Abstract
An apparatus and a method controls a heating device in a laundry ironer. The apparatus includes a frame and an ironer cylinder. The ironer cylinder rotatably connects to the frame and has an interior surface and an exterior surface. The interior and exterior surfaces extend substantially from a first end to a second end of the ironer cylinder. A line of sight temperature sensor connects to the frame near the first end wherein a line of sight of the sensor is directed at a portion of the interior surface of the cylinder. As the ironer cylinder rotates and is heated by a heating element, the temperature of a portion of the interior surface is sensed. Based on the temperature and a threshold, the state of the heating element is changed.
