Technician Note
Timer-to-Close is a useful feature only when the opener is designed for it and the safety sensors are aligned and reliable. If the door has sensor errors, do not use the timed close feature.

- Verify the opener has properly installed and aligned photoelectric safety sensors.
- Check that Timer-to-Close is allowed on the specific opener model.
- Confirm the existing wall control wiring is intact.
- Match the part number to the opener manual or replacement parts diagram.
Professional Advisory
Do not enable timed closing on a door with missing safety devices, intermittent sensor faults, or poor door balance. A qualified garage door technician should correct those issues first.
