Possible Causes
Bent track, Damaged roller, Door panel hitting frame, Loose hinge causing binding
How to Fix / Troubleshooting
Safety first: Disconnect power and use the manual release. A binding door can suddenly free itself.
Step-by-step:
- Operate manually: Disengage the operator and move the door by hand. Note any tight spots or points where it sticks.
- Inspect tracks: Look for bends, dents, or misalignment in the vertical and horizontal tracks. Gently straighten minor bends; replace severely damaged sections.
- Check rollers: Spin each Hormann roller by hand. Replace any that are seized, wobbly, or cracked.
- Examine hinges and brackets: Tighten loose hinge screws and track bracket bolts. Replace bent hardware.
- Re‑engage operator and test: After correcting mechanical issues, reconnect the operator and run a full cycle.
