    Electrical advice refrigerator fan mod

    Okay all I have one fan out on refrigerator and donít want to pull frig to replace. Iím thinking of going with two aero fans on top vent and maybe one down low to blow up. I would like these to be thermostat controlled so they only run when needed. Anyone have advice on thermostat and or lower fan as well as any install advice? Fans look fairly straight forward.

    Thanks in advance!,

    What is the frig model?
    I put 2, 6 inch computer fans in at my top vent.
    They are facing out. The Norcold 1210 factory fans are on a thermostat.
    I disconnected dc /ac power.
    Spliced the new fans into the factory fans. The factory fans are controlled by the thermostat at the top of the fridge. So now two fans blowing up and two blowing out. All four fans cycle on and off via the factory thermostat.

    I have the 1210 as well@-almost looks like I can get to stock fan but figure this mod may be better-Debating about inside fan on fins as well.

    While we have a residential refrigerator and this isn't an issue for us, I did stumble across a FaceBook posting for these frigs that is simple and is claimed to help chill the refer.

    If it can help any members here, then great! Hope it's OK to post this FB link....

    Re: Electrical advice refrigerator fan mod

    You're going down the same road I did. I bought 5 12dc muffin fans and installed three at top vent and two at the bottom vent. I left them running all of the time and they were very quiet from the inside of the rig. It helped a little, but if your fridge is in a slide then, unfortunately, the whole thing is set up for a failure. I can remember some of my older rigs whereby the fridge vented straight out the top, and these worked pretty well. The problem is that when installed in a slide the manufacturers recommended installation is extremely hard to accomplish, particularly on an assembly line. Look around and you can find the installation requirements for your fridge, then look at the installation by the manufacturer and see how closely they followed the instructions. I eventually ended up replacing the LP fridge with a residential and I'm very happy...

    If your 1210 is in the slide
    Remove the aluminum baffle, cut two screws left and right from outside. Mount 2, 6 x 6 dc computer fans blowing out. Tie them into the Norcold fan wiring.
    Also make sure you have a vent cap on the exhaust stack. It allows the heating process to do it's magic to the absorption ammonia.
    Last year I left the fridge on 3and 4 ice cold beer.

    I did exactly that. Two Aero fans on top and one on the bottom. I attached the thermostat to the fins at the top. You can get the thermostat from several places even Amazon ( google RV fan thermostat ). Just zip tie the fans to the vents. Keep the existing metal baffle in place. This directs air to flow over the top fins. I used metal HVAC tape to cover any areas around the top of the fridge to prevent air from being trapped there. This all improved things a lot.

    You might be able to use the existing thermostat. Try that. There is an existing 12v source in the back of the fridge is you do not use the existing thermostat. I added a 2 amp fuse to the system.

    I have a DC only refer so no real heat to scrub off the back of the unit. But I needed more circulation inside so I added a USB powered fan.

    That's interesting about the vent. I noticed that the vent for the burner vented straight up into the area above the fridge. This seems counter to common sense because I was trying to get the heat out of that area with fans. I thought about putting some kind of 90 degree piece on it and running it out the top side vent but finally just bit the bullet and pulled it.
