After this simply DIY mod, my RV's fridge now runs less often during extreme hot temps - because it's now getting extra cooling during those extreme hot days. For my TT, this MOD was well worth it....

You should look at this venting information. Refer vents on slideouts don't work as well as on non-slideouts. I would check to insure there is no void on top of the refer. They rig's manufacturer should have use some metal flashing type material to route the air coming up through the coils to ward the upper vent outlet. They should have installed blocking material so the air from the bottom vent is routed through the coils with only a small amount of clearance toward the exterior wall of the rig.

Our Norcold 6 cu ft reefer now has 3 computer fans that I installed at the top of the stack.
Running off the solar panel output with a separate switch.
Runs good and pulls the heat up and out and is quiet.
