As a homeowner, maintaining and checking your garage door is crucial. Ensuring your garage door sensor is working correctly is a big part of this maintenance. But how do you know if the sensor is bad? In this article, we will provide you with some big terrific tips to help you understand if your garage door sensor is malfunctioning.
What is a Garage Door Sensor?
A garage door sensor is a small device that plays a big role in the safe operation of your garage door. It is usually located at the bottom of your garage door tracks and is responsible for detecting any obstructions in the path of the garage door. If something is detected, the sensor ensures that the door doesn’t close, preventing accidents and injuries.
Signs of a Bad Garage Door Sensor
Here are some signs that your garage door sensor might be bad:
1. The Garage Door Won’t Close
If your garage door refuses to close, it could be due to a bad sensor. When the sensor isn’t working correctly, it may mistakenly detect an obstruction and prevent the door from closing.
2. Intermittent Operation
An intermittent garage door operation can indicate a sensor issue. If your door works sometimes and not others, it may be a sign that your sensor is failing.
3. Blinking Sensor Lights
Most garage door sensors have indicator lights. If these lights are blinking or not illuminated at all, it could be a sign that the sensor is malfunctioning.
4. Misaligned Sensors
Garage door sensors need to be aligned perfectly to work correctly. If one of the sensors is misaligned, the door won’t operate properly.
How to Test Your Garage Door Sensor
Testing your garage door sensor is a simple process that you can do yourself. Here’s how:
1. Check the Alignment
Ensure that both sensors are facing each other directly. If they’re not, adjust them until they are.
2. Inspect the Wires
Inspect the wires leading to the sensors for any signs of damage. If the wires are frayed or broken, you may need to replace them.
3. Clean the Sensors
Dirt and debris can obstruct the sensors. Use a soft cloth to clean the sensor lenses.
4. Test the Obstruction
Place an object in the path of the door and try to close it. If the door stops closing and reverses, the sensor is working correctly.
When to Call a Professional
If you’ve tested your sensors and they still seem to be malfunctioning, it may be time to call a professional. A technician can diagnose the problem and recommend the best course of action. If you are facing other issues like a garage door that wont open or has become noisy, you may find this info helpful.
Benefits of Professional Inspection
Having a professional inspect your garage door sensors has several advantages:
- Accurate diagnosis of the problem
- Proper repair or replacement of the sensors
- Ensuring the safe operation of your garage door
Preventive Maintenance Tips
Regular maintenance can help prevent sensor issues. Here are some tips:
1. Regular Cleaning
Clean the sensor lenses regularly to avoid dirt and debris build-up.
2. Check Alignment
Periodically check the alignment of the sensors to ensure they are facing each other properly.
3. Inspect Wires
