Display shows F10; opener will not respond to wall button or remotes.

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

• 1. Check wall station lock: On Linear multi-function wall consoles, verify that the lock or vacation mode is not enabled. Press and hold the lock button (if present) for several seconds to toggle it off.
• 2. Test with jumper: At the opener, disconnect the wall control wires. Briefly short the wall control terminals with a small insulated jumper wire. If the door operates, the wall station or its wiring is faulty.
• 3. Inspect wall control wiring: Look for staples driven too tightly, cuts, or crushed cable between the opener and wall station. Repair or replace damaged wire.
• 4. Replace wall station: If wiring is good and the opener responds to a jumper but not the wall console, replace the Linear wall control with a compatible model.
• 5. Verify terminal connections: Ensure the wall control wires are on the correct terminals at both the opener and the wall station per the Linear wiring diagram.
