That would definately be an improvement.

*******If you own a 2007 or 2008 or newer Norcold or a Dometic RM7400 series refrigerator, please read this: Apparently Norcold has changed their light/switch assembly beginning in 2007 models. As yet, we have not been able to find a constant 12v source in the light assembly. We have had customers tell us how they're installing it. Send us a message asking for alternate installation instructions. Be sure to include your regular e-mail address. We can send you simple instructions WITH PICTURES to guide you through the alternate installations.

If anyone has the above quoted model and installs this, please post as to how it went, with your Fridge model number.

Thanks.

when I purchased the fan they told me that if the light doesn't have 12v constant use the drain tube or sneak by it a grab 12v in the rear of the fridge
This is what he sent.



I have many customers with the newer Norcold and Dometic units using the drain tube as a route for the hot wire. Here is the information:

Going through the drain tube......

You do NOT need to cut or splice any wires.

I was able to duplicate this set up on my own refrigerator to verify the fan would run. I have not been able to actually USE the fan set up this way to see how the refrigerator does. My concern is that the wire could possibly block the drain tube resulting in overflow in the refrigerator. The customer who sent me these pictures of his install has been using his this way since early Sept. '09. He said he would let me know if anything came up, but on 9/17/09 he emailed me everything was fine. I haven't heard from him since so apparently nothing unusual has come up.

Here's what he wrote...."I used a fused (.5A) wire and snaked it from the outside up into the fridge compartment. I would say if you where going from the inside fins it would take maybe 3 feet to safely get over to the 12 volt supply. My water tray inside the fridge pulls out and disconnects from the drain tube, this would make it easier to feed wire from inside." He also stated, "took less then 5 minutes installation time".

I can't vouch for the 5 minute part. It took me 18 minutes and 3 attempts to get the wire down the tube. The easiest way for me was to go from interior to exterior. I used an 18 gauge wire I purchased at an auto parts store. I think the 18 ga was a little too much. You could probably use a 20 ga and be better off.

I already have a cooling fan on the condensing coil of my fridge, I thought they were now fitted as standard, to assist cooling in hot weather mine never runs, never seem to get hot weather.

I did this mod a few years ago from an old computer fan I had laying around. It sure makes a difference I can attest.

I installed that fan also. It did not lower the temperature of our fridge. It did keep the frost off of the fins though.

I installed it too and thankfully, constant dc was available at the light of my standard-issue dometic 7.5 cu ft fridge. The directions say to remove the fan while dring down the road but mine has stayed put just fine and my fridge is in the rear most corner of the TT.

We just use the little blue cube. It does fine.

We put a dual fan in our fridge a couple of summers back exactly like the one brokeinct showed and it has worked well being wired into the fridge light. However, one of the fans recently quit working and the other is starting to hum, so it may be time to replace. I've wondered if the cold and moisture had any effect on their performance long-term.
