Whirlpool electric dryer, Model LEC6646ANO. On all 3 temperatures (high, medium & low), it gets very hot; as if the heating element won't cut off and on. But when it gets to the ''cool down'' part of the cycle, the heating element does properly cut off. Help please!

You have not provided a model number so I do not know if you have an electric or gas dryer. Your model number may be on a label when you open the door.
1.) Air Flow Problem - Over time lint accumulates in both your hot air distribution manifold as well as you wall air duct. This will shut you down.
2.) Week Ignitor (Gas Dryers) - The ignitor in a gas dryer will glow red. The ignitor can glow red yet not have enough power to open your gas valve.
3.) High Temperature Thermal Switch or Fuse - In both electric and gas dryers you have a high temperature thermal fuse or switch. In either case, when this component is bad and reads any temperature, high or low, it will shut you down.
That is all I can tell you without knowing your dryer model number.
It may be as simple as checking your lint filter.
If you use fabric softeners sheets, they tend to clog the lint filter holes. Washing it with soap and water will restore it back to normal and will allow the circulation that the dryer needs to properly dry your clothes.
The first step of the fix has been done by cleaning the lint filter and the vent system.The next step is replacing the thermal cut-off and the high-limit thermostat both located on the blower housing. It is common that the dryer stops heating when the thermal cut-off blows open due to the failure of the high-limit thermostat to cycle off and regulate the heater temperature. The thermal cut-off cuts power to the heating element should the high-limit thermostat fails and the dryer temperature goes extremely high as a safety feature.

On a low setting the exhaust temperature should average in the 120-125°F range. On medium the temperature should average 130-140°F and on high 140-155°F, depending on the dryers design. Those temperatures should be basically the same with or without clothing.
