WillisThat website you liked us to is GREAT!:) Thanks
For those that want to know how the actual fridge works, see this page. It is the most complete and simplest version I have found explaining how the absorption fridge actually works. Actually the phrase, "An experiment in gas laws" does come to mind when reading it....
How the Fridge worksAlso doing some more digging, see here on the Dometic site for an animation of one working.

Balvat,
And a big thank you to you too. :) After your lead, I went to the Dometic site and downloaded the new manual for my RM2652. The Cutoff thermostat, called a "Thermofuse" by Dometic, shows in the parts list wiring diagram.
RM2652 Parts list BUT does not show up in the users manual wiring diagram.
RM 2652 user ManualSo all the literature is not up to date yet. And I could not find the "thermofuse" listed as a spare part. But did find reference to the "Thermofuse" as part of the actual cooling unit assembly on some other models. Like on this http://www.dometicusa.com/pdf/3309836.009[1].pdf It shows up on page 12. (I can't get it to hot like with the [1] inside the link from Dometic. Will have to cut and paste.)
This may fit with what TimsRV was saying that it is not available as a spare part as he was told. It's like you only get it when you buy the entire cooling unit...:h I would hope that is not the case as if it is, well the aftermarket trail is where I'm heading.
Again thanks to all for sharing. We keep it up and we may actually understand the real problem. We are in lack of a good picture of the boiler tube area where the crack is located.
