Key Components and Symbols
The diagrams illustrate the connections of various electrical components, including:
- Compressor (C): The primary cooling component.
- Icemaker (IM): For automatic ice production.
- Fan Motors (M1, M2, M3): Refrigerator fan, freezer fan, and condenser fan motors.
- Heaters (R1, R2, R3, R4): Defrost heater, drain tube heater, duct heater, and frame heater.
- Switches (S1-S13): Door switches (light/fan), thermostatic controls, defrost terminator, defrost timer, overload protectors, and compressor starting relays.
- Valves (V): Icemaker water valve.
- Lights (LT, LT1, LT2): Refrigerator and freezer lights.
- Capacitors: Running and starting capacitors for compressors.
Wire colors are consistently used across diagrams, with a legend provided for each model to identify:
- BK - Black
- BL - Blue
- BR - Brown
- GR - Gray
- GN - Green
- OR - Orange
- PK - Pink

Diagram Interpretation
Each section typically includes:
- Schematic Diagram: A simplified representation of the electrical circuit, showing the flow of power and the function of each component.
- Wiring Diagram: A more detailed illustration of the actual wiring within the appliance, showing wire routing and connections to specific terminals and components.
- Legend: A key that defines the symbols used in the schematic and wiring diagrams, along with component descriptions and wire color codes.
Important Safety Note: Always disconnect the appliance from the electrical supply before performing any service or maintenance. Ensure all grounding devices are properly connected after service completion to prevent electrical shock.
General Wiring Principles
The diagrams illustrate standard 115-volt, 60-cycle AC power supply connections. Key electrical paths involve:
- Power input via the service cord (L1 and L2).
- Distribution of power through various switches and controls.
- Operation of motors (compressor, fans) and heating elements (defrost, drain).
- Control of lighting and icemaker functions.
Specific wiring configurations vary based on the model and its features, such as the presence of a freezer light or specific defrost system components.
