Internal Fridge Fan

NWJeeper · 07-12-2010, 11:44 PM

Because of my recent issues with our 4-door RM1350 fridge I have made some recommended venting modifications including adding a fan to the roof vent to help with the venting airflow.

My next step was to add an internal fan. I looked at a couple of the cube fans that run on batteries available though Camping World and other outlets. However after reading the reviews I found that most buyers were not all that impressed with them and they use 2 D-cell batteries about once a month. One of the reviewers had a link to a fan from a seller on Ebay so I checked it out.

At only $14.99 this dual axial fan unit gets it's power from the internal light in the fridge which has +12volts continuous all the time (the door switch interrupts the ground to the bulb) It gets it's ground from the cooling fins in at the back of the fridge by simply clipping an alligator clip to them.

After installation I recorded the internal fridge temperature at 51 degrees. Ambient air temp inside and outside the RV was 71. After running for 1 hour the fridge temperature was down to 38 degrees! I was floored. I have seen fridges take many hours to cool this much!

Even if you aren't having issues with your fridge but are heading for hot temperatures on your next camping trip I highly recommend this fan.

The seller on Ebay is: rflkt1
He shipped lightning fast. I ordered the fan on Friday and received it on Monday.

Does it make much noise? I was thinking of doing something similar with some quiet Scythe computer fans I use in the rear fridge stack but why reinvent the wheel.

No Ron, not much noise at all, you can just barely hear them with the door closed. The fans are small only about 1.5" or 2" square. Honestly I don't think you could buy these little fans for much less than what he is asking for these. He sells lots of them too. Although I have never heard the cube ones you get at RV suppliers I imagine that these are probably just as quiet if not more so.

Don't know why the frige manufacturers don't put something like that in from the get go!!
Would probably solve a lot of problems.

I was thinking the exact same thing. If this guy can make and sell these things for $15 and make money then you would think the cost would be minimal to a huge manufacturer to incorporate them into their products. It's been proven for many years that a small fan circulating the air in a fridge makes it much more efficient. Common Dometic and Norcold get with it.

NWJeeper,
I just ordered the fan that you detailed in your post today. Did you say that you received your fan in a few days? Can you tell me where was it shipped from? I just ordered one and they say that delivery time is 12-15 days. Did it say that when you ordered yours? I am on the east coast so that my be a factor.
thanks for the info on this fan.
Tom

Now you know what this means. You've got me spending money now! It's not suppose to be this way!

Thanks for the info.

I'm ordering mine today.
