An ice barrier for a selective ice cube and crushed ice dispenser having a crusher section including a crusher arm mounted to a horizontal shaft axially rotatable in either direction, and a stationary crusher arm mounted to one side of the shaft. When the shaft is driven in one direction, ice pieces fed to the crusher section are caught and crushed between the rotating and stationary crusher arms. However, when the shaft is driven in the opposite direction, ice pieces escape down the side of the shaft opposite the stationary crusher arm thereby avoiding being crushed. The ice barrier is frictionally coupled for rotation with the shaft between a first position in the whole ice piece path and a second position out of the path. Accordingly, the ice barrier blocks the whole ice piece path when the crusher is operated in the ice crushing mode.
