Whirlpool Electric dryer only has hi heat

My ‘infinite temperature selector’ does not seem to work. I only get high heat no matter what I set the selector on. I have checked the temperature selector with ohm meter and it seems to be working. I have checked the two thermostats(operating and hi-limit) and both have continuity.
Can anyone help?
thank you

How did you check the temperature selector switch?

Did you check the thermostat heater (#16 on the break down diagram)?

dryer works now…replaced the operating thermostat/heater assy.

I’m glad you were able to fix it.
