It is over thirty years old.The automatic shut-off thingy
quit working about twenty years ago.

The easiest way to make an auto-shutoff "dryness" control is to stick
a thermostat in the output air stream. As the clothes dry, the air
temperature rises. The higher the temperature, the dryer the clothes.
If this thermostat fails, the dryer will no longer automatically shut off
at the selected dryness.

Adn start a fire? Don't depend on the thermal protector....

The "dryness" thermostat isn't intended to provide overheat protection.
