I reached out to the designer/builder of the ARP Frig Defend.
Here is his reply:
Thanks for the feedback, and letting us know that you have an Amish cooling unit.
First and foremost, IR temperature readings are challenging to get an accurate reading.
Next, 329F = 165C, this is actually a low boiler temperature, but the boiler could be warming up or cooling down?
The normal range for a Norcold 1200 is 185 to 195C (365 - 383F).
Please note that the "normal" temperature for any cooling unit is dependent upon the pressure that the cooling unit was charged with. Also note, 482F (250C) is not the point at which the ARP shuts off at. Also, please see letter from Norcold to ARP at this link:
https://www.arprv.com/arp-versus-norcold-recall.php which states that the recall will only respond after 800F (427C), which is also the yield point of the cooling unit tubing with the normal charge pressure.
Thanks for getting this information from Paul. His reply to me was:
"329 degrees is less than 482 degrees, thus the sensor is not mounted too close to the heaters."
So he gave you more information than he was willing to give me (the customer!).
most of the time his response is to read all of his many many pages and webpages and links of documentation.
Thanks again for the information, it was helpful.
