Safety Warning

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Down force set too low, Door slightly binding near closed position, New bottom seal increasing resistance, Worn rollers causing extra friction

How to Fix / Troubleshooting

Safety first: Never increase force to overcome a heavy or damaged door. Fix mechanical issues first.

Steps to try:

Check door movement: Disconnect the opener and move the door manually. It should close smoothly without sticking.
Inspect bottom seal: If a new seal was installed, ensure it is not excessively stiff or too long.
Adjust down force: On the Novoferm control board, slightly increase the down force setting within the recommended range. Test by closing the door and confirming it stops and reverses properly when encountering a solid object.
