Your ice maker isn’t just freezing water—it’s a tiny, automated factory running on a perfect little cycle. Think of it like a relay race: first, water has to show up, then it gets super cold, then it gets kicked out. But the real hero? It’s a part called the thermostat or temperature sensor.
When you push that little arm on the ice bin down (or when the bin gets empty), you’re basically ringing a dinner bell. The ice maker says, “Okay, time to make cubes.” A valve opens, and a measured amount of water floods into a metal or plastic mold. Not too much, not too little—just enough to make perfect little squares.
And here’s where it gets clever: the mold sits right next to the freezer’s evaporator coils (the super-cold pipes that keep everything frozen). The water touches the cold metal, and within minutes, it starts to freeze from the bottom up. Why from the bottom? Because cold sinks, and so does freezing—like ice forming on a pond in winter.
