Frequently Asked Questions (FAQs)
Your garage door sensors are working if the door closes and reverses when something blocks the beam. Blinking lights or random reversals may signal a problem. If the door won’t close or opens by itself, check the sensor lights. If they blink red or yellow, the sensors may be misaligned or malfunctioning.
If your garage door won’t close fully, the safety sensors might be blocked, dirty or misaligned. These sensors are designed to stop the door if something is in its path. Cleaning the sensor lenses or adjusting their alignment may fix the problem. If not, it is best to call a professional for troubleshooting.
Flashing red or yellow lights on your garage door sensors usually mean trouble. This can happen if the sensors are not aligned, the beam is blocked or there is a wiring issue. These lights are warning indicators that the safety system is not functioning correctly.
Garage door safety sensors should be installed about 4 to 6 inches above the ground. This height helps the beam spot small objects, pets or kids. It stops the door from closing if anything is in the way.
Try simple fixes, like cleaning the sensors. You can also gently adjust their alignment. If the problem is with electricity, wiring or a sensor, call a certified technician. This way, you can be sure everything meets safety standards.
Installing or repairing garage door sensors usually costs between $75 and $200. This price varies based on the problem and the type of sensor. Crestline provides free estimates. Our pricing is clear and upfront, so there are no hidden fees.
Yes. Since 1993, federal law requires all automatic garage doors in the U.S. to have a safety reverse system and working safety sensors. If your sensors do not work, your system might not meet legal requirements. This could be risky.
To test your sensors, place an object (like a cardboard box) in the sensor beam path and try closing the door. The door should stop and reverse. If it does not work, the sensors might be dirty, misaligned or broken. They may need a professional check-up.
Test your safety sensors every month. Also, have a professional do a full inspection each year. Regular maintenance ensures your garage door system remains safe, reliable and legally compliant.
