The present invention relates to a temperature compensated timer for a heating appliance that heats a food item during a heating cycle. The timer includes a coil (312) having first and second terminals and presenting a resistance between the terminals that is a function of temperature changes of the coil. A timing circuit is coupled to the first and second terminals of the coil. The timing circuit operates to drive a current through the coil to maintain a heating cycle and to generate a delay signal a delay time after the heating cycle is initiated. The delay time has a value that is a function of the resistance of the coil. The delay signal is operable to remove the current from the coil to terminate the heating cycle. <IMAGE> |
