Wanted to know on the thermostat mounted on the heater next to the thermo fuse. It has 1.4 k ohms of resistance. That’s with one lead of the terminal so you don’t measure anything else in the circuit. Can you tell me how this part works? Just would like to know for my own knowledge. Some have 4 wires on them? So how do they work?
The thermo fuse was open, A new one put in and it blew that one to. Dryer was clean inside and blower was tight. Good air flow, vent was clear.

The 4 wire thermostat should have 2 outside terminals and 2 inside terminals. The 2 outside terminals should be normally closed and have continuity. The 2 inside terminals should be normally open and should not have continuity,however this cycling thermostat is most likely not your issue. Check the element from each pole to ground as it may be causing element to stay on at all times. I am taking as fact that there is good airflow,so so also be sure that the high limit cutoff on the heater housing is replaced. I have attached a video on the heater replacement.
