I have replaced 4-5 t/stats over the years on SUBURBAN HEATERS and have yet to see a fuse/fusible link or other device as you claim. May be getting blind, but after replacing the stat, the element came back to life.
perhaps my description was inaccurate when i called it a "fuse" but as you can see in this
picture / link - the thermostat /high limit switch has a wire (fuseable link?) that will melt & create an open circuit which will prevent current from reaching the heating element.
That wire is the physical connection between normal t-stat and high temp t-stat.
The high temp t-stat is 'resettable' when it trips open
Normal t-stat should open at 130*F and high temp t-stat should open at 180*F.
The wire can melt..but that is due to failure off both t-stats not opening OR electric element shorting and high amp low.
The t-stats should not have to be replaced unless something has completely failed.
