In our years serving Deming homeowners, we've seen this problem again and again: garage doors without working safety sensors. A closing door weighing 300 to 400 pounds poses serious risks to children, pets, and anyone standing beneath it. Auto-reverse and photo eye systems are the two critical safety features that stop accidents before they happen. If your door lacks these protections, you need to address it now.
Auto-reverse is a mechanical and electronic failsafe built into modern garage door openers. When the descending door encounters an obstruction, sensors trigger the motor to reverse direction immediately. This takes less than half a second. Without it, a door continues closing even if a child's hand, a pet, or a vehicle is in its path.
The auto-reverse mechanism relies on force sensors that measure resistance as the door closes. If resistance exceeds a preset threshold, the opener stops and reverses. The technology has been mandatory in U.S. garage doors since 1993, but older systems may lack proper calibration or may have worn components that no longer function correctly.
We recommend testing your auto-reverse monthly. Place a 2x4 block under the closing door. When the door touches it, the door should stop and reverse within one second. If it hesitates or doesn't reverse, contact us for a same-day safety inspection.
Photo eyes are infrared sensors mounted on both sides of the garage door frame, usually 6 inches above the ground. They create an invisible beam across the door opening. If anything breaks that beam while the door is closing, the door stops immediately.
Photo eyes catch what auto-reverse might miss. A child crawling under the door, a pet, or a bicycle left in the path will interrupt the beam and halt the door's descent. Unlike auto-reverse, photo eyes respond to presence, not force. They're especially valuable for child safety because they don't require the object to be heavy enough to trigger pressure sensors.
One common issue we find in Deming homes: misaligned photo eyes. Dust, spider webs, or accidental bumps can knock sensors out of alignment. When the beam is broken, the door won't close at all. Some homeowners assume this is a broken opener and delay repair. In reality, it's a safety feature working as designed. Keep your photo eye lenses clean and check alignment seasonally.

Auto-reverse and photo eyes work together. Photo eyes are faster and catch smaller obstructions. Auto-reverse provides a mechanical backup if photo eyes fail. Neither system is perfect alone. A malfunctioning photo eye sensor leaves you dependent on force detection. A faulty auto-reverse removes your mechanical failsafe.
Older garage doors installed before the 1990s may have neither system. If your door is over 25 years old, upgrading is worth the cost. We can discuss pricing and what a full safety upgrade looks like when you schedule a free quote.
Check your safety systems quarterly. For photo eyes: stand to the side and wave your hand across the sensor beam while the door closes. The door should stop and reverse. For auto-reverse: place a cardboard box under the closing door. Again, the door should stop and reverse on contact.
If either test fails, the sensors need adjustment or replacement. Misaligned photo eyes often just need repositioning. Faulty force sensors may require opener recalibration or component replacement. Don't ignore failed tests. A door that won't respond to obstacles is a liability.
Our team at Deming Garage Doors has serviced hundreds of safety systems across the region. We know the common failure points and can spot problems others miss. If you haven't had your safety features tested in over a year, now is the time to get an estimate.
Deming's moisture and seasonal changes can affect sensor performance. Rain and humidity corrode photo eye lenses and electrical connections. Winter moisture sometimes causes auto-reverse calibration to drift. Spring maintenance is especially important here.
Garage door safety isn't optional. It's the difference between a minor incident and a tragedy. If you're unsure whether your door has these systems or whether they're working, we offer same-day inspections and quotes. Call us at (360) 747-8783 or contact us online to schedule your safety check.
Don't wait for a close call. Have your system tested today.
What's the difference between auto-reverse and photo eyes? Auto-reverse uses force sensors to detect resistance and reverses the door when pressure exceeds a threshold. Photo eyes use infrared beams to detect any obstruction, stopping the door immediately before contact. Both are essential safety layers.
How often should I test my garage door safety features? Test both auto-reverse and photo eyes monthly. A quick 2x4 block test for auto-reverse and beam interruption test for photo eyes takes under a minute and ensures your family stays protected.
Can I adjust photo eye sensors myself? Minor alignment adjustments are possible, but if sensors aren't responding after cleaning and repositioning, professional calibration is needed. Improper adjustment can disable safety entirely.
What does a garage door safety inspection cost? A comprehensive safety inspection including sensor alignment, force calibration, and system testing typically ranges from $75 to $150. We provide a full estimate before any work begins.
Are older garage doors without photo eyes unsafe? Yes. Doors without photo eyes rely only on auto-reverse. Modern safety standards require both systems. If your door predates the 1990s, upgrading is the safest choice for child safety and liability protection.
