Understanding how this system works is essential for safe operation. The sensors must be properly aligned and free from obstructions for the system to function correctly. Regularly inspect the sensors for damage or debris‚ and ensure they are securely mounted. If the beam is interrupted while the door is closing‚ the opener should automatically reverse.
Test the safety reversal system monthly by placing an object‚ such as a 2×4‚ in the door’s path. If the door fails to reverse upon contact‚ consult your Craftsman manual for troubleshooting steps. Do not disable or bypass the safety reversal system under any circumstances‚ as this could lead to serious injury or damage.
