Symptom-first garage door help

Garage Door Troubleshooting Guide

Start by describing what the door does, what control you used, and what changed. Try only low-risk observations; do not adjust springs, cables, bottom brackets, tracks, or electrical components.

Match the symptom to a safe next step

The door will not open

Check whether the wall control has power and whether the door appears crooked, unusually heavy, or visibly damaged. Do not force it.

Service details

The door starts, then reverses

Clear the travel path and visually check the photo-eye area. If the behavior continues, stop repeated cycling and request service.

Service details

The opener runs but the door does not move

Stop operating the opener. A disconnected or damaged door system needs inspection before further use.

Service details

The door is noisy or shakes

Note where the sound begins and whether movement is even. Grinding, scraping, cable movement, or track damage calls for service.

Useful details to share

Tell D&L the door type, visible symptom, whether the opener responds, and whether the door is stuck open, closed, or between positions. A photo of visible damage may help when requested through an approved channel.
