Re: Garage door remote control constantly transmitting??



Make sure the obstacle beam "windows" are clean and the
beam is properly aimed at the sensor on the opposite side of
the door opening.  The problem symptom is typical for
dirty beam sensor windows.

Depending on the design of the housing for the sensing device,
disassembly may be required to clean both sides of the beam windows.
