I checked the fan before modifying it to be sure it worked. I doubt it would be returnable once I got through drilling holes in it. The fan is $15 (shipping included) from ebay and modification is a cheap risk. As far as the fridge itself, there's no real installation other than attaching an alligator clip to the cooling fins and attaching a wire to a 12v source.

I believe the fellow that sells the product buys computer fans in bulk and adapts them for use in an RV. Probably not cost effective for him to put a molded screen on every one. And the fridge manufacturer will never do it for cost reasons (not good reasons, just cost reasons). The screen cost almost as much as the fan but for me it was a surplus item that I had used for its original purpose for six years before recycling it for this use.

If you are going to buy 12V computer fans, it would probably be best to buy ones with 2 ball bearings instead of bronze sleeves. The ball bearings should handle the cold better and will be quieter. You also want to compare CFM. Many of the same diameter fans will have very large differences in the amount of air they push.

Newegg is a good place to compare:

Newegg.com - Computer Case Fans

Just need to know what size you want. A 120mm fan is about 4 3/4 inches. You can also get the fan grill, too.

I bought a box of "Computer" type fans for 10 bucks, (I think it was 12 vans) and used one of them. Got the 12 volts from the bright idea (light bulb) just hoked up before the switch.

Actually, my concern is about the REFRIGERATOR warranty. I'm not worried about a $15 fan. LOL!!!

I tried to cover both bases. There is no real modification to the fridge.

I too bought 2 of the blue eBay fans and installed them on top of the fridge fins blowing downwards. Takes up no extra space in the fridge and I can now cool the fridge on the 2nd warmest setting even during the summer months.

Try fan outside

What is more effective in improving the fridge efficiency is to install a fan in the outside compartment. This is where the heat needs to be dissipated. Place the fan so that it will exhaust air through the upper vent. That will assist the normal upward convection.

On mine, I also have it switched by a normal household heating/cooling thermostat inside the compartment. I keep it set to turn the fan off when the temp. in the compartment drops below 75 deg.

I have never seen this type of fan install before. Dometic and norcold make fan that clip on the rear of the fridge on the pipes if the inside of your fridge is freezing its a good chance that the air flow on the rear isent good enough. Fridges are very touching and most fridges are not installed properly from factory. This appears to just be a quick fix to hide a problem that still exists.
