Adding cooling fan to refrigerator?

Can you tell me where you bought the thermostacically controlled switch from?

This is what I added to the fridge compartment on my Torque. Made a heck of a difference. Just set it in there pointing up plugged into the the existing 110v plug in with a 3 way.

Added one in the Storage compartment for the 110v fridge I have in there too.


Hope that helps

My refrig. tended in the mid-40's. A little scary. I got an inside portable refrig. fan from Tweety's that runs on two 'D' size batteries. Instructions said it would run for a month on the batteries. I doubted it, but in fact, it does.

Anyway, back to the topic: it reduced the temperature about 10 or more degrees, despite backing off one position on the temp. switch on the front of the refrigerator. And the temps are much more consistent, so no freezing things at the back while things in the door pockets are too warm. Like milk.

This might fix your problem, and for just under $20, you aren't risking much. Camping World has them, too, 'on sale' for about $16. Called a Frig Airator or some such.

I seen one of those while I was at MB a couple weeks ago and I almost bought it. My fridge stays cold enough but it is on the coldest setting. I am going to give them a second look. Thanks, Will

That is a great looking job. Where did you get the adjustable thermal snap switch from?

Also that last picture of yours, is that taken from on top of the rv looking down the fridge vent?

That looks great. Similar to what came with mine from the factory only mine had two fans.

I sealed the air gaps around the fans with insulation and it helped with air cavitation.

Here is the mod that I did. I give credit to sc3283.

It really makes a difference. Ther refrigerator now gets down to 37-38 degrees. Seems to recover faster.

Fan was $15 from www.allelectronics.com/make-a-store/item/CF-400/12VDC-FOUR-FAN-ASSEMBLY/1.html

Attached to the fan frame is a adjustable thermal snap switch which is set to turn on at 100 degrees.

Used some aluminum bars and rubber feet I picked up a Home Depot.

Total cost around $40

Across the top of the refer, it appears to have horizontal piece of wood. There is a straight tube there on the cooling unit.
Attach a curved paice of metal to the wood and roll it around to attach just above the vent access. There should be some type of support member there.
Check your PMs!

I would leave the space between fans open. I doubt whether closing that up will help and it may even be detrimental.
In the first photo, I would get some metal and install curved piece between the wood member and the top of the opening. Make sure the metal goes between tubes and the cooling unit tubes. The squared off may slow the air down.
Looks good!

Thanks,

Not sure what you are talking about with the curved metal and wood comment?????

Posted for Cummins12V98,

Thank you Barney for posting these pics!

I noticed when I looked at the pics I needed to add insulation between the fans. Those two fans are what came on the rv. I installed the single one with a switch in the lower compartment. I aligned the single fan behind the upper vent slot in the access door and as close to it as possible.

For now I am running the single fan all the time and have the double fans still tied into the controll board. The daytime temps have been in the low 70's and the frig has been steady at 40 degrees on #3 but the freezer is colder than before with the ice getting very hard. So just the one fan pulling air thru the back side of the frig really makes the frig work better.

I have a constant hot wire and inline fuse that I can use for the two fans when it gets really hot to plug the two fans into if the computer does not keep them running all the time.

I will report back when we get to SoCal this fall how it works with all three fans running with the temps 90-100 degrees.

It really helps to seal off the holes around the fans. The two fan pic is looking down from the top access/vent door. They are mounted mid way between the two access doors.

Thanks again Barney
