Opener lights flash 10 times and door will not close from remote; will close only when holding wall button; red STATUS LED may show beam error pattern.

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

Steps:

• Clear the path: Remove any objects, tools, or debris near the bottom of the door that could block the beam.
• Clean lenses: Gently wipe each sensor lens with a soft, dry cloth to remove dust, cobwebs, or moisture.
• Check alignment: Verify both sensor LEDs are lit solid. Adjust until the receiver LED (usually green) is steady, not flickering.
• Shield from sun: If direct sunlight hits the receiver, temporarily shade it and test. If this resolves the issue, consider installing a sun shield or slightly angling the sensor.
• Retest closing: Use the remote to close the door. The lights should not flash 10 times if the beam is clear and aligned.
