'Lo All,

>A thermostat to control the muffin fan.

I used the air conditioning side of two old household-type 
thermostats to control muffin fans to exhaust hot air from behind my 
Norcold and to exhaust hot air from around the inverter. I set the 
thermostat to 90 degrees or so.

>To the listee who wanted to know where to get "muffin" fans. They are used
>in PC desktop power supplies - that's where I got mine.

I would highly recommend a ball-bearing type fan, as a sleeve bearing 
will wear out fairly quickly. I found the ones I used online, at a 
computer house. Get the larger ones as they should move the most air. 
I think the ones I got are 4" x 4". I have some smaller ones I took 
out of computers, but they do not seem to move as much/enough air.

The first fan I used behind the Norcold died after only a few months. 
It had sleeve bearings. The new fans and thermostat setup have lasted 
at least 3 years now. I installed two fans behind the Norcold when I 
replaced the failed one. Now, even on the hottest day, the Norcold 
keeps ice and cycles on and off. Before, it ran continuously on a hot 
day and barely kept the refrigerator cool (not cold).


Take care and be safe.
