Summer is closer to us. So hot days, you need an ice maker dispenser inside your refrigerator. What’s more, The microswitch inside Icemaker has a vital role in the ice maker! The micro switch mainly controls the ice making. 

The ice maker will open the start circuit with a Unionwell micro switch inside when the refrigerator’s internal temperature is under zero. Then icemakers begin to make ice.


Icemaker in refrigerator working principles


Though the ice maker can vary from model to model, they operate on similar principles. So it’s necessary to learn how the refrigerator ice maker typically works! Now let’s begin!


First, open the water pump switch. The pump sends water to a collection sump and pours it over the chilled ice tray. As the water flows over the tray, the water gradually freezes, building up ice cubes in the well of the tray. When you freeze water layer by layer, it forms clear ice.

When the ice cubes fill the bin, the highest ice cubes will block the beam, and then this action will then send a signal that stops ice making; we have made enough ice cubes.

To archive the perfect ice making, the temperature in the refrigerator should be zero degrees Fahrenheit or lower. The Icemaker, the refrigerator parts only begins to work at zero degrees Fahrenheit or lower. The Icemaker runs the gear motor to turn a rake or twist the tray to eject any frozen cubes into a storage bin. At the end of this cycle, the ice maker will run the water pump and send water through a hose and fill tube to refill the ice maker tray. Usually, the home’s water pressure is between 20 and 120 pounds per square inch for the value to work correctly. The little ice will be dispensed through the chute when the ice dispenser lever is depressed.

At least, the cycle continues until the ice tubes fill all bins to block a beam in the ice maker, which will automatically turn switches off the Icemaker.
