Default pics of my fridge mod

Hi guys, there was a gentleman here asking about the snyder upgrade kit for our rv fridges, I believe he doesnt sell them anymore, I looked all over, and decided to make my own, I bought 3 small computer fans, made a holding plate out of an old plastic tray (that my wife just cant seem to find anymore,,,)and mounted it just under the upper coils, I ran a 12v on/off switch, and mouted that near the fridge door.when I turn on the fans, they blow air over and through the coils, and it really has made a huge improvement, I am posting some pics, it will be much easier to see. My fridge is a dometic 2310, from a 97 roadtrek,, it cost me less than $20.,and took about 3hours to complete,,, I hope this will help someone else,,, if you hsve any questions, please le me know, thanks,,,,,

You're in trouble when she finds out or maybe her hero if the ice cream is still firm on a 100+ degree day!

We did a similar mod for our Dometic fridge in our 2004 Roadtrek 190v last year. Since I did not remove the fridge, there was limited space to install a fan.

I used a single 12v 1.68a fan from Princess Auto. It was pretty effective for moving the air out through the upper vents, but was noisy as heck and the draw on our batteries was significant, so we stopped using it.

Can you tell me the specs on the fans you have used?

most RV fridges are 3 way- ac/gas/12 volt dc.

so tap into the 12 volt DC power that is already back there ( manuals are available online for free download) use a fuse and a switch.

if you are going the wire up an internal fan- use a smaller quieter fan as you only need to circulate air inside the fridge- the wiring can be snaked down with the drain tube from inside the cabinet to the rear wiring.

BTW the fans I use ( above) have been durable and are fairly quiet-


I'd do some pics- but I am 5000 miles away from my van- working

I agree with MKguitar, I tapped into the 12v line that was powering the fridge, it was right at the bottom of the fridge and very easy to tap into. I picked up my fans from a computer surplus store, at about $4 each, they are 3-1/2 by 3-1/2 inches, and they are rated at only.13 A, they don't draw much power, and I really don't even hear them running at all, I installed the on/off switch so not to have them running all the time, I really only use them when starting up the fridge, , or when I'm driving down the road and the fridge is on 12v and on hot days when the sun is on the van, turn them off at night and on cool days when it isn't necessary to have them running. hope this helps, please if you have any other questions, I will try my best to help,,,,thanks,,,,.

You can get these really nice little controllers on eBay or Amazon that modulate the fan speed according to ambient temperature. Here's one example:

They are meant for exhaust fans in computer and stereo cases. I mounted one behind the fridge, and my fans only run when necessary, and at the lowest possible speed. Cost almost nothing and work really well. The fans are virtually silent most of the time.

cruisefx, I know the fan your talking about, from princess auto, its a fairly heavy duty fan, I really liked the computer fans for the reason of very little electrical usage, and the benefit of a very quiet operation,, I tried to do it without removing the fridge, but I just didn't have enough space to get my hands up and in there to install them, the removal of the fridge is a lot easier than it appears, it really only takes about ten minutes, and I was able to do a much better job with the fridge on my work bench, ,if you have any more questions, , please let me know,,, thanks,,,,
