Garage door sensors are vital to the functionality and safety of your garage door system. They sense if things are in the way of the door’s closing and automatically change direction to prevent accidents or damage. But similar to any mechanical or electrical appliance, over time garage door sensors can stop working, causing inconvenience and possibly creating a safety issue.
So, in this blog, we will talk about the emergency garage door sensor troubleshooting tips. Whether your garage door won’t close, it reverses when it shouldn’t or even other issues all relating to the garage door sensors, the following will help you identify and fix the problem quickly.
Check Sensor Alignment
A misaligned garage door sensor is by far the most common garage door sensor malfunction. Over time, vibrations, accidental bumps or even natural shifts in the foundation can cause the sensors to misalign. To check sensor alignment:
Check the Sensors: Make sure that there are no visible signs of misalignment (for example, if one sensor points a little higher or lower than the other sensor).
Note: Clean the sensors: Dust, dirt, or debris can interfere with sensor operation. Use a soft cloth to wipe the sensor lenses, to ensure clear visibility.
Align sensor properly: Most sensors come with alignment indicators or lights to ensure that you are adjusting them correctly. Follow the way the manufacturer says to line up the sensors.
Test Sensor Wiring
Garage door sensor problems can also result from faulty wiring. Make sure the sensor wiring is well attached to both the sensor units and the garage door opener. Inspect for any visible damage, like frayed wiring or loose connections. Repair or replace damaged wires with a manufacturer-approved procedure as needed.
Inspect for Obstructions
Sometimes the simplest answer is the right one. Check to see if anything around the garage door sensors is causing them to be triggered without reason. Common obstructions include:
- Leaves, cobwebs or other debris that cover the sensor lenses.
- Sensors being blocked by objects or vehicles in their path.
- And false readings can be caused by: Direct sunlight or reflections.
Remove all obstructions and check the garage door again to see if the problem still exists.
Test Safety Reverse Mechanism
Garage door sensors work by triggering safety reverse when they sense something in the way as the door closes. To test the safety reverse mechanism:
- Blocking the closing door with an object like a cardboard box.
- Closing the garage door from the wall-mounted control or remote.
- Check that when the door contacts the object, it stops and reverses.
A malfunctioning sensor or safety reverse sometimes needs to be professionally inspected and repaired if the door does not reverse or behaves erratically.
Account for Environmental Factors
Tyres sensors may be affected by extreme temperatures, humidity, or changing environmental conditions. If you suspect your circumstances, such as very hot or cold weather, are compromising your sensor accuracy, you can install weatherproofing seals or shields to protect the sensors from the elements.
The problems with garage door sensors can be sensitive and potentially dangerous if you ignore them.
