Experiencing washer issues? The 49TYZ 110 actuator could be the culprit. This comprehensive guide explains what this critical component does, how to identify when it’s failing, and provides a detailed replacement process to get your Whirlpool, Kenmore, Maytag, or Amana top-load washing machine running smoothly again.
What is the 49TYZ 110 Washer Switch Actuator?
The 49TYZ 110 is a vital component in many top-loading washing machines that controls the lid lock mechanism and manages cycle transitions. This small but powerful device ensures your washer operates safely by preventing the lid from opening during operation and coordinating motor shifts between wash, spin, and drain cycles.
Located under the washer’s top console near the motor and transmission, this actuator is the brain behind your washer’s mechanical operations. When functioning properly, you’ll never notice it, but when it fails, your entire washing machine can stop working.

Signs of a Failing 49TYZ 110 Actuator
Recognizing the symptoms of a failing actuator can save you time and money. Here are the telltale signs that your 49TYZ 110 might need replacement:
Warning Signs
- Machine won’t start or complete cycles – The washer fails to begin washing or stops mid-cycle
- Error codes appear – Particularly F5/E1 or F7/E3 codes, which directly relate to actuator issues
- Unusual clicking noises – Repetitive clicking during cycle transitions
- Spin cycle failure – Washer fills with water but doesn’t agitate or spin
- Inconsistent operation – Machine works sometimes but fails at other times
If you’re experiencing any of these symptoms, it’s highly likely that your 49TYZ 110 actuator needs replacement. The good news is that this is a repair you can handle yourself with the right guidance.
Safety Precautions Before Beginning Repair
⚠️ Important Safety Alert
Working with electrical appliances can be dangerous. Always follow these safety steps before attempting any repairs:
- Unplug the washer from the electrical outlet to eliminate shock hazards
- Discharge residual power by pressing the start button after unplugging
- Turn off the water supply to prevent potential water damage
- Allow the machine to cool if it has been running recently
- Work in a well-lit area to ensure you can see all components clearly
Note: Never attempt to repair your washer while it’s plugged in or while there’s water in the tub.

- Small container for screws
Step-by-Step 49TYZ 110 Replacement Guide
Follow this detailed guide to replace your washer’s actuator with confidence:
Access the Actuator
Carefully tilt the washer backward onto a padded surface to expose the underside. This may require assistance as washers are heavy. Remove the belt guard using a 5/16″ nut driver to access the internal components.
Disconnect Wiring
Locate the actuator’s modular power connector. Gently unplug it by pressing the release tab and pulling straight out. Never pull on the wires themselves as this can damage the connections.
Remove the Old Actuator
Unscrew the two Phillips-head screws securing the actuator to the washer frame. Carefully wiggle the actuator to release it from the shift lever. The actuator connects to the transmission through a pin mechanism, so gentle manipulation may be required.
Install the New Actuator
Align the new 49TYZ 110 actuator’s pin with the shift lever’s socket. Make sure the orientation matches the original installation. Secure the new actuator with the two Phillips screws, being careful not to overtighten. Reconnect the wiring harness, ensuring it clicks into place.
Reassemble and Test
Replace the belt guard and secure it with the appropriate screws. Carefully return the washer to an upright position. Plug in the washer and run a short test cycle to ensure proper operation before performing a full load.
Pro Tips for a Successful Repair
- Take photos before disconnecting components to reference during reassembly
- Keep track of all screws and small parts in a labeled container
- Test the washer with an empty load first to confirm proper operation
- Listen for unusual noises during the test cycle that might indicate improper installation
Troubleshooting Post-Replacement Issues
Even with a successful replacement, you may encounter some issues. Here’s how to troubleshoot common problems after installing a new 49TYZ 110 actuator:
| Issue | Possible Cause | Solution |
|---|---|---|
| Washer still won’t start | Disconnected wiring or faulty lid lock | Check all electrical connections and inspect the lid lock assembly |
| Error codes persist | Control board needs reset or actuator is incompatible | Unplug washer for 1 minute to reset; verify part compatibility |
| Unusual noises during operation | Actuator not properly aligned with shift lever | Reinstall actuator, ensuring proper alignment with the shift mechanism |
| Intermittent operation | Loose wiring connection | Check and secure all electrical connections |
When to Call a Professional
If you’ve replaced the actuator and continue to experience issues, it may indicate a more complex problem with your washer’s control board or wiring harness. In these cases, consulting with a professional appliance technician is recommended.
OEM vs. Aftermarket 49TYZ 110 Parts
OEM Parts
Advantages:
- Exact match to original specifications
- Typically higher quality materials
- Better reliability and longer lifespan
- May come with manufacturer warranty
Disadvantages:
- Higher cost (typically $20-40 more)
- May have longer shipping times
Aftermarket Parts
Advantages:
- Lower cost
- Often more readily available
- May include additional features or improvements
Disadvantages:
- Variable quality control
- Potential fit issues
- Typically shorter lifespan
- May void manufacturer warranty on other components
Recommendation
For critical components like the 49TYZ 110 actuator, investing in OEM parts generally provides better long-term value despite the higher initial cost. The improved reliability and longer service life typically offset the price difference, especially when considering the labor involved in repeated replacements.
Preventative Maintenance Tips
Extend the life of your new 49TYZ 110 actuator and prevent premature failure with these maintenance practices:
- Regular lid lock cleaning – Monthly cleaning of the lid latch mechanism prevents buildup that can strain the actuator
- Avoid overloading – Excessive weight puts undue stress on all washer components, including the actuator
- Run diagnostic cycles – Many modern washers have built-in diagnostic modes that can identify issues before they cause complete failure
- Check wiring connections – Periodically inspect for loose or damaged wiring that could affect actuator performance
- Address unusual noises promptly – Clicking or grinding sounds can indicate developing problems
“An ounce of prevention is worth a pound of repair. Regular maintenance not only extends the life of your actuator but also improves the overall performance and efficiency of your washing machine.”
