Garage door will not close from remote but will close if wall button is held down.

Safety first: Do not continue to hold the wall button to force the door closed without resolving the sensor issue; this defeats a critical safety feature.

Steps to fix:

• Check sensor LEDs: Confirm both sensor LEDs are lit solid. If one is off or flickering, realign or repair as described in the sensor-related entries above.
• Clear beam path: Remove any objects or debris between the sensors.
• Shield from sunlight: If the problem occurs only at certain times of day, install a small shade over the sensor receiving direct sun.
• Repair wiring: Inspect and repair any damaged sensor wiring.
