Garage door opener will not respond to wall button, but remotes work normally.

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

Steps to troubleshoot:

• Test at opener terminals: Remove the wall control wires from the opener. Briefly short the two wall control terminals with a small insulated jumper wire. If the door moves, the opener is fine and the issue is in the wall control or wiring.
• Inspect wall control: Remove the wall button from the wall and check for loose or corroded connections. Replace the wall control if the button is physically damaged.
• Check wiring run: Follow the cable from opener to wall, looking for staples through the wire or cuts. Replace damaged cable.
• Reconnect and test: Attach the repaired or new wall control and test operation.
