Safety sensors: These components prevent accidents by keeping the door from closing when it might harm somebody, an animal, or something in its way. These sensors, installed near the bottom of the tracks on either side of your door opening, project an invisible beam that will cause a closing garage door to reverse if something obstructs it…. the sensors are misaligned, your door will not close completely and you have a home that is vulnerable as well as deficiently functioning. At Affordable Garage Door Repair, we know how important precisely aligned sensors are in order for your door to operate safely and correctly. This guide will help you perform the alignment on your own garage door sensors and also troubleshoot common issues.
1. How to Tell If Your Safety Sensors Are Out of Alignment
But first, before we get to the process of alignment what could be causing such misaligned sensors? Let us review some signs that may imply your sensor is not well-aligned:
- Door Will Not Close — The door Starts to close but turns back immediately.
- Blinking Sensor Lights: When one or both sensors show a blinking light, it means that the two of them are not aligned correctly.
- When the Opener Clicks or Beeps: This means that the opener is trying to close but due to a sensor problem, it stops.
- That the door closes and you have to hold the button down warns of a safety override: sensors should be functional but aren't working properly.
That the door closes and you have to hold the button down warns of a safety override: sensors should be functional but aren’t working
properly.
2. The Tools you will need for Sensor Alignment
- Screwdriver — to adjust the sensor brackets
- Measuring tape (to measure the alignment height)
- Zip ties (to attach sensor wires, if necessary)
- Alignment (to confirm proper sensor row)
3. How to Align Your Garage Door Safety Sensors
Below, we have included steps on how to make your sensors properly align and function correctly.
Turn Off the Power
The garage door opener must be unplugged to prevent accidents when working on the sensors.
Inspect the Sensors
Inspect these two sensors for any dust, dirt, or debris that may be causing the beam to not get through. These can be cleaned by wiping them with a damp and soft cloth. Also, check that the wiring is still glued down and connected in a good way.
Validating Sensor Placement
Setting: mount the two sensors on either side of your door, and they should be at equal height. Make sure they are straight on the tape with a measuring band. If required, adjust the brackets so they are even with the ground.
Adjust the Sensors
1:Remove all sensor bolts and tilt the brackets to relocate the sensors.
2:Adjust sensors until the indicator light on each sensor is solid (green
or amber)
3: A level will do just that; check if you leveled both sensors correctly
Test the Sensors
Once the lights are steady and sensors align, you can then use screws to lock sensor brackets.
Adjust the Sensors
Reconnect the opener to power and open & close your sensors. Place an object in the path of the beam (e.g. cardboard box) When the door is not obstructing that should be blocked immediately though.
4. Know Basic Sensor Problems and How to Resolve Them
Even if your sensors are aligned and placed at the proper distance, you may still face some common issues. Below are three problems and troubleshooting steps to help you resolve them quickly.
Problem 1: One Sensor Light Blinks and One is Solid
- Cause: Sensor is out of alignment or a physical object interfered with the beam.
- Fix: Clean the sensors, align them properly, and ensure nothing blocks the beam.
Problem 2: Sensor Lights Are Not Responsive
- Potential Problems: A malfunction or a power failure to the sensors.
- Solution: Make sure the opener is plugged in and connected to power.
Problem 3: The Door Starts to Close Then Reverses
- Reason: Sensor alignment may be slightly off or debris may be on the tracks.
- Answer: Realign the sensors and clear any obstructions from the tracks.
5. The Significance Of Correct Sensor Positioning
Keep Your Safety Sensors Aligned This is important because well-aligned safety sensors are critical to:
- Safety First: Sensors mean the door will reverse if there is something in its way, preventing accidents with people and pets.
- Continued Performance: A malfunctioned door that is misaligned due to sensors causes a lot of annoyance.
- Following Security Rules Modern garage doors are mandated to be equipped with working security sensors for safety reasons.
