Possible Causes
How to Fix / Troubleshooting
Safety first: Spring work is dangerous; do not attempt to adjust torsion springs yourself.
Check door balance:
- Disconnect the opener and lift the door manually.
- If it is very heavy or will not stay open at mid-height, springs need professional adjustment or replacement.
Adjust up force (only if door is balanced):
- Locate the UP force adjustment on the Decko opener.
- Increase slightly (1/8–1/4 turn) and test opening.
If the door is not balanced, have a garage door technician correct the springs before relying on the opener.
