Components of a GE Washer Schematic
A typical GE washer schematic encompasses various components, each represented symbolically to denote their function and connection points. Understanding these components is fundamental before delving into the schematic itself.
Electrical Components
- Control Board (Main PCB): Acts as the brain of the washer, controlling cycles, motor operation, and sensor inputs.
- Wiring Harness: Connects various components, facilitating electrical flow.
- Motors:
- Drive Motor: Powers the drum for agitation and spinning.
- Pump Motor: Handles water drainage.
- Switches and Sensors:
- Door Lock Switch: Ensures safety by locking the door during operation.
- Water Level Sensor: Monitors water levels.
- Temperature Sensors: Detect water temperature.
- Cycle Selector Switch: Allows user to select washing modes.
- Heaters: Used for water heating in certain cycles.
- Fuses and Circuit Breakers: Protect the circuit from overloads.
Mechanical Components
- Drum/Basket: The main component where clothes are loaded.
- Agitator or Impeller: Moves clothes during wash cycles.
- Water Inlet Valve: Controls water flow into the washer.
- Drain Pump: Removes water post-wash.
- Drive Belt and Pulley System: Transmits motor power to drum.
How to Read a GE Washer Schematic
Interpreting a schematic effectively requires understanding the symbols, wiring conventions, and component labels used.
Symbols and Conventions
- Lines: Represent wiring; solid lines indicate direct connections.
- Dots: Show junctions where wires are connected.
- Switch Symbols: Indicate a switch's open or closed state.
- Motor Symbols: Depict different types of motors, often with arrows indicating rotation.
- Sensor Symbols: Usually shown as a resistor or thermistor.
- Ground Symbols: Indicate grounding points.
Deciphering the Diagram
1. Identify Power Supply Lines: Usually at the top or sides; often labeled L1 and N (Line and Neutral).
2. Trace Circuit Paths: Follow wiring lines from power source through switches, sensors, and control boards.
3. Locate Control Board Connections: Usually centrally positioned, showing inputs from sensors and outputs to motors and valves.
4. Understand Component Labels: Components are labeled (e.g., M1 for motor, S1 for switch), aiding in identification.
5. Follow Signal Flow: Determine how signals trigger actions, such as starting the motor when a door lock is engaged.
