STOP if the door is crooked, hanging, unusually heavy, or a spring or cable appears damaged.
Do not force the door or attempt to adjust springs and cables. They can store significant force.
Safe checks first
01Check power
Confirm the opener has power and try the wall control if it is safe to do so.
02Check the obvious
Look for an obstruction in the doorway or something blocking the safety sensors.
03Listen and observe
Note whether the motor runs, clicks, hums, or whether one side of the door moves differently.
04Do not force it
If the door is heavy, uneven or the spring/cable system looks wrong, leave it in place and call a professional.
BEFORE YOU HIRE
Ask these questions.
- Is there a service-call or diagnostic fee?
- Will you quote the repair before starting?
- Are parts and labor covered by a warranty?
- If a spring failed, will you inspect the paired components and cables?
