How to Test Your Garage Door Safety Sensors in Decatur, AL (Step-by-Step Guide)
Your garage door is likely the largest moving object in your home, weighing hundreds of pounds. Ensuring it operates safely is not just about convenience; it's about protecting your family, pets, and vehicles from severe injury or damage. At Good Golly Garage Doors in Decatur, AL, we prioritize your safety above all else.
Living in North Alabama means our homes are subjected to intense summer heat, high humidity, and the occasional severe thunderstorm. These local environmental factors can take a toll on your garage door's delicate electronic components, particularly the safety sensors. A power surge from a storm or subtle shifting due to temperature changes can easily knock your sensors out of alignment.
As local experts serving Morgan County, we highly recommend that every homeowner knows how to perform basic safety checks. In this guide, we will walk you through the exact steps to test your garage door safety sensors and explain when it's time to call in the professionals for a comprehensive safety inspection.
Why Are Garage Door Safety Sensors Crucial?
Since 1993, federal law has required all automated garage doors to be equipped with a safety reversing mechanism. The most common system uses photoelectric sensors, often called "photo eyes", located about six inches above the floor on either side of the garage door opening.
These sensors shoot an invisible infrared beam across the opening. If anything breaks that beam while the door is closing, the system immediately halts the door's downward progress and reverses it.
In Decatur, the combination of high humidity and dust can sometimes obscure the sensor lenses, while accidental bumps from lawnmowers or bicycles can misalign them. When these sensors fail, the heavy door becomes a significant hazard. That's why regular testing is a non-negotiable part of home maintenance.
How to Test Your Garage Door Safety Sensors (Step-by-Step)
Performing a safety test is quick, easy, and requires no special tools. We recommend doing this once a month. Here is the step-by-step process used by our Good Golly Garage Doors technicians:
Step 1: Visual Inspection and Cleaning
Before testing the mechanics, inspect the sensors themselves.
- Locate the Sensors: Find the two small devices near the bottom of your garage door tracks.
- Check the Lights: Both sensors should have a solid, unblinking indicator light (usually one green and one yellow or red, depending on the brand). If one light is blinking or off, the sensors are misaligned or not receiving power.
- Clean the Lenses: Use a soft, dry microfiber cloth to gently wipe the lenses. Decatur's pollen and dust can easily build up and block the infrared beam.
Step 2: The Object Reversal Test
This test ensures the door reverses when an object is in its path.
- Open the Door: Start with the garage door fully open.
- Place an Obstruction: Place a solid object, like a roll of paper towels or a cardboard box, directly in the path of the door, breaking the invisible beam between the two sensors.
- Close the Door: Press your remote or wall button to close the door.
- Observe the Reaction: The door should not move downward at all. Instead, the opener lights may flash, or you may hear a clicking sound indicating the path is blocked. If the door begins to close and crushes the object, your sensors are failing and require immediate professional attention.
Step 3: The Moving Object Test
This ensures the sensors react quickly to sudden movement.
- Clear the Path: Remove the object from the previous test.
- Close the Door: Press the button to close the door.
- Break the Beam: While the door is moving downward, carefully wave a broom handle or a long stick in front of one of the sensors to break the beam.
- Observe the Reaction: The door should immediately stop and reverse direction. If it continues to close, the sensors are defective.
Step 4: The Mechanical Force Setting Test
Even if the photo eyes work, the door's mechanical force setting must also be tested to ensure it reverses upon physical contact.
- Place a Block: Place a 2x4 piece of wood flat on the ground in the center of the garage door opening.
- Close the Door: Press the button to close the door.
- Observe the Reaction: When the door hits the wood, it should automatically reverse within two seconds. If it stops and rests on the wood without reversing, the force settings need adjustment.
When Should You Call Good Golly Garage Doors in Decatur?
If your garage door fails any of the tests above, it is unsafe to operate. Disconnect the automatic opener by pulling the red emergency release cord and operate the door manually until it can be repaired.
Attempting to fix complex electrical issues or adjust the heavy torsion springs yourself can lead to severe injury. Our Decatur-based technicians at Good Golly Garage Doors are fully trained, background-checked, and equipped to handle these repairs safely. We understand the local architecture and the specific wear-and-tear patterns common in North Alabama homes.
Signs you need a professional inspection:
- The sensor lights remain off or continuously blink despite cleaning and manual realignment.
- The door fails the object reversal or force setting tests.
- The door makes grinding, scraping, or unusually loud noises during operation.
- The door operates inconsistently or seems to struggle when opening or closing.

Decatur safety & security FAQs
Common homeowner questions
Straight answers first: the Decatur team can go deeper on anything specific to your door, your opener, and your home.
How often should I test my garage door safety sensors?
You should perform the DIY safety sensor tests at least once a month. Additionally, we recommend scheduling a professional safety inspection and tune-up with Good Golly Garage Doors in Decatur at least once a year to ensure all components are functioning optimally.
Why are my garage door sensors blinking?
Blinking sensor lights usually indicate that the photo eyes are misaligned or that something is obstructing the infrared beam. It can also be caused by dirty lenses, loose wiring, or direct sunlight blinding the sensor. Try cleaning the lenses and gently adjusting them until the light becomes solid.
Can I bypass the safety sensors if they are broken?
No. Bypassing the safety sensors is extremely dangerous and violates federal safety regulations. If your sensors are broken, the door should only be operated manually until a professional technician can repair or replace the sensor system.
How much does a professional garage door safety inspection cost in Decatur, AL?
The cost of a safety inspection is minimal compared to the peace of mind it provides, typically ranging from $300 to $600. At Good Golly Garage Doors, our inspections are comprehensive and transparent, with no hidden fees. Contact our Decatur location for the most accurate and up-to-date pricing.
Will severe Alabama weather affect my garage door sensors?
Yes. High humidity can cause condensation on the sensor lenses, while heavy rain and lightning can cause power surges that damage the electrical components. After a severe storm in Decatur, it is always a good idea to test your garage door to ensure the sensors are still functioning correctly.
