Claim 7:
8. A countertop appliance having improved cooking surface temperature control, the countertop appliance comprising:
a cooking surface;
a resistive heating element configured to heat the cooking surface; and
a temperature controller comprising:
at least two electrical output contacts selectively coupleable to the resistive heating element;
a user input configured to receive a desired temperature setpoint for the resistive heating element;
a temperature sensor in heat conductive communication with at least one of the electrical output contacts, so as to receive temperature information from the resistive heating element, wherein the temperature sensor is in direct thermal contact with at least one of the electrical output contacts; and
a thermostat configured to adjust an electrical output of at least two of the electrical output contacts to minimize a difference between the desired temperature set point and a measured temperature of the resistive heating element based on the received temperature information.
