It is imperative that the cooling units on the Norcold 1200LRIM get proper ventilation. These units are shipped with two muffin fans mounted on top of the coils. Drawing air upward over the coils is m...

Hi Dennis,
Nice work & nice pictures. I've been toying with doing something similar "one of these days". A few years back, our refrigerator seemed to be struggling to keep things cold, so I rigged up a muffin fan on the bottom blowing upward. That seemed to help. It ran all summer, then I disconnected it in the Fall. The next year (and ever since) the refer seems to work fine without it, so I have not really thought much about making a permanent solution. But most of our camping is done here in the Northeast part of the country, so the temps are a bit more moderate than folks experience down south. :)
I do have one concern with your design, but might not be a big deal. I was wondering how those fans effect the cooling operation of the refer if they aren't running. For instance, suppose there is a failure somewhere and the fans aren't drawing air up the coils. I'm just wondering if the stationary fan blades would impede the normal passive air flow and cause other problems with the cooling unit. If that's the case, then maybe using just 2 fans might be better as there would be better airflow if the fans weren't running?
Probably a non-issue, I guess it's just my suspicious nature of relying too heavily on $16.00 worth of Chinese made fans! LOL
Thanks for the post.
