Abstract
A multiprobe diagnostic system for a cooking appliance using one or more heating elements, one or more error-detecting temperature sensors located near the heating element(s), one or more control temperature sensors spaced away from the error-detecting temperature sensors, and a microcomputer program for identifying and setting error conditions in the appliance based on comparisons in temperature and temperature differentials in the appliance with minimum and maximum predetermined or learned values. Other devices, such as current sensors, are used in conjunction with temperature sensors to augment the diagnostic information obtained from the temperature sensors.
