Garage Door Sensor Repair Sunnyside

Is your garage door acting up, refusing to close, or reversing unexpectedly? The culprit might be faulty garage door safety sensors. At Garage Door Repair Sunnyside, our skilled technicians are experts in diagnosing and repairing all types of garage door sensor problems. With our same-day service and commitment to fair prices, you can trust us to get your automatic garage back in working order quickly and efficiently.

Types of Garage Door Sensors

There are several types of garage door sensors, each designed to ensure the safe operation of your garage door:

Reed Switch Door Sensor

Reed switch door sensors consist of a magnet and a reed switch. The magnet is attached to the garage door, while the reed switch is mounted on the door frame. When the door is closed, the magnet aligns with the reed switch, creating a closed circuit. If the door is open, the circuit is broken, and the sensor communicates this to the opener. Reed switch sensors are ideal for detecting when the garage door is fully closed and are durable and long-lasting, as there are no moving parts. However, they are not suitable for detecting obstructions in the doorway.

Infrared Door Sensor (Photo Eyes)

Infrared door sensors, also known as photo eyes, use an infrared beam to detect obstructions in the doorway. They consist of two parts: an emitter and a receiver. The emitter sends an infrared beam across the doorway to the receiver. If an object breaks the beam, the receiver signals the opener to stop or reverse the door. Infrared sensors are required by law on all garage door openers manufactured after 1993 and are mounted on either side of the doorway, typically 4-6 inches above the ground. They ensure the safety of people and objects in the doorway but require proper alignment and clean lenses to function correctly. Infrared sensors are vulnerable to damage from moisture, dirt, and physical impact.

Rolling Switch Door Sensor

Rolling switch door sensors are mounted on the garage door track and consist of a switch and a lever or wheel that rolls along the track. When the door is fully closed, the lever or wheel presses against the switch, creating a closed circuit. If the door is open, the circuit is broken, and the sensor communicates this to the opener. Rolling switch sensors detect when the garage door is fully closed and are more compact and less visible than reed switch sensors. However, they can be prone to wear and tear due to moving parts and are not suitable for detecting obstructions in the doorway.

At Garage Door Repair Sunnyside, we work with trusted brands like Chamberlain, Genie, Liftmaster, Garage Stop, and Digi-Code to ensure your garage door sensors are repaired with quality parts.
