Refrigerator Ice Dispenser Components: Functions and Operational Principles

To prevent frost buildup in your refrigerator, the ice dispenser system is an essential component. Do you fully comprehend how this part operates? Let's delve into the details of the roles, structure, and operational principles of the refrigerator ice dispenser with Supermarket Mytour!

What does the refrigerator ice dispenser comprise?

The Crucial Role of the Refrigerator Ice Dispenser

- Eliminating Frost Formation and Adhesion on the Evaporator Coil: This is one of the most crucial roles of the refrigerator ice dispenser. During usage, frost easily forms due to water vapor condensation in the refrigerator. Without the ice dispenser, frost would accumulate, reducing storage space and hindering the refrigeration process.

- Energy Conservation: By removing frost buildup and maintaining the system's functionality, the refrigerator ice dispenser significantly contributes to considerable energy savings. When the system is not clogged, the refrigerator operates more efficiently, consuming less energy.

- Enhancing Appliance Longevity: The ice dispenser plays a vital role in safeguarding and extending the lifespan of the refrigerator. By eliminating frost formation and maintaining cleanliness inside, it helps reduce the risk of malfunctions and ensures the refrigerator operates efficiently in the long run.

Depending on the machine model and refrigerator brand, the ice dispenser may have some variations. However, the refrigerator ice dispenser generally includes some key components as follows:

The defrost resistor is a crucial component responsible for initiating frost melting within the refrigerator by generating heat. Specifically, when activated, the resistor produces heat to melt the frost on the evaporator coil. The melted water follows a designated path and drains out. Typically, the heating element is constructed with toughened glass, featuring a sturdy outer layer and a mica ribbon inside to generate heat.

This component controls the operation of the refrigerator ice dispenser. The ice dispenser timer is connected to a motor and operates a separate switch. It is considered a crucial component of the refrigerator ice dispenser.

This component functions to open/close the electrical circuit based on the pre-set temperature. Specifically, when the defrost temperature on the evaporator coil reaches the specified limit, the thermal relay interrupts the electrical circuit to halt the defrosting process.

When electric current is supplied to the refrigerator ice dispenser, this is also the moment the timer begins its activation. Subsequently, this component provides power for the refrigerator compressor to start functioning.

After the refrigerator operates for approximately 8 - 12 hours, the timer switches to the defrosting phase, which includes ice and frost removal. At this point, both the compressor and the fan are temporarily turned off.

Next, the refrigerator's defrost resistor heats up, causing the frost layer on the evaporator coil to melt. Once the frost completely melts, the refrigerator's temperature increases to a predetermined limit, triggering the thermal relay to initiate the cooling cycle.

When the refrigerator dispenses ice for about 20 minutes, a new refrigeration cycle will commence. The duration of the refrigerator ice dispensing phase depends on the sensor. Typically, this period extends from 20 to 30 minutes.
