GE spacemaker electric dryer model WSM2400L

When dryer is turned on, coil heats up and turns red; high heat flows thru the drum and exits the vent. After a few minutes the heat stops and does not turn on thru the rest of the cycle. I checked the coils. None are burned or shorted. There is no lint buildup in machine. Exhaust vent is clean. Pleaty of air flow to outside.

I assume it is either the T'stat safe; Thermostat safety; Thermostat heater or Control thermostat. I have not checked them for continuity yet. I was hoping, based on the info above, someone might know which one is causing the problem.

Any suggestions would be greatly appreciated. Thank you in advance.
