Garage Door Won't Close
Check the doorway, wall control and photo-eye alignment without defeating the opener's safety reversal system.
Keep guards, panels and safety devices in place. Stop whenever the next action needs tools, live testing, disconnection or access beyond the owner's manual.
Checks you can safely make
- Clear the entire doorway
Move people, pets, vehicles and objects away from the opening and tracks. Do not stand under a suspended door.
- Read the opener feedback
Note flashing opener lights, wall-control messages and the indicator LED on each safety sensor. The flash pattern can identify an obstruction or wiring issue.
- Clean and align photo eyes
Gently wipe both lenses and confirm the sensors face each other at the same height. Tighten only the user-adjustable bracket if the manual permits.
- Compare remote and wall control
A door that closes only while the wall button is held commonly indicates a safety-sensor problem. Do not use this as a permanent workaround.
Common questions
Why does the door reverse and the opener light flash?
That commonly means the photo-eye safety beam is blocked, misaligned or has a wiring fault. Use the model's flash-code guide.
Can I disconnect the sensors?
No. They are required safety devices and must not be bypassed.
