Ask a Question
  • I have an Genie model 850. I need to install an electric eye. But the red light will not go off even though the alignment has been checked numerous times. The electric eye is model GSTB-R

    The red light should always be on constantly.  In other words, you should have a solid red light and a solid green light.  If neither are blinking this is normal operation and there is no other action needed.

    Please let us know if this is not the case.
