Just installed two Craftsmans G-Door Openers. One is operating fine the other seems to go up on its own during the day. My Area is still under construction and am wondering if trucks going by can set it...
Look at the LED light next to the
SMART/LEARN button on rear of the motor unit. You may need to remove
a light lens cover in order to see it. If the light is flashing
rapidly this means you have a stuck button on one of your remote
controls. Take the batteries out of each remote control. When you
remove the batteries from the bad remote, the light will stop
flashing. This remote needs to be replaced.
If one of your neighbors remote
controls is inadvertently programmed into your receiver, you door
will open when their remote is activated. If this happens you will
need to clear out your receiver and reprogram your remote controls.
Press and hold the smart/learn button for 6 seconds or until you see
the small LED light near the button turn itself off. If the above
steps have been followed and the symptoms continue, there may be an
electronic short in either the wall control button or the receiver
logic board. In this case, remove the wall control wires from
terminals 1 and 2 on the motor unit. Should the symptoms persist
after the wires are removed, replace the receiver logic board. If the
symptoms stop with the wall control wires removed from the motor
unit, replace the wall control button, and the wires leading to the
wall control button.
