A customer called last Tuesday after her son nearly got pinched by a closing door. She'd owned the home for three years, never checked the safety sensors, and didn't know her opener lacked auto-reverse capability. That call stuck with me because it happens more often than it should. Garage door safety in Greenbank isn't complicated, but it does demand attention. Your door weighs 300 to 400 pounds and moves fast. One missing safety feature can turn routine use into a serious injury.
Your garage door has two independent safety layers. The first is the auto-reverse mechanism on your opener. If the door encounters resistance while closing, it should reverse direction within two seconds. This is mechanical and electrical redundancy working together. The second layer is the photo eye, or safety sensor. These infrared beams sit about six inches above the floor on each side of the opening. If anything breaks the beam while the door closes, the door stops and reverses. See our guide: Garage Door Opener Safety Features in Greenbank.
Both systems must work correctly. A broken photo eye is invisible until something goes wrong. The door closes normally, but without that final safety net. Dust, spider webs, or misalignment can block the beam. Many homeowners in Greenbank and the surrounding Puget Sound region don't test these sensors monthly, which is the standard recommendation.
Here's what you do. Close your garage door halfway, then wave your hand through the beam on either side. The door should reverse immediately. If it doesn't, stop using the door and call a professional same-day. Don't bypass the sensors or tape them open, even temporarily. That removes the protection entirely. See our guide: Garage Door Openers in Greenbank.
If your opener is more than 15 years old, it likely doesn't have modern safety sensors at all. Openers built before the 1990s sometimes relied only on mechanical resistance, which is far less reliable. If that describes your situation, read our guide to garage door opener safety features in Greenbank) to understand what a newer system provides.

Garage door springs last 7 to 9 years on average, depending on use. Mark your calendar for inspection when yours approaches that age.
Monthly testing takes five minutes. Walk around your door. Look for frayed cables, rust on the springs, or bent tracks. Feel the door's balance by disconnecting the opener and manually lifting the door halfway. It should stay in place. If it drifts down, the spring tension is uneven and needs adjustment.
Some repairs are simple. Others are not. If your photo eye is misaligned, we can realign it quickly and verify the fix works. If your auto-reverse isn't responding, the opener's logic board or safety circuit may need replacement. These aren't jobs for a homeowner.

What's the difference between auto-reverse and photo eye safety? Auto-reverse stops the door if it hits something during closing. Photo eye is a backup that stops the door before it makes contact. Both systems must work for full protection. One failing leaves you vulnerable.
How often should I test my garage door safety sensors? Test your photo eyes monthly by walking through the beam while the door closes. The door should reverse immediately. Also visually inspect the sensors for dust or damage every month.
