Understanding the Whirlpool Duet Dryer Control Board
What Is a Control Board?
The control board, often referred to as the main control board or electronic control board, is the brain of your Whirlpool Duet dryer. It is a circuit board that manages all electronic functions, including:
- Starting and stopping the dryer
- Regulating drum rotation
- Controlling temperature settings
- Managing cycle selections
- Displaying error codes and cycle information
The control board receives inputs from user interface components such as buttons, knobs, or touch panels and then sends signals to various parts of the dryer to execute the desired cycle.
Why Is the Control Board Important?
Without a functioning control board, the dryer cannot operate correctly. It ensures that the appliance runs according to selected settings and safety protocols. Malfunctions in the control board can cause issues like:
- Dryer not turning on
- Inconsistent or no heat
- Failure to respond to user inputs
- Error codes flashing on display
- Unusual noises or cycles running improperly

Common Problems Caused by a Faulty Control Board
Symptoms of a Bad Whirlpool Duet Dryer Control Board
Identifying the symptoms of a faulty control board is crucial for timely repairs. Common signs include:
- Unresponsive Controls: The buttons or touchpad do not respond when pressed.
- Cycle Errors or No Start: The dryer shows error codes or does not start at all.
- Display Issues: The digital display is blank, flickering, or shows incorrect information.
- Unusual Noises: Clicking or buzzing sounds originating from the control panel area.
- Unexpected Behavior: Dryer runs without user input, or cycles change randomly.
Common Causes of Control Board Failure
Control boards can fail over time due to various reasons:
- Power surges or electrical outages
- Moisture or humidity exposure
- Age of the appliance
- Manufacturing defects
- Internal component failure (e.g., relay, capacitor)
Understanding these causes can help in preventing future issues or in diagnosing problems accurately.
