Door opens or closes only a short distance then stops, no code shown

Safety first: Ensure the door path is clear before running learning cycles.

Step-by-step:

• Reset programming: Follow the Hormann manual to reset the operator to factory settings if necessary.
• Set limits: Enter programming mode and set the open and close positions exactly as instructed, allowing the operator to run full travel.
• Do not interrupt: Let the operator complete its automatic learning cycle without cutting power or pressing other buttons.
• Test: After programming, run several full cycles to confirm consistent travel.
