In the meantime, a door that has come off its track or has a broken spring should not be operated at all, by hand or with the opener. DASMA's guidance for a homeowner checking a damaged door is explicit that if a problem is found, the inspection should stop and a trained technician should be called rather than the door being worked on.

Checked 31 August 2026. If the door is closed and the car is inside, see [the emergency page](https://gd-concept.pages.dev/services/emergency-garage-door-repair/) for how to release the opener safely, and what not to do afterwards. ## Commercial property?
