A thermostatic bin control sensor uses a thermostatic bulb hanging from the ice maker to determine the ice level in the bin. The bulb contains temperature-sensitive fluid that expands when the temperature drops.
There is some kind of lever (traditional switch ) - a pressure switch under the ice collection area. Once the amount of ice hits a certain weight, the production mechanism is deactivated.
Some refrigerators use an infrared beam to sense the level of ice in the ice bucket. When the ice level reaches the top of the bucket, it interrupts the infrared beam. The control board then shuts off the ice maker. When the ice level drops below the beam, the control board signals the ice maker to make more ice.
When the ice reaches a certain thickness (depending on your ice type), the sensor detects a drop in freezer temperature and signals the ice maker to begin the dump cycle.
Your ice maker has an automatic shutoff. As ice is made, the ice cubes will fill the ice storage bin and the ice cubes will raise the wire shutoff arm to the OFF (arm up) position. NOTE: Do not force the wire shutoff arm up or down.
Most ice makers can be left on all the time in order to ensure that you always have a fresh supply of ice. Like refrigerator ice makers, these appliances are typically designed to run constantly.
A thermostatic bin control sensor uses a thermostatic bulb hanging from the ice maker to determine the ice level in the bin.
To begin the ice-making process, a timer triggers the water valve, which fills the ice mold with water.
In conclusion, the frequency at which a Frigidaire refrigerator's ice maker dumps a tray of ice cubes typically follows a timer-based cycle, with most models doing so every 1 to 2 hours. However, this can vary based on the specific refrigerator model, user settings, temperature, usage patterns, and ice maker design.
The cycle is usually controlled by a simple electrical circuit and a series of switches. In the diagram below, you can see how the icemaker moves through its cycle. At the beginning of the cycle, a timed switch in the circuit briefly sends current to a solenoid water valve.
Clogged water lines
Water lines won't be able to deliver the proper flow of water to your ice machine if the line is too small or plugged by mineral content. The cold temperatures of the winter months can lead to frozen water lines, which is among the most common ice maker problems caused by cold weather.
In ice makers, a timer controls an electromechanical valve called the solenoid valve. The solenoid valve uses a magnetic field to generate and control the amount of water used to make the ice. The timer opens the valve to dispense water into a metal or plastic mold.
There are two methods for this: either an optical sensor or a mechanical arm, which detects when ice has piled high enough. If your ice maker won't stop making ice, it means ice is not piling high enough to reach the sensor or arm, typically because the ice bucket is not in the proper position.
Problem With Water Inlet Valve
If this valve is not shutting off properly, water will continue to flow into the ice maker, causing it to overflow with water and ice. Water inlet valves can also become stuck open, which will cause a steady stream of water to leak from your ice maker.

Once the ice maker has been connected to a power and water source (aka the plumbing line connected to the back of your refrigerator), the ice maker cycle should begin automatically. At the beginning of the cycle, an electrical signal is sent to a water valve to fill the ice mold with water.
If you're wondering if you can leave a portable ice maker on, the easy answer is that yes, you can. But keep in mind that the insulation and freezing process on a portable ice maker is not the same as that of a freezer.
If the refrigerator or ice maker was recently installed, you should allow 24 hours for the refrigerator to cool enough to begin making ice. Once the refrigerator is completely cooled, the ice maker should produce a batch of cubes about every three hours, and it may take up to three days to fill the ice bin.
If you work with really pure water and cool it slowly to produce supercooled water as a liquid, there's different outcome. When an impurity (e.g. an ice crystal) is added to this supercooled pure water, it speeds up the crystallization process even more. The water instantly freezes solid with no slush in it anywhere.
Under those proper conditions, most ice maker cycles will produce about 8-10 full cubes (depending on the size of your tray) at a time. This cycle will repeat every 90 – 180 minutes until the ice tray is full, which can typically hold 4-11 lbs of ice.
Lower the Freezer Temperature: the water in the ice tray freezes quicker, triggering the tray thermostat to warm and release the ice, which starts the process all over again. The circle of life in the ice maker machine! To make your ice maker work faster, simply lower the freezer temperature by 3-5 degrees.
If the sensor malfunctions or is damaged, it can cause the ice maker to display "ice full." Temperature sensor malfunction: Another reason for the ice maker displaying "ice full" and not making ice could be a temperature sensor malfunction.
Sadly, with every piece of equipment comes a lifespan. With proper cleaning, a quality ice machine will last around 4 to 5 years on average, sometimes even longer. So how do you know when it's time to replace your ice machine? The first thing you need to do is locate the problem.
The ice level sensor is located on the right side wall of the ice storage bin and monitors the ice levels. If the sensor is blocked or dirty, the ice maker could stop ice production.
