Refrigerator Vent Fan

[MikeDavies]

Need to give our Dometic fridge more air flow.
Has anyone tried this type of fan?

I'm trying to get away from having to install a fan in the vent on top of the coach.

Thanks

That's the same as the one I'm using out side I just zip tied it at the out side bottom blowing up.I also have a small one just like it on the inside. Inside refrigerator temp. 34 degrees.

Nice....but, IMO, not as good, (energy wise), as a 12VDC fan, (or fans), when driving and/or boondocking.

I took a piece of shelving unit and made a mount to attach two 30 CFM squirrel cage fans to the outside grill of the refer. This was three years ago. I lowered the numbers on the refer two numbers and has worked well for three years. Only problem I have had was the recall went off coming out of Yuma AZ. Learned that if I hold a strong magnet to the upper right corner of the recall it will reset itself. If it were to keep going off I would have a problem but if it resets you should be good to go.

I've been considering adding fan as well. With the roof vent mounting, how do you find a 12v line to feed it? We have a Norcold and I've been led to believe that there are no 12v leads on the back; nothing I can find in manual or circuit on back of fridge give any indication. Any suggestions are welcome. Thanks!!

Interesting. If you search on the different forums you will find lots of threads about the Norcold. What model is it?

It's on the thermal controller which is located in the middle of the photo below with a red LED on:



BTW, up to 4 fans can be connected to one thermal controller.

Thank you,
I see it in the slide show pics.

I pulled the roof vent off of mine today to measure the opening. The way its designed, I'm surprised any air gets through there. Of course it has to keep water out. I wanted to use 2 computer case blower fans but I'm not sure they will work.

I have 4 computer fans across the opening below the screen. Wires together and controlled by a button thermostat and 2 more in the side opening blowing up from the bottom also on the thermostat. I found button thermostats on E-Bay that activated at 10 degrees lower than the stock one and used one to replace the stock one and the second one for my added fans

We have one of the infamous Norcold 1200 LRIMSS 4 door refer/freezers that had the cooling unit fail. We had a Amish cooling unit installed and the fans are to help it as much as possible. It seems to work well.

Jim does the multiple fans across the top restrict the natural draft when the fans are not turned on (cooler days) of do they pretty much run all the time?

The OP is asking about a fan in back of the fridge....
However, one inside is not a bad idea.
I have one similar to yours and it improves cooling and helps prevent icing of the fins.
