Understanding the fundamentals of the system’s operation and its components is crucial when fixing a garage door sensor. To stop the door from closing if there is an obstruction in its path, garage door sensors are an essential safety element. On either side of the garage door opening, these sensors are usually mounted close to the bottom of the door tracks. Across the breadth of the door opening, they release an invisible infrared beam. If an object, person, or pet blocks the beam when the door is closing, sensors will identify the obstacle and instruct the door opener to halt and reverse its motion to avoid mishaps or damage. Let’s delve into detailed instructions on repairing garage door sensors in this article.
Common Reasons Why Garage Door Sensors Stop Working
- Misalignment is one of the most common reasons why sensors malfunction. Over time, sensors may become misaligned due to vibrations from doors being opened or unintentional impacts. A misaligned sensor will cause the infrared beam it emits to break, which will cause the door to behave strangely or not close at all.
- The accumulation of dirt, dust, or debris on sensor lenses is another frequent problem. Lenses that are clogged or unclean lose their ability to detect infrared beams, which can cause false alarms or the inability to identify obstructions in the way of the door.
- Garage door sensors can also stop functioning due to wiring issues. The signal transmission between the sensors and garage door opener can be disrupted due to loose, corroded, or damaged electrical connections, which would keep the sensors and opener from successfully communicating.
Steps Involved in Fixing Broken Garage Door Sensors
The process of repairing damaged garage door sensors entails several stages to locate and resolve the underlying problems. Here’s a general how-to for diagnosing and fixing damaged sensors:
Check if the Garage Door Sensors Are Aligned
Start by visually evaluating the garage door sensors to see if they are aligned. Usually, the sensors are found close to the ground on both sides of the garage door. They ought to be square across from one another and parallel to the floor. Make sure they are horizontally aligned by using a level. Move the sensors around until they are directly facing one another if they are not aligned. To test the sensors when they have aligned, try closing the garage door using the remote opener or the wall-mounted control panel. If the sensors are placed appropriately, the door should close smoothly. If the sensors are placed appropriately, the door should close smoothly. If the door isn’t closing or the sensor warning lights are blinking, it can be a sign of misalignment or obstruction and needs more adjustment or cleaning.
Check if the Garage Door Sensors Are Dirty
To find out if the garage door sensors are dirty, look for any signs of dust, debris, or dirt buildup on the sensor lenses. Use a soft, dry cloth to gently wipe the lenses to remove any accumulated dirt or debris. Avoid using harsh chemicals or abrasive cleansers, as they can damage the lenses. After cleaning the sensor lenses, test the garage door by attempting to close it using the remote opener or wall-mounted control panel. If the sensors are dirty and blocked, the garage door should close smoothly; if not, cleaning them should solve the issue. Regular cleaning is necessary to maintain the effectiveness of the sensor lenses and ensure the garage door system functions as intended.
Check the Garage Door Sensors’ Wiring
The first step in inspecting the garage door sensor wiring is to visually assess the wiring connections between the sensors and the garage door opener motor unit. Verify that the cables are securely fastened to the terminals of the sensors and the opener unit. Watch out for any signs of damage, including rust or frayed wires, as these could indicate a problem with the wiring. If any wires are broken, replace or repair them as needed. Additionally, make sure to tighten any loose connections to ensure a solid connection. If the wiring was the issue, resolving it should resolve any sensor-related issues and guarantee a garage door closure that operates without incident.
Check the Power Supply
Make sure the garage door opener unit is receiving power before checking the power supply to the sensors. Verify that the lights are on and that the wall-mounted control panel or the remote control function operates the opener unit. If the garage door opener unit is not getting power, make sure the circuit supplying it is not tripped or blown by checking the circuit breaker or fuse box. It can be required to reset circuit breakers or change out fuses. Once the power supply to the opener unit has been confirmed, check that the wiring connections between the sensors and the opener unit are intact and firmly fastened. If the problem was with the opener unit’s power source, fixing it should take care of any sensor-related issues and allow the garage door to close smoothly.
