The best solution to this problem- something the OEM's *should* put in, IMHO, is the ARP refrigerator control, which monitors boiler temperature and reacts quickly to prevent overheating. You will find a bunch of data on that site about the issue.
There are 2 other issues internal to a cooling unit- the Hydrogen can leak out over time (a long time though), due to slightly porous welds (and Hydrogen is a small molecule), and when the sodium chromate overheats, it releases nitrogen. The nitrogen will fill up the lower part of the unit, and is often the cause of cold freezer/warm refrigerator, as the nitrogen displaces the hydrogen in the fresh food compartment.
I looked at the ARP web site. This would seem to answer the second question I had if I understand it correctly. What I was trying to figure out is with a simple HF IR gun which many on here have could we shoot the same spot on the flue where it looks like the ARP temp sensor is installed and develop a tolerance for of level? Sort of a manual ARP system? I think the answer is yes. Although the ARP not only records the temps but shuts it down when it gets too hot.
