A method for displaying preheat or oven thermal conditioning times in a countdown timer for both thermal and thermal convection ovens is provided. The method has the steps of providing an oven having an oven cavity, a heating element, a control panel for inputting cooking parameters, and controls connected to the heating element for operating the oven; selecting a preheat temperature using the input control panel, providing a preheat time by using the control system; determining if the oven cavity is pre-conditioned; executing a preheat cycle when the oven is not pre- conditioned; displaying the preheat time in a decrementing manner using the display; and ending the preheat cycle when the decrementing preheat time equals zero. An oven having an improved preheat system is also provided.
