This high temperature control is a safety, manual reset control,
which senses the temperature of the shortening. If the shortening
temperature exceeds 425°F (218°C), this switch opens and shuts
off the heat to the frypot. hen the temperature of the shortening
drops to a safe operation limit, manually reset by pressing the red
reset button. The red reset button is located under the control
panel, in the front of the fryer, to the right of the drain. Once reset,
the frypot starts heating.
