Abstract
An automatic ice maker includes an ice-making tray rotatable between an upright ice-making position, and an inverted ice-discharging position. A container disposed beneath the tray receives the discharged ice. A cam wheel rotates with the tray and includes first and second cams that actuate first and second switches, respectively. A controller connected to the switches determines the position of the tray on the basis of the states of the switches. A lever detects whether the container is full of ice. When the container is full, the lever actuates the second switch in order to prevent further ice-making operations, regardless of the orientation of the first and second cams.
