15” Undercounter Ice Maker Ice Production Cycle


  • 15” Undercounter Ice Maker ice production cycle
  • How does ice maker use sprayer to make ice?
  • What causes ice maker to stop making ice?

Steps to Verify Issue:

Depending on ambient conditions and water temperature, one ice production cycle takes approximately 30 minutes.

  1. Water fill cycle. The water inlet valve purges old water from the system.
  2. Refrigeration system start-up. The compressor starts after the water fill cycle and stays on throughout the freeze and harvest cycles. The condenser fan motor starts and runs throughout the freeze cycle.
  3. Freeze cycle. Water is sprayed into the inverted cups. The water freezes layer by layer until an ice cube forms in each cup. The control system adjusts the length of the freeze cycle to conditions.
  4. Harvest cycle. The evaporator warms, allowing the cubes to be released and drop into the storage bin. The control system adjusts the length of the harvest cycle to conditions. At the end of the harvest cycle, another freeze cycle begins.
  5. Automatic shut-off. The level of ice in the storage bin controls the automatic shut-off. When the bin is full, ice will contact the bin thermostat, which cools, signaling ice production to stop. When the ice level drops and ice no longer contacts the bin thermostat, it will warm, signaling ice production to resume.​
