Non-Frost Refrigerator wiring:

This circuit shows how to make Non-Frost Refrigerator wiring. In this circuit, we use a door switch, a thermostat, a timer, a fan motor, an overload, a capacitor, a defrost heater, a thermal fuse, and a biometer. This circuit is very easy to make connections. If you want to know more about this circuit please check our youtube video at the below post.

Components used to make the Non-Frost Refrigerator wiring:

01. Door Switch:

Its full name is Double pole single throw. A switch is designed to connect two wires in a line. Such switches have two poles. Both poles are used to open and close the circuit simultaneously. The two poles are connected by a non-conductive material, which has a handle. By turning this handle, two circuits are controlled, one circuit is disconnected and the other circuit is connected. Each Input Terminal connects with 2 output Terminals, and all 4 output Terminals are separate.

02. Thermostat:

Meaning of Thermostat The word thermo means heat and with the help of heat the electrical circuit is switched on and off is called a thermostat. The thermostat switch is the control device of the fridge/refrigerator. which directly or indirectly controls one or more heat sources and cooling systems to maintain the refrigerator’s required temperature. The role of the thermostat is important to automate the cooling system of the fridge/refrigerator. A thermostat switch is a sensitive device that automatically converts the temperature of the refrigerator.

03. Timer:

A timer is a type of time switching device that controls and controls electrical circuits and electrical and electronics devices through time setting (on/off). Timer is basically 8 pin. Like other controlling devices the timer has a coil and when this coil is magnetized, the timer works on/off. The timer has two common ends and each common end has normally close and normally open options. When the timer is set by time, the timer trips at the end of that time and turns the common’s normally closed (on) to open (off) and normally open (off) to close (on). This is how the timer works.

04. Fan Motor:

12V DC Cooling Fan 2 inch 50mm, The Direct Current Fans, or DC Fans, Are Powered With a Potential of Fixed Value Such as the Voltage Of a Battery. It Features Maintenance-Free Double Ball Long Service Life, Bearings, Sufficient Heat Dissipation air Volume, And Air Pressure. A Cooling Fan is any Fan Inside, or Attached to, a machine Case Used for Active Cooling. Fans Are Used to draw Cooler Air Into The Case From The Outside, Expel Warm air From The Inside, And Move Air Across a Heat Sink To Cool a Particular Component.

05. Overload:

Overload Protection is Protection Against a Running Overcurrent That Would Cause Overheating of The Protected Equipment. Hence, An Overload is Also a Type of Overcurrent. Overload Protection Typically Operates on an Inverse Time Curve where the Tripping Time Becomes Less as the Current Increases. This Overload Protector is an Essential Component for Many Sockets. The Top-Quality Overload Protector can Effectively Protect Electrical Products from Power Surges.

06. Capacitor:

This 50 MFD Capacitor Electric motor Capacitor article Series Explains the Selection, Testing, installation, & use of Electric motor Starter Start and run Capacitors used on Various Electric Motors Found in or at Buildings such as air Conditioner Compressors, fan Motors, and some Good Pumps. An Electric motor’s run Capacitor (50 MFD Capacitor) Remains active after the Starting cap has Dropped from the circuit (as the motor has its proper speed), and 50 MFD Capacitor indeed the value of the run Capacitor can affect Motor Speed.

০7. Defrost Heater:

Defrost heaters are used to melt ice formations in refrigeration equipment. They are caused by defrosting water, which freezes inside the lower freezing cold room, collecting in trays or defrost lines. For trays, tubular heaters of various designs are installed. To defrost pipes, wire heaters are wrapped around the pipe. Defrost cable heaters are made in two models, with or without self-regulating elements. Defrost heater is used to help icing conformation in the Refrigerator and is controlled by a Thermostat.

08. Thermal Fuse:

A thermal Fuse or Thermal Cutoff is a Safety Device That Open Circuits Against overheating. It Detects the Heat Caused by the Over-Current Due to Short Circuits or Component Breakdown. Thermal Fuses do not Reset Themselves when the Temperature drops as a circuit breaker would. A Thermal fuse must be replaced when it fails or is Triggered. Thermal fuses only react to excessive temperature, Unlike electrical fuses or circuit breakers, not excessive Current, unless the excessive current is sufficient to cause the Thermal fuse Itself to heat up to the Trigger Temperature.

09. Biometer:

Biometrics is a scientific and technological authentication method based on biology and is used in data assurance. Biometrics refers to statistics about humans. Biometrics identification is a widely used identification method in computer science. It is used to monitor an individual. Biometric identifiers identify a person by looking at certain physical characteristics. Biometric devices convert a person’s personal characteristics into digital codes.

10. Relay:

Voltage Monitoring Relay Protection of 3 Phase devices against Over Voltage, Under Voltage, Single Phasing, Reverse Phasing & Unbalance Supply are the Major Issues in Electrical Systems. For The safe Running of 3-phase Devices, Special Protections That keep a Continuous Watch on Supply Conditions are very essential. The Major Cause of Maximum Load Burn-out is Overloading Which Occurs due to Unbalance Supply, Single Phasing & Reverse Phasing Conditions.

11. Light:

CFL stands for Compact Fluorescent Lamp which is an improved version of tube lights of earlier days. Like tube lights, it is a vacuum glass tube with fluorescent powder coating which is not as long and straight as tube lights but curved/twisted compact, or small in size. Like a tube light, it has electrodes or filaments at both ends. But in this case, instead of a choke, there is an electronic circuit that drives the Compact Fluorescent Lamp. Because the red wave is less in the light of the Tubelight and Compact Fluorescent Lamp, the object looks a little pale or the correct color of the object does not appear.
