Safety Precautions
CRITICAL SAFETY STEPS BEFORE BEGINNING:

Step-by-Step Replacement Guide for W10303820
Access the Control Board
For models using the W10303820 control board:
- For top-load models: Locate and remove the two screws at the back of the control panel. Then carefully slide a putty knife under the control panel to release the retention clips.
- For front-load models: Remove the top panel by inserting a flat tool (putty knife or flat screwdriver) into the seam at the front corners and gently lifting to release the clips.
Once you’ve gained access, locate the main control board. For the W10303820, it’s typically housed in a plastic enclosure inside the control panel assembly.
Document & Disconnect Wiring
Before removing any wires:
- Take a clear photo of the current wiring configuration with your smartphone
- Label each wire harness with masking tape and a marker (e.g., “P1,” “P2,” etc.)
- Disconnect one wire at a time by pressing the locking tabs on the harnesses and gently pulling
- Be especially careful with ribbon cables, which are more delicate than standard wire harnesses
Pro Tip: Never pull directly on the wires themselves, only on the plastic connector housings. Pulling on wires can damage connections and lead to further problems.
Remove the Old Board
- Locate the 4 mounting screws securing the W10303820 board to the control panel housing
- Carefully remove these screws and set them aside in your parts container
- Note the orientation of the board before removing it completely
- Gently lift the board straight out to avoid bending any pins or components
- Place the old board on a non-conductive surface
Examine the old board for any visible damage like burnt components, bulging capacitors, or corrosion, which can help confirm your diagnosis.
Install the New W10303820 Board
- Remove the new W10303820 control board from its packaging
- Handle it only by the edges to prevent static damage
- Align the new board with the screw holes in the control panel housing
- Insert and tighten the 4 mounting screws, being careful not to overtighten
- Reconnect all wiring harnesses according to your labels and photo reference
- Ensure each connector clicks securely into place
- Double-check that any ribbon cables are fully inserted and secured
Reassemble and Test
- Snap the control panel back into place (or reattach with screws, depending on your model)
- Ensure all clips engage properly and the panel sits flush
- Plug in the washer and wait 30 seconds for the control board to initialize
- Run a calibration cycle (usually done by pressing a specific button combination—check your washer’s manual)
- Test all washer functions, including each cycle setting
Success Indicator: A properly installed W10303820 control board will result in a washer that powers up normally, responds to all controls, and completes cycles without error codes. Listen for normal clicking sounds as the control board activates various washer functions.
Troubleshooting Post-Installation
If Your Washer Is Still Not Working:
Washer Completely Dead
- Check your home’s circuit breaker
- Verify the 15A internal fuse on the control board
- Test the power outlet with another appliance
- Inspect the power cord for damage
Error Codes Still Appearing
- Reset the washer by unplugging it for one full minute
- Check door latch assembly (common issue with front-loaders)
- Verify all wire connections are secure
- Test water inlet valves for continuity
Partial Functionality
- Some functions work but others don’t? This usually indicates a connection issue
- Re-check all wire harness connections
- Examine the user interface cable for proper connection
- Test individual components (motor, pump, valves)

Frequently Asked Questions
No, Whirlpool washer control boards are not interchangeable. Using a mismatched board (even one with a similar appearance or from a similar model) can damage your washer and potentially create safety hazards. The W10303820 board is specifically designed for particular Whirlpool models, and substituting it with a different part number will likely result in communication errors between components.
While technically possible, repairing a W10303820 control board requires specialized equipment and advanced electronics knowledge. Common failures involve surface-mount components, microcontrollers, or damaged traces that are extremely difficult to repair without professional tools. For most homeowners, replacement is more cost-effective and reliable than attempting repairs.
A W10303820 control board typically lasts 7-10 years under normal usage conditions. Factors that can reduce lifespan include power surges, exposure to moisture or extreme temperatures, and heavy usage patterns. OEM boards generally last longer than aftermarket alternatives. With proper care and maintenance, your replacement board should provide years of reliable service.
For washers less than 7-8 years old, replacing the W10303820 control board is usually cost-effective. The replacement costs approximately $160-270 while a new comparable washer starts at $600-800. However, if your washer has multiple issues beyond the control board or is over 10 years old, replacement might be more economical in the long run. Consider the washer’s overall condition, age, and the availability of other parts before investing in a control board replacement.
When to Call a Professional
While replacing a W10303820 control board is achievable for many DIYers, certain situations warrant professional help:
- If you notice frayed wiring or damaged connectors
- When capacitors appear swollen or leaking
- If burning smells persist after board replacement
- When multiple components have failed simultaneously
- If you’re uncomfortable working with electrical components
A professional technician will have the tools and expertise to diagnose complex issues beyond a simple board failure.
