There are plenty of names and models of garage door openers for all garage use.
The purpose of the garage door sensor is to keep the garage door from closing down on any obstruction.
It’s the safety measure that saves your random objects or pets from getting hurt from the garage door.
Its purpose adds a layer of protection to your garage.
However, the function can sometimes turn into a nuisance.
Imagine your garage door not closing down at all despite not having any distractions in the way.
You can’t allow your garage door to be open all night for invasions and home threats.
Instead of protecting your home, it does the opposite, giving you a very vulnerable garage.
The issue of the garage door that doesn’t close down comes from the alignment of the sensors.
Sensors, also more commonly known as photoelectric sensors or the photo eyes of the garage, need proper alignment to work.
They signal the door not to close down because the blockage in the path causes the light beam not to reach the other sensor.
If you have a broken beam of light, the garage door thinks that something is standing in the way.
Align the garage door sensors
Prepare some tools before adjusting the alignment of the sensors.
Be sure to get these items first before starting the work.
Then, apply the simple steps on how to align Chamberlain garage door sensors.
Necessary tools for garage door sensor adjustment
- Clean cloth
- Tape measure or a long piece of string
- A small piece of block for levelling
STEP 1: Locate the sensors
The first thing you need to do is locate the garage door sensor along the tracks.
It should be less than a foot from the ground up, and both sensors should be at the same height.
STEP 2: Turn off the garage door sensor and the garage door opener
Check the power box inside your garage and turn off the garage door sensors.
Disconnect the garage door opener from the garage door.
Open up the garage door manually.
STEP 3: Loosen the bolts that hold the sensor
Using the screwdriver, loosen the screws that hold the sensor in place.
You need a slightly spaced bracket that you can adjust in height and move around a bit.
You don’t need to take away the entire screw, you just need a loose bracket to move around.
STEP 4: Level the height of the sensors
For tape measure: Starting from the ground up, measure the height of the first sensor and mark it in the tracks.
Do the same for the second sensor and make sure they are the same height.
Adjust the mounting bracket accordingly.
For a piece of string: Tie the string to the bottom part of the first sensor.
Trace it to the other sensor and tie it on its bottom part as well.
To make sure they are on equal levels, put a piece of block in the middle of the garage door.
The string should touch the levelling block in all areas from the left to the right.
Constantly move around the block through the string’s length and find any higher spots than the block.
STEP 5: Turn on the garage door sensor
Turn on the sensor from the power box or the controls.
Check for the light beam towards the two sensors that are equally opposite each other.
A steady light beam should be present to indicate that both sensors detect each other.
Misaligned sensors won’t have a steady beam of light or have no flashing beams at all.
If the sensors are still not aligned, consider cleaning the sensors with a piece of cloth as it may cause problems.
STEP 6: Connect the garage door opener and test the garage door
Once there is a steady beam of light, connect the garage door opener to the garage door.
Do a test run and control the door using the remote control and the wall switch.
The garage door should move slowly towards the floor without issues.
