Common Causes
- Broken spring
- Opener power or motor problem
- Remote or wall-control issue
- Cable or track failure
- Door locked or physically obstructed
A Quick Check
Confirm the opener has power and that no obvious object is blocking the door. If the door is heavy, crooked, or mechanically jammed, stop there and call for service.
Next Step
If the cause is not obvious, a technician can inspect the lifting system and opener together.
