Changing Refrigerator to 12V DC
My bus came equipped with a large Norcold 1200 double door refrigerator/freezer. It worked on electricity but not on propane, which I recently discovered was that the ignitor coil had cold solder joints and had disconnected from the controller board.

I made the decision that my bus would be propane free, (opps now thinking of it for engine HP boost LOL!)..
But anyway this latest project that went very smoothly; was upgrading the refrigerator from the typical RV propane/electric cooling to a 12 DC compressor to be more power efficient inline with my solar power goals.
I purchased my conversion kit from:

They have videos of how do the replacement/conversion of the cooling portion of your refrigerator/freezer. They offer replacements for most RV type of your refrigerator/freezer.
Here's the video of the basic procedure that I performed to upgrade my refrigerator/freezer.

I first heard about this conversion from the youTube channel "Morton's on the Move". https://www.youtube.com/channel/UCir...xZZApeIe0a5-6Q
The videos covering their conversion is:

And since the proof is always in the numbers, here's a history chart from my first run:

I was able to install my automation temperature sensors by running them in through the holes for the drip pan drain and the ICE maker.
I realized on my way home after powering it up for it's first time that I forgot to clip the refrigerator temperature sensor to the appropriate cooling fin, just left it hanging. So as you can see from the graph's it over cooled the interior, but hey it works!!!
Still tucking it away and I will document another modification that I made in a future post.
