FAQ Garage Door safety sensors
-
Why won’t my garage door close?
Your garage door safety sensors may be blocked, misaligned, dirty, or damaged. If the sensors can’t communicate, the opener will prevent the door from closing for safety.
-
How do I know if my safety sensors are bad?
Blinking indicator lights, a door that reverses before closing, or a garage door that only closes when you hold the wall button are common signs of faulty safety sensors.
-
Can garage door safety sensors be repaired?
Yes. Many sensor problems can be fixed by cleaning, realigning, or repairing damaged wiring. If the sensor has failed, replacement is usually the best option.
-
Do both sensors need to be replaced?
Not always. If only one sensor is defective, it can often be replaced individually. Our technician will inspect both sensors before making a recommendation.
-
How much does garage door sensor repair cost?
The cost depends on whether the issue is alignment, wiring, or a failed sensor. We provide an upfront estimate before any work begins.
-
Can I clean or align the sensors myself?
You can gently clean the sensor lenses and check for obvious misalignment. If the problem continues, professional diagnosis is recommended to avoid damaging the system.
-
Why is one sensor light blinking?
A blinking light usually indicates the sensors are out of alignment, obstructed, or have a wiring issue that prevents proper communication.
-
How long does sensor replacement take?
Most garage door safety sensor repairs or replacements are completed in less than one hour, depending on the opener model and the condition of the wiring.
