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 the thermostat fails, the dryer will not longer automatically shut off at
the selected dryness.
