How to Fix / Troubleshooting

Safety first: Until resolved, disconnect power to the opener when away to prevent unauthorized access.

Steps to fix:

  • Inspect wall control: Check for a stuck button or moisture. Replace if the button does not return fully.
  • Remove batteries from remotes: Take batteries out of all remotes and keypads temporarily. If the problem stops, one of them has a stuck button and should be replaced.
  • Check wall control wiring: Look for shorts between the two conductors. Repair any damaged cable.
  • Clear and reprogram codes: Erase all remote codes from the opener and reprogram only your current remotes and keypads.
