Abstract

A countertop appliance temperature controller configured to provide improved temperature control of a resistive heating element heated cooking surface of a countertop appliance through the use of a noncontact thermal sensor. The temperature controller including a pair of electrical output contacts selectively coupleable to the resistive heating element of the countertop appliance, a user input configured to receive a desired temperature setpoint for the cooking surface of the countertop appliance, a noncontact temperature sensor configured to receive temperature information directly from the cooking surface of the countertop appliance, and a thermostat configured to adjust an electrical output of the pair of electrical output contacts to minimize a difference between the desired temperature setpoint and a perceived actual temperature of the cooking surface based on the received temperature information.
