Your comment really interests me. I was a Certified Master Tech factory trained by Dometic for 20 years and have never run into a single instance like the one you describe, although I worked on hundreds of Dometic refrigerators.
The fusible link and thermal switches on and near the stack came about with the refrigerator fires, lawsuits, and thousands of recalls.
I don’t doubt for a minute the details of your report, but never thought to carry fusible links as I never had to replace one. If this is as much an anomaly as my own experience would suggest, I am scratching my head trying to figure out what is different here. I am also wondering if anyone else here has had the same experience.
