Wall control LED is off and wall button does not operate the opener, but remotes still work.

Safety first: Disconnect power before working on low‑voltage wiring.

• Check console LED: If off, remove the wall console and inspect the two wires for damage or loose screws.
• Test continuity: Use a multimeter to check continuity of each conductor from the opener to the wall console. Replace damaged cable.
• Bypass test: At the opener, temporarily short the wall control terminals with a screwdriver. If the door operates, the wiring or console is faulty. Replace the Marantec wall control if wiring is good.
