My old dependable dryer - with a new heating element - and with the vents all checked and cleans does not heat up continuously and is running cooler than usual so I'm pretty sure I need a new thermostat- but which one as I have 2 according to the Whirlpool customer service line- a "thermostat high limit" and a "thermostat operating". which ine to change?

It is likely the operating thermostat that needs to be replaced.

The high limit thermostat is there to cut the heater off if it over heats.

The operating thermostat is for the operating temperature.
