Garage door opens by itself without any command from remotes or wall button.

Safety first: Until resolved, disconnect power to the opener when away to prevent unintended opening.

Steps to troubleshoot:

• Inspect wall control: Check if the wall button is sticking or physically jammed. Replace if necessary.
• Disconnect wall control wiring: Temporarily remove wall control wires at the opener. If random openings stop, the issue is in the wall control or wiring.
• Check remotes: Remove batteries from all remotes and keypads. If the problem stops, inspect remotes for stuck buttons.
• Change remote codes: Clear all remote codes from the opener and reprogram using a new code sequence to avoid interference from neighboring units.
• Replace logic board if needed: If the opener still activates with all inputs disconnected, the logic board may be defective and should be replaced.
