How to Test Your Garage Door Safety Sensors in Denver, CO (Step-by-Step Guide)
Living in Denver, CO, means dealing with high-altitude Front Range sun, wide temperature swings and wind-driven grit. These local environmental factors can take a toll on your garage door's mechanical and electronic components. At Good Golly Garage Doors Denver, we know that a malfunctioning garage door isn't just a minor inconvenience. It is a critical safety and security risk. Whether you are rushing out for your morning commute on I-75 or keeping your family secure at night, ensuring your garage door operates safely is absolutely paramount.
Your garage door is likely the largest moving object in your home, often weighing hundreds of pounds. This comprehensive guide provides expert, actionable steps to test your safety sensors, outlines vital maintenance checks, and explains exactly when it's time to schedule a professional safety inspection with our highly responsive local Denver team.
Why Does Garage Door Safety Matter in Denver?
As local garage door experts serving metro Denver, we have seen firsthand how extreme temperature fluctuations can cause tracks to warp, springs to lose tension, and safety sensors to misalign. Since 1993, federal law has mandated that all automated garage door openers be equipped with a secondary entrapment protection system, commonly referred to as "photo eyes."
These sensors transmit an invisible infrared beam across the threshold. If this beam is broken by a person, pet, or vehicle while the door is closing, the system immediately signals the opener motor to stop and reverse direction. When these sensors fail, the risk of severe property damage or tragic injury skyrockets. Regular DIY testing, combined with annual professional inspections, is the most effective way to maintain a secure, reliable, and compliant garage door system.
How to Test Your Garage Door Safety Sensors (Step-by-Step)
Testing your photo eye sensors is a straightforward process that takes only a few minutes. We highly recommend performing this test every month as part of your regular home maintenance routine.
Step 1: Clean the Sensor Lenses Before conducting any tests, take a soft, dry microfiber cloth and gently wipe the glass lenses of both sensors. Denver's dusty surroundings, especially during the dry summer months, can quickly coat these lenses in dirt. A dirty lens can scatter the infrared beam, causing false positives or preventing the sensors from working entirely.
Step 2: Check the Alignment and LED Indicator Lights Look closely at the small LED lights on both sensors. One is the sending unit, and the other is the receiving unit. Both lights should be solid and unblinking. If the receiving unit's light is flickering, dim, or completely off, the sensors are misaligned. Gently adjust the pivot bracket by hand until the light remains solid and bright.
Step 3: The Object Test Open your garage door completely using your wall console or remote. Find a solid object that is tall enough to break the beam, such as a roll of paper towels or a medium-sized cardboard box. Place this object directly in the line of sight between the two sensors, which should be mounted about six inches off the ground.
Step 4: Attempt to Close the Door Press your wall-mounted garage door button or use your remote control to initiate the closing cycle.
Step 5: Observe the Reaction
- Pass: The door should begin to close, detect the object breaking the infrared beam, stop immediately, and reverse back to the fully open position.
- Fail: If the door continues to close and crushes the object, your sensors are failing. Stop using the automatic door immediately. Disconnect the opener by pulling the red emergency release cord and operate the door manually until a professional can repair the system.

Denver safety & security FAQs
Common homeowner questions
Straight answers first: the Denver 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 test and the mechanical reversal test at least once a month. Regular testing ensures that any alignment issues, dirt buildup, or mechanical malfunctions are caught early before they become dangerous or expensive to fix.
Why is my garage door reversing when there is nothing in the way?
This is usually caused by misaligned photo eye sensors, dirty sensor lenses, or direct sunlight blinding the receiving sensor. In Denver, the intense afternoon sun can sometimes hit the sensor lens at just the right angle to mimic a broken beam. Try cleaning the lenses or checking the alignment lights.
Can I bypass the safety sensors if they are broken?
No. Bypassing safety sensors is extremely dangerous, highly irresponsible, and violates federal safety regulations. If your sensors are broken, you must operate the door manually and have the sensors repaired or replaced by a professional immediately.
How much does a professional garage door safety inspection cost in Denver?
Costs can vary depending on the age, make, and condition of your system, but a standard safety inspection and tune-up is highly affordable. It is a small investment that can save you hundreds in emergency repair costs down the line. Contact Good Golly Garage Doors Denver for a free, accurate estimate.
