ABSTRACT:
A control system for an ice dispenser maintains an icemaker thereof continuously operative whenever an ice storage hopper is less than completely full. This is accomplished by continuing to operate the icemaker while momentarily agitating and leveling the mass of ice in the hopper whenever ice builds up around a thermostat therein, and thereafter sensing whether the ice has dropped away from the thermostat. If it has, the icemaker is maintained in operation and the cycle is repeated. If, however, it has not, then the icemaker is turned off until sufficient ice is dispensed from the hopper to again drop the ice level to below the thermostat. In this manner, the number of on-off cycles of the compressor and other components of the icemaker are minimized in maintaining the hopper completely full, which greatly increases their operating life and reliability.
