I thought using a generic thermal fuse on that Whirlpool dryer was fine, but the new one blew again after a week.
Turns out the high-limit thermostat was also bad, which I only found after checking the whole circuit with my multimeter, so what's your go-to method for diagnosing a thermal cut-out loop?

Honestly, I've gotten burned by that before. Now I always check for voltage drop across each part while the dryer is actually running and hot. A part can show good continuity cold but fail under load. Found a high-limit that way, it would pass a basic test but showed a two volt drop when the heater was on, which was just enough to keep cooking the fuse.

My buddy Dave in Phoenix had the same thing happen on his Kenmore. He ended up pulling the whole thermal cut-out loop and testing each part on the bench, found a cracked heater coil that was shorting.
