How to Fix Garage Door Sensor
Garage door sensors ensure the safety and durability of automatic garage doors while enhancing convenience. Introduced in the U.S. in 1993, the initial two-component optical sensors prevented doors from closing if an obstacle, like a person or a car, was detected underneath. These sensors are crucial for reducing injury risk and preventing vehicle damage, making them an essential component of modern garage door systems.
Such sensors are an important element of a garage door, as they reduce the risk of injury to a person and damage to the car.
Common Garage Door Sensor Problems
One key indicator of sensor issues is improper operation. If the garage door fails to open or close or doesn't respond consistently, it likely points to a sensor problem. Other symptoms might include the door reversing unexpectedly or the sensors' lights flashing. Regular maintenance and alignment checks can prevent these issues and ensure the reliable operation of your garage door system.
Interference Near the Sensor
One common cause of garage door sensor issues is interference. The transmitter and receiver sensors are typically located near the ground on opposite sides of the garage door repair. If the door won't close, something may be obstructing one of the sensors, or one of the sensors may have shifted out of alignment. In either case, the light beam is interrupted, preventing it from traveling straight from the transmitter to the receiver.
Dirty Sensor Lenses
Dirt and spider webs often accumulate on the sensor lenses over time, blocking the transmitter or receiver. To clean them, use a soft microfiber cloth to remove all debris gently. Be careful not to scratch the lenses. Once thoroughly cleaned, the sensors should function appropriately if dirt is the issue. Regular cleaning can help maintain optimal sensor performance.
Deformed Sensor Mount
A common issue with garage door sensors is a deformed sensor mount. Since the frame is often made of aluminum, it can quickly become bent. When the mount is deformed, the light beam cannot pass correctly from the transmitter to the receiver. This deformation can occur accidentally when someone kicks the sensor or hits it with a bicycle while leaving the garage. Regularly checking and adjusting the sensor mounts can help maintain proper alignment and function.
Moisture Inside the Sensor
Moisture inside the sensor can disrupt its function, often due to rain exposure. It’s best to wait for the moisture to dry before cleaning the sensor with a soft microfiber cloth. Sensors are susceptible and should be checked periodically to ensure proper operation. Regular maintenance can prevent sensor failure, which is crucial for the overall functionality of the garage door and to avoid potential injury or damage to your vehicle. Ensuring your dry and clean sensors will help maintain a safe and reliable garage door system.
