A garage door that won’t close is both annoying and a security risk. Before you call, a few quick checks can save you time.
Start with the safety sensors
The most common cause is the photo-eye sensors near the floor. If they’re misaligned, dirty, or blocked, the door will reverse or refuse to close. Wipe the lenses, clear any clutter, and make sure both sensors point at each other with steady (not blinking) lights.
Other common causes
Other culprits include a misadjusted close-limit setting, a broken spring or cable, an obstruction in the track, a remote or wall-button issue, frozen or worn rollers, and damaged tracks. If the door is heavy or hangs crooked, stop using it — that points to a spring or cable problem that needs professional repair.
