Abstract
A cooking appliance includes an oven cavity, an electric heating element, a control element for selecting an oven cavity temperature, a timer and a calibration system for regulating operational parameters of the cooking appliance. The calibration system adjusts operational parameters of the cooking appliance based upon an amount of time required to achieve the selected oven cavity temperature. Preferably, the timer measures the amount of time needed to achieve the oven cavity temperature during a no load condition in order to set a baseline. Once the time is determined, the calibration system adjusts offset temperatures, hysterisis temperatures and/or cooking times to account for variations in power delivered to the oven cavity.
