Door will not close from remote; will only close if wall button is held down continuously.

This behavior is a safety override indicating the sensors are not seeing each other.

• 1. Check sensor LEDs: Ensure both Sommer photo eyes show solid LEDs when the door opening is clear.
• 2. Realign sensors: Adjust each sensor until both LEDs are solid. Tighten brackets carefully.
• 3. Inspect wiring: Repair any damaged low‑voltage wires and ensure correct polarity at the opener terminals.
• 4. Shade from sunlight: If direct sun hits a sensor, install a small shade or reposition slightly while maintaining alignment.
