Garage door sensors are crucial for safety and smooth operation. When they malfunction, your garage door may refuse to close or reverse unexpectedly. This guide will help you test and fix garage door sensors in Yarrow Point while ensuring compliance with safety standards.
1. How Garage Door Sensors Work
Garage door sensors use infrared beams to detect obstacles:
- Photoelectric Sensors: Emit an invisible beam that triggers the door to stop and reverse if interrupted.
- Safety Mechanism: Prevents accidents by ensuring the garage door only closes when the path is clear.
