A customer called last Tuesday in a panic. Her four-year-old had placed a toy against the garage door track while it was closing. The door stopped before crushing it, but her hands were shaking as she explained what almost happened. That's when she realized her door's safety features might not be working properly. Garage door pinch points in San Rafael are real hazards that injure or kill children every year, but most homeowners don't know what stops them.
A residential garage door weighs between 300 and 600 pounds. When it closes, that force is concentrated on whatever sits in its path. Children are naturally curious. They see a moving object and want to touch it, grab it, or block it with toys. See our guide on garage door safety in san rafael: what every homeowner should know.
The worst part? Many older doors in San Rafael neighborhoods have no active safety systems at all. A door that closes on a child's arm or head moves with crushing force. Modern safety codes exist because children have been seriously hurt and killed.
Photo eyes (also called safety sensors) are infrared beams mounted on each side of the garage door opening, about 4 to 6 inches from the ground. When something interrupts that beam, the door should reverse immediately. Read about garage door cost & pricing in san rafael: what homeowners really pay.
Here's the critical part: they only work if they're clean, aligned, and actually functioning. Dust, spider webs, or misalignment can disable them without you knowing. Many homeowners think their photo eyes are protecting their family when they're actually blind.
You should test your photo eyes monthly. Block the beam with your hand while the door is closing. It should stop and reverse. If it doesn't, call Garage Door San Rafael right away. This isn't a cosmetic issue. It's the difference between a close call and a tragedy.
Walk to each sensor. Look for dirt or debris on the lens. Use a soft cloth to wipe it gently. Then close the door while watching the sensors to make sure both lights are lit (usually red or green, depending on the model). If one light is dark or flickering, you have an alignment or wiring problem.

Auto-reverse is a secondary safety system built into modern garage door openers. If the door encounters resistance while closing (like a child's hand or a toy), the opener's motor senses the extra force and reverses the door's direction.
This is different from photo eyes. Photo eyes prevent the door from starting to close. Auto-reverse stops it after it has already begun moving.
Both systems are required by law in California for residential garage doors installed after 1993. If your door doesn't have both, you're not just breaking code. You're gambling with your child's safety.
Testing auto-reverse is simple: place a 2x4 piece of wood on the ground in the door's path. Press the remote to close the door. The door should touch the wood, sense resistance, and reverse upward within one second. If it doesn't, the force sensor needs adjustment or the opener needs replacement.
Your auto-reverse and photo eyes are essential. But they're not babysitters. Children under five should never be in the garage unsupervised while the door operates. Older children need to understand that the garage door is not a toy.
One parent in Marin County told us she'd taught her six-year-old to stay away from the door's path. That knowledge, combined with working safety features, gave her peace of mind. Knowledge and equipment work together.
If you haven't tested your photo eyes and auto-reverse in the past six months, schedule an inspection. A professional can identify problems you might miss. Some issues are invisible to the naked eye. Alignment can be off by fractions of an inch and still disable your sensors.
We offer same-day estimates in San Rafael. A technician will test both safety systems, clean your sensors, and let you know if anything needs repair or adjustment. The cost of an inspection is far less than the cost of an emergency room visit.

What should I do if my garage door doesn't reverse when I place an object in its path? Stop using the door immediately. Do not attempt repairs yourself. Call a professional garage door technician to adjust the force sensor or replace the opener. This is a serious safety failure that requires expert diagnosis and repair.
How often should I test my photo eyes and auto-reverse? Test both systems monthly. Clean the photo eye lenses at the same time. Have a professional inspection at least once per year to catch alignment issues or electrical problems you can't see.
Are older garage doors in San Rafael grandfathered in from safety requirements? No. California law requires all residential garage doors, regardless of age, to have functioning photo eyes and auto-reverse. If your door is missing either system, you should upgrade your opener to meet current safety standards.
Can I install photo eyes myself? While installation is sometimes possible for homeowners with electrical knowledge, improper installation means they won't work correctly. Professional installation ensures proper alignment and electrical connection, which is critical for reliability.
What's the cost to repair or replace safety sensors? A simple sensor cleaning is often free or minimal. Replacement of one or both sensors typically costs between $150 and $300. A full opener replacement with integrated safety features runs $400 to $800, depending on the model and complexity.
