If your washing machine is acting up and you suspect that the control board may be the culprit, you’re in the right place. In this comprehensive guide, I will walk you through the process of determining whether your washing machine control board is bad or not.
We’ll cover the signs of a malfunctioning control board, how to test it, and even the cost of replacement. Let’s jump right in and restore the optimal functionality of your washing machine!
What is a Washing Machine Control Board and What Does it Do?
The washing machine control board is a crucial component that regulates the various functions of your washing machine. It acts as the brain of the machine, receiving signals from sensors that measure factors such as water temperature, spin speed, and pressure.
Based on these inputs, the control board sends commands to the motor, drum, and agitator to carry out the desired actions during the wash cycle.
In top-load washing machines, the control board is typically located in the top control panel, while in front-load washers, it is situated behind the control pad in the front.
The control board controls components such as the drain pump, tachometer, temperature sensor, water inlet valves, pressure switch, water level sensor, motor, lid lock, and power capacitor.

Signs of a Bad Washing Machine Control Board
Identifying the signs of a malfunctioning control board can help you determine whether it needs to be replaced. Here are some common indicators that your washing machine control board may be bad:
- The washing machine fails to start when turned on, even when plugged in.
- None of the buttons on the control panel respond when pressed, or the machine shuts off immediately after starting.
- The spin cycle does not initiate.
- All or some of the lights on the control panel blink alternately.
- The washing machine does not stop at the set time and continues the cycle indefinitely.
- Specific wash options or programs do not function.
- The drum or tub does not spin or spin at an abnormally slow speed.
- The machine displays an error code indicating a faulty control board.
- The washing machine either does not drain water or drains when not set to do so.
How to Test a Washing Machine Control Board
Testing the control board is an essential step in diagnosing whether it is the cause of your washing machine’s problems. While it can be challenging to test and repair a control board, you can perform a basic test using a multimeter. Here’s how to proceed:
- Locate the control board: Depending on the type of washing machine, the control board is typically found either in the top control panel or behind the control pad in the front.
- Use a multimeter: Set your multimeter to measure continuity and carefully test the terminals on the control board.
- Check for continuity: Place the multimeter probes on the terminals of the control board and observe the reading. If there is continuity, it indicates that the control board is likely functioning correctly. If there is no continuity, it suggests a problem with the control board.
- Consider professional assistance: If you have determined that the control board is faulty, it is recommended to seek the help of a professional appliance repair technician for further diagnosis and repair.
How to Replace the Control Board on a Washing Machine
If testing confirms that your washing machine control board is indeed defective, you may need to replace it. While replacing a control board can be a complex task, here is a general overview of the steps involved:
- Disconnect the power: Ensure that the washing machine is unplugged and disconnected from the power source to avoid any electrical hazards.
- Access the control board: Depending on your washing machine model, you may need to remove the top control panel or front control pad to access the control board.
- Remove the old control board: Carefully disconnect any wiring harnesses or connectors attached to the control board and unscrew it from its mounting location.
- Install the new control board: Align the new control board and securely fasten it in place. Reconnect any wiring harnesses or connectors that were disconnected.
- Reassemble the washing machine: Put the control panel or control pad back in place and ensure that all screws and fasteners are securely tightened.
- Test the new control board: Plug in the washing machine and perform a test run to verify that the new control board is functioning correctly.
Cost of Replacing a Washer Control Board
The cost of replacing a washer control board can vary depending on factors such as the brand and model of the washing machine, the extent of the damage, and the price of new components.
In general, the cost of a control board can range from $99 to $250. However, it is worth noting that replacing a control board can be a complex process that requires specialized expertise and equipment. Therefore, it is often more cost-effective to hire a professional appliance repair service to handle the replacement.
A malfunctioning washing machine control board can cause various issues, from the machine not starting to erratic behavior during the wash cycle. By familiarizing yourself with the signs of a bad control board and learning how to test it, you can quickly diagnose the problem and take appropriate action.
Whether you choose to replace the control board yourself or seek professional assistance, restoring the functionality of your washing machine will ensure that your laundry routine runs smoothly.
FAQ about How to Tell if Your Washing Machine Control Board is Bad
How can I tell if my washing machine control board is bad using a multimeter?
To test the control board with a multimeter, locate the board, and check for continuity between the terminals using the multimeter probes. If there is continuity, the control board is likely functioning correctly. If there is no continuity, it indicates a problem with the control board.
Can a washing machine control board be repaired?
In some cases, control boards can be repaired or remanufactured to restore their functionality. However, in most cases, it is more practical and cost-effective to replace the control board altogether.
What causes control board failure in washing machines?
Control board failures can be caused by various factors, including environmental conditions, aging, and manufacturing defects. While control board failures are relatively uncommon, they can occur either during initial use or after years of operation.
Remember, if you encounter any difficulties during the testing or replacement process, it is best to consult a professional appliance repair technician to ensure proper diagnosis and repair.
