Understanding the Whirlpool Control Board
What Is a Control Board?
The control board, often called the electronic control module or main control board, is an essential component in modern Whirlpool appliances. It is a printed circuit board (PCB) that houses microprocessors, relays, and other electronic components. The control board interprets user inputs from the keypad or touch panel and sends signals to various parts of the appliance, such as the motor, water inlet valve, or heating element.
Types of Control Boards in Whirlpool Appliances
Whirlpool appliances may use different control boards depending on the model and age:
- Main Control Board: Coordinates overall operation.
- User Interface Board: Handles user input and display.
- Display Board: Manages the visual interface.
- Power Control Board: Distributes power to different components.
Modern models often integrate these functions into a single main control board.
Reasons for Control Board Failure
Understanding the common causes of control board failure can help prevent future issues and determine if replacement is necessary.
Common Causes
- Power surges or voltage fluctuations: Sudden spikes can damage electronic components.
- Moisture exposure: Water or humidity can cause corrosion or short circuits.
- Age and wear: Over time, components can degrade.
- Faulty wiring or connections: Loose or damaged wires can cause electrical problems.
- Component failure: Microprocessors or relays may fail due to manufacturing defects or stress.
Symptoms of a Faulty Control Board
- The appliance does not respond to control inputs.
- Error codes display on the user interface.
- The appliance cycles unpredictably or stops mid-cycle.
- Unusual noises or burning smells from the control panel area.
- The appliance refuses to start or complete cycles.
Diagnosing the Need for Control Board Replacement
Initial Troubleshooting Steps
Before replacing the control board, perform these checks:
- Reset the appliance: Unplug it for 1-2 minutes and plug back in.
- Inspect the wiring: Look for loose, burnt, or damaged wires.
- Check for error codes: Refer to the user manual for code meanings.
- Test other components: Ensure motors, switches, and sensors are functioning.
When to Replace the Control Board
Replace the control board if:
- Error codes persist after troubleshooting.
- The appliance is unresponsive to controls.
- There are visible signs of damage on the board (burn marks, corrosion).
- The appliance exhibits electrical issues that cannot be traced to other parts.
Tools and Materials Needed for Replacement
Gather the following before starting:
- Phillips and flat-head screwdrivers
- Multimeter (for testing electrical continuity)
- Replacement Whirlpool control board compatible with your model
- Gloves and safety glasses
- Owner’s manual or service sheet for your appliance model

3. Reassemble the Control Panel
- Reattach the control panel cover.
- Secure with screws.
4. Test the Appliance
- Plug the appliance back into the power outlet.
- Turn on and run a test cycle to verify proper operation.
Testing and Troubleshooting After Replacement
- Observe if the appliance responds correctly to control inputs.
- Check for error codes or abnormal behavior.
- Use the multimeter to verify voltage and continuity on the new control board if issues persist.
- If problems continue, revisit wiring connections or consider consulting a professional technician.
Additional Tips for a Successful Replacement
- Always use genuine or OEM replacement parts for compatibility and reliability.
- Keep track of screws and small parts during disassembly.
- Follow manufacturer instructions specific to your appliance model.
- If unsure about electrical testing, seek professional assistance.
- Consider replacing other worn components, such as door switches or sensors, simultaneously if they are suspect.
Cost Considerations and When to Seek Professional Help
- Cost of Replacement Control Board: Ranges from $100 to $300 depending on the model.
- Labor Costs: Professional repair may add $100–$200.
- When to Call a Technician:
- If you are uncomfortable working with electrical components.
- When the replacement does not resolve the issue.
- If you suspect underlying wiring or circuit problems.
Preventive Measures to Extend the Life of Your Control Board
- Use surge protectors to guard against voltage spikes.
- Keep the appliance in a dry, well-ventilated area.
- Regularly inspect wiring and connections.
- Avoid overloading the appliance.
- Schedule periodic professional maintenance.
