  If your Genie Garage Door Opener starts unexpectedly, first, inspect the wires for cuts, as staples can damage insulation and cause shorts. Replace any damaged staples or wires. Second, if a remote control has been lost or stolen, erase all remote control codes from the receiver's memory and reprogram the remaining remotes. Finally, check that no buttons are stuck in the pushed-in position on the wall console or any remote controls.

  If your Genie garage door opener isn't responding to the wall control, check the following: 1. Examine the Lock switch on the Wall Control Installation Poster. 2. Verify the power source: * For Grounded Plug Connection: Plug a lamp into the outlet. If the lamp lights, the power source is good. If not, check the fuse or circuit breaker. * For Permanent Wiring Connection: Check the fuse or circuit breaker. 3. Inspect the connections (see Wall Console Installation on Installation Poster) at the Power Head Terminals and Wall Control.
