Door closes then immediately opens a short distance (bounces back) without any beeping or flashing.

Safety first: Keep people and pets clear while testing.

• Inspect floor and seal: Check for raised concrete, high thresholds, or objects under the door. Ensure the bottom seal is flexible and not folded.
• Adjust down force: Reduce the DOWN force setting slightly on the Merlin opener (via dials or menu). Too much force can cause the safety system to react.
• Check door alignment: Ensure the door meets the floor evenly across its width. Adjust track brackets or call a door technician if the floor is uneven.
• Retest: Run several close cycles and confirm the door stays closed without reopening.
