How Do I Disable the ANSO Feature on the Triple-Chime Clock Kit GFKIT1?
If you’re using the GFKIT1 Triple-Chime Clock Kit from Clockworks.com, you may have encountered the ANSO feature and wondered how to turn it off. ANSO—short for Automatic Night Shut-Off—is designed to silence your clock’s chimes automatically during nighttime hours. While helpful for many, it’s not always desirable for every setup. Disabling it is possible, and in this guide, we walk you through how to turn off ANSO on your GFKIT1 movement safely and correctly.
Let’s answer your questions and walk through the process step-by-step.
What Is the ANSO Feature?
The Automatic Night Shut-Off (ANSO) feature on the GFKIT1 movement ensures the clock remains silent during preset nighttime hours—typically from around 10 PM to 6 AM. This automatic silencing helps users avoid chime disturbances while sleeping.
For customers who prefer to hear their clock chime all day and night—or who use the movement in a location where silencing is not needed—this feature may feel more like a limitation than a benefit.
Can I Disable the ANSO Feature Myself?
Yes, you can disable the ANSO function manually without damaging your movement. The procedure is straightforward but requires care and attention. Clockworks.com recommends doing this during daylight hours when the movement is not in its “silent” phase to avoid misalignment or gear tension issues.
What Tools Will I Need?
- A clean, padded work surface
- Small flat-head screwdriver
- Steady hands and good lighting
- Optional: magnifying glass for close-up work
Where Is the ANSO Lever Located?
The ANSO lever is typically located on the back or side of the movement, depending on the generation of the GFKIT1. It’s a small metal or plastic tab that interacts with the internal cam that controls night silencing.
Locate the backplate of your movement. Look near the gear trains for a narrow, notched lever labeled or positioned adjacent to the words “NIGHT SHUTOFF” or similar. You may also see a small notch in the cam that engages with this lever during the ANSO cycle.
Step-by-Step: How to Disable ANSO on the GFKIT1
- Remove the Movement Safely
Unplug any power source if it’s electric. If it’s a mechanical unit, stop the pendulum to pause the gear train. Remove the movement from the case carefully and place it dial-down on your padded surface.
- Locate the ANSO Lever
Find the ANSO lever as described above. You may need to gently rotate the cam gear with your hand to see how the lever engages with it during the 10 PM to 6 AM range.
- Slide or Bend the Lever
Depending on your GFKIT1 version, either:
Caution: Do not force or snap the lever. If resistance feels tight, stop and reassess the movement orientation. Forcing the part may break it.
- Slide the lever out of engagement range (some have a track or guide).
- Or gently bend the lever so it no longer makes contact with the shutoff cam.
- Test the Movement
Rotate the time manually using the minute hand to simulate the 10 PM – 6 AM window. If the chime continues to function normally during that time, the ANSO has been successfully disabled.
- Reinstall and Monitor
Carefully reinstall the movement. Rehang the pendulum, set the time, and monitor the chimes overnight to confirm the change was successful.
What If I Change My Mind Later?
You can always reactivate the ANSO feature by returning the lever to its original position. If you bent it out of range, gently reshape it using small pliers. Always do this slowly to avoid metal fatigue or breaking plastic components.
Does Disabling ANSO Affect Clock Performance?
No, turning off ANSO does not interfere with timekeeping or chime accuracy. The only effect is that your clock will chime continuously across the 24-hour cycle. That said, always test your movement thoroughly after making changes.
Are All Triple-Chime Kits the Same?
Not quite. While most triple-chime movements have a similar ANSO mechanism, GFKIT1 is unique in its design and layout. Always refer to product-specific guides like this one when adjusting features.
If you’re unsure whether you have the correct kit, look for your original product label or match your movement to the images and specs listed on [Clockworks.com]() where the GFKIT1 Triple-Chime Clock Kit is available for purchase.
Final Tips for Working on Your Clock Kit
- Always work on a non-static surface and avoid touching internal gears unnecessarily.
- Wash your hands before handling parts to avoid transferring oils or debris.
- Never disassemble the movement unless you’re trained in horological repair.
