A salamander-type overhead broiler/cooler has a base on a support adapted to hold a foodstuff to be heated, a heating unit vertically displaceable on the support energizable to radiate heat downward at the support, and a horizontal light curtain at a predetermined spacing fixed relative to and below the heating unit so that the light curtain can be broken by a foodstuff on the base when the unit is lowered. A motor is connected between the unit and the support for vertically displacing the unit and the light curtain on the support and a controller connected between the light curtain and the motor means arrests downward displacement of the unit when the light curtain is broken by a foodstuff on the base.
