We’ve got a domestic three way fridge and want to connect a fridge fan. What is the best place to make the electrical connections to?
 
Sounds interesting why are people fitting Them?

Can someone put a link up for the fan kit, anymore info would be good.
Thanks

Ian, I fitted two 'silent' computer fans Gelid Solutions Silent 6CM 60mm Fan Cooler Case PC Computer Cooling 3 Pin Quiet | eBay

Seperate on/off switch to turn fans on 5 x 12V ON/OFF Switch Car Smart Switch Round Rocker Van/Dash/Boat LED/Light BLUE | eBay

One of these: 3in1 Digital LED Display Temperature Thermostat Refrigeration Heating Controller | eBay

I found it a bit fiddly to do but a numpty like me did it and it worked a treat. It certainly made a difference, one hot day it dropped the temperature 5 degrees.

If I can find the pics I will post them.

Some fridges struggle to keep the temperature down in hot weather, by fitting fans into the upper vent, it sucks the hot air that builds up behind the fridge and blows it outside.

I fitted two fans side by side in a frame made from pvc trunking, very light and easy to glue to the inside of the vent.

My fridge seems to be ok what ever the weather, would fitting one tho improve efficiency?
I’m always up for tinkering about with the van :)

In the most basic of explanations refrigeration is shifting heat from one place to another, By fitting fans you are increasing airflow and allowing a better disappation of heat. In practical terms the fridge should be more efficient

The other type of fridge fan

The other type of fridge fan is fixed inside the fridge compartment, up against the cooling fins, ensures air is gently circulated,

I'm looking for one of these as my fridge keeps going into random defrost every 10 days or so.

i reckon the best place is on the inside of the top vent , blowing out .

On our last van the fridge was next to the settee with leisure batteries beneath and I found it quite easy to wire up.

I have three behind the top vent so extracting the air from behind the fridge. Some of the fans can be a bit noisy when run on 12v so I have the option to switch in a resistor to reduce the voltage which makes them much quieter.
 
DSC_0466.jpgDSC_0470.jpgDSC_0465.jpg these three pictures show the top of my Dometic fridge with the internal fridge wiring, I tapped into the 12 volt as marked. My temperature control I mounted on the front fascia on the left and a rocket switch on the right to isolate the fans. I clipped temperature probe to the radiator fins at the rear of the fridge.

I got my fans from old PC towers, most are thrown away these days, speak to your local computer repair shop, just make sure they are 12 volt. Cost was zero for me.
