Every electric garage door opener sold today uses a pair of photo-eye safety sensors mounted near the bottom of the tracks. One sensor sends an invisible beam to the other. If anything breaks that beam while the door is closing, the opener reverses the door. It is one of the most important safety features in your garage, and it is also one of the most common reasons a door will not close.
Sensor Problems GDS-RepairParkRidgeIL Solves
- Misalignment. A bump from a bike, bin or car can knock a sensor out of line.
- Dirty lenses. Dust, cobwebs and moisture can block the beam.
- Bright sunlight. Direct sun on the receiving sensor can confuse it at certain times of day.
- Damaged wiring. Staples, rodents or wear can break the low-voltage wires.
- Failed sensors. Older sensors simply wear out and need replacement.
Signs your sensors need attention
The door goes down a few inches and then back up. The opener light flashes. The door only closes if you hold the wall button down. Any of these signs means the opener is not getting a clear signal from its sensors.
Never bypass the sensors
Some people tape over or disconnect sensors to get the door to close. This removes the protection that keeps children, pets and vehicles safe. Our technicians fix the real problem, then test the auto-reverse feature to be sure it works properly.
