The True GDM-72 is a popular commercial refrigerator, used in many restaurants and food service establishments. As with any appliance, it is important to understand the wiring diagram in order to properly diagnose and repair any issues that may arise. This article will provide a comprehensive guide to the True GDM-72 wiring diagram, including tables and frequently asked questions.
Overview of the True GDM-72 Refrigerator
The True GDM-72 is a three-section glass door refrigerator with a capacity of 72 cubic feet. It is designed for use in commercial environments and features a stainless steel exterior, energy-efficient glass doors, and LED lighting. The unit is equipped with a bottom-mounted compressor for easy access and maintenance.
Understanding the wiring diagram of the True GDM-72 is essential for maintaining the proper operation of the unit. The wiring diagram illustrates the electrical components and connections of the refrigerator, including the compressor, fan motors, defrost timer, and temperature controls.
Compressor Wiring
The compressor is the heart of the refrigeration system and is responsible for circulating the refrigerant through the system. The wiring diagram for the compressor includes the power supply, start capacitor, run capacitor, and overload protector. The power supply wires connect to the line voltage, which is typically 115 volts for commercial refrigerators. The start capacitor provides a boost of energy to the compressor during startup, while the run capacitor maintains the electrical charge to keep the compressor running smoothly. The overload protector is a safety device that shuts off the compressor if it overheats or experiences a mechanical failure.
It is important to note that the wiring diagram for the compressor may vary depending on the specific model of the True GDM-72 refrigerator. Refer to the manufacturer’s documentation for the correct wiring diagram for your unit.
Fan Motor Wiring
The True GDM-72 has multiple fan motors that are responsible for circulating air throughout the refrigerator to maintain a consistent temperature. The wiring diagram for the fan motors includes the power supply, starting capacitor, and run capacitor. The power supply wires connect to the line voltage, while the starting and run capacitors provide the necessary electrical charge to start and maintain the motor operation.
Defrost Timer Wiring
The defrost timer is an essential component of the True GDM-72 refrigerator, responsible for defrosting the evaporator coils to prevent ice buildup. The defrost timer wiring diagram includes the power supply, timer motor, and defrost termination switch. When the defrost timer activates, the timer motor advances the timer mechanism, which turns off the compressor and fan motors and activates the defrost heaters. The defrost termination switch senses the temperature of the evaporator coils and terminates the defrost cycle once they reach a certain temperature.
