A door that reverses before reaching the floor can be responding to a safety sensor, obstruction, travel issue, or mechanical resistance.
Safe observations
- Clear the opening
- Inspect sensor lenses for obvious dirt
- Look for track obstructions
- Do not bypass safety systems
See sensor repair, won’t close, or opener repair.
