How freezer ice makers cycle

Transcript

A solenoid valve opens for just enough time to fill the ice mold, while the freezer does the real freezing work and a thermostat watches until the cubes are ready. When freezing is complete, the machine gives the mold a brief warm-up with a heater, or twists the tray in some models, so the ice loosens without a splash. Then ejector blades or a rotating arm sweep the cubes into the bin, and the cycle begins again as the next fill starts. A feeler arm or bin sensor rises when the bin is full, and that shuts the machine off until ice level drops again.
