Garage Door Sensor Repair

Sensor symptoms

• Door opens but will not close
• Opener lights flash when closing is attempted
• Sensor indicator light is off or blinking
• Door starts down and reverses

Safe checks

Clear objects from the opening, gently clean the lenses and look for obvious misalignment or damaged low-voltage wiring. Do not bypass the safety feature.

When to call

If the sensors look clear but the problem continues, the issue may involve wiring, controls, opener settings or mechanical resistance.
