Safety first: Until resolved, disconnect power to prevent unauthorized opening, especially at night.

Steps to stop unintended opening:

1. Inspect wall button: Remove the wall control and check that the button is not physically stuck. Disconnect the two wires from the back of the button and leave them separated. Restore power and monitor. If the problem stops, replace the wall control.
2. Check wiring: Inspect the wall control cable for crushed insulation or staples that may be shorting the two conductors together. Repair or replace damaged sections.
3. Reprogram codes: For older Stanley openers with dip switches, change the switch pattern on both the opener receiver and all remotes to a new, unique code. For rolling-code models, clear all remotes and reprogram only your own.
4. Test receiver: If the door still opens randomly with the wall control disconnected, the radio receiver may be faulty and responding to interference. Replace the receiver module with a Stanley-compatible or universal external receiver.

Garage door opens by itself randomly without anyone pressing a button.
