The opener does not respond to the wall button; remotes may still work; the diagnostic LED flashes seven times repeatedly.

Safety first: Turn off power before working on control wiring. Low-voltage circuits can still short and damage the logic board.

Steps to diagnose the wall control:

• 1. Inspect wall console: Remove the Stanley wall button or console from the wall. Check that the two low-voltage wires are firmly attached to the terminals and not corroded.
• 2. Test with jumper: At the opener head (power off), remove the two wall control wires from the P/B or WALL terminals. Restore power. Briefly short the two terminals with an insulated screwdriver. If the opener runs, the wall control or its wiring is faulty.
• 3. Check cable run: With power off again, inspect the wall control cable along the ceiling and wall for staples through the insulation or visible damage. Replace any damaged sections with new bell wire.
• 4. Replace wall console: If wiring is intact but the console does not operate the door, install a new Stanley-compatible wall button or multi-function console and connect it to the same two terminals.
