What Is a Whirlpool Control Board?
Definition and Purpose
A Whirlpool control board is an electronic circuit board that acts as the brain of the appliance. It receives input from various sensors, buttons, and dials, processes this data, and then sends commands to different components such as motors, valves, heaters, and lights. Its primary goal is to ensure that the appliance operates according to the selected cycle or setting, maintaining safety, efficiency, and user convenience.
Components of a Control Board
- Microcontroller or Microprocessor: The main unit that processes signals and executes commands.
- Relays and Switches: To turn on/off components like heating elements or motors.
- Connectors and Terminals: For wiring inputs and outputs.
- Sensors: Temperature, water level, voltage, or current sensors that provide real-time data.
- Display Modules: LCD or LED screens that show cycle status and error codes.
- Input Interfaces: Buttons, dials, or touchscreens for user commands.
Types of Whirlpool Control Boards
Based on Appliance Type
Different appliances require specific control boards tailored to their functions. Common types include:
- Washer Control Boards: Manage wash cycles, water levels, spin speeds, and temperature settings.
- Dishwasher Control Boards: Control wash cycles, water flow, heating, and drying functions.
- Range and Oven Control Boards: Regulate temperature, cooking modes, timers, and safety features.
- Refrigerator Control Boards: Handle temperature regulation, defrost cycles, ice maker operation, and display functions.
Based on Technology
Control boards also differ based on technological sophistication:
- Analog Control Boards: Use simple circuits with knobs and switches; less common today.
- Digital Control Boards: Incorporate microprocessors, allowing for advanced features and diagnostics.
- Smart Control Boards: Compatible with Wi-Fi or Bluetooth, enabling remote control and diagnostics via smartphone apps.
