Garage door starts to close then immediately reverses and the Ryobi opener light flashes, but no code is shown.

Safety first: Never bypass or tape over safety sensors. They are required for safe operation.

• 1. Clean lenses: Gently wipe both sensor lenses with a soft cloth. Remove cobwebs and dust from around the brackets.
• 2. Check LEDs: Confirm both sensors show solid indicator lights. If one is off or blinking, adjust alignment until both are solid.
• 3. Shield from sunlight: If direct sun hits a sensor, create a small shade using a non-metallic cover or slightly rotate the sensor within alignment limits.
• 4. Inspect wiring: Follow the sensor wires back to the opener, looking for damage. Repair or replace any crushed or cut sections.
