Jim or anyone else, do you know what the electrical draw is on this unit?

Jim...If your keeping track, add my name to the special product edition. I am hoping to cut the weight of ice and my performance cooler from my short trips.

Got it and I'll ask about the draw in my email Sunday night. It can not be too high as the wires to the light switch where the power is are not that big.

From the Fridge Fan website:

How much power does the Fridge-Fix use?We designed the fridge fix for those who use their RV fulltime. If you dry camp, and have no access to electricity, you should only turn the fan on when you need it. It is impossible to comment on how fast it will draw your batteries down, due to all the different RV's on the market. We do know that the Fridge-Fix draws .5 amps (1/2 of an amp...).

I'll take pics when done and report on how it went.
Well, to save some money and also address the opportunity to move air across the cooling fins in the refrigerator and improve overall cooling performance I came up with a solution and it is now operational.

1. Installed two 1/4 zinc plated steel cross bars in front of the cooling fins
2. Removed the door light assembly and tapped into the 12vdc supply and added a small microswitch and a single supply line for the fans.
3. Installed the fans at a slight angle blowing directly into the cooling fins. They are now attached with rubber bands but will eventually be permanently mounted in place.
4. I ordered grill covers for the fans so I won't complete the installation until they are received next week.

I am very pleased with how this system turned out:
-120mm fans are large and blow air across all of the cooling fins
-Very high quality fans with hydraulic, sealed bearings for long life
-Very low current draw; .1 amps total (measured; both fans running)
-Very quiet...I can barely hear the fans running with the refrigerator open
-Fans moved a very large volume of air; 38cfm each, 76cfm total
-The system is mounted vertically in the back of the refrigerator in front of the cooling fins so that no food storage space is used by the system

This is where I tapped into the 12vdc supply and installed a microswitch to turn the fans on or off. Notice the access hole I added to activate the switch.



Here you can see the support rods for the fans. The fans will eventually be attached to the rods with heavy tie wraps.



This shows the layout of the two fans. They are about 3/4" away from the cooling fins.



When I receive the fan grills late next week I will finish the installation. When done I will cool the refrigerator down with and without the fans running. It will be interesting to see the results which I will share including finished installation pics.

...my total installed cost: Less than $10.00.

You have the 6.7 in your 19? correct? which wire in the light switch did you tap into? the Brown wire? we will need to do the same. I like your fans….

Jim, mine is a model RM8551 and is 4.3cuft. However, I'll bet the light assemblies are the same. The wiring on mine on the connector from top to bottom is purple, red, black, white. I tied into the white lead circuit inside the housing and soldered to the bottom of the circuit board on the appropriate power transistor terminal lead. This seemed like the easiest connection point to solder to...then ran through the microswitch and out the red lead to the back. Your unit has an on/off switch so you can just solder in a lead wire.

Very nice work!
I really like the use of the stock moulded shelf mounting points for both the support bars and the wire routing - clever.
