I have replaced the battery on reprogrammed the remotes with no luck.
Garage door won t open from outside with remote.
Check to be sure the antenna is attached and if it is not hanging down from the unit move the antenna so it can catch the beam being sent by the remote.
Unplug the opener and disconnect the two wires from the motor reconnect your machine to power then clear its memory and reprogram all remote controls unplug the device for a second time and reconnect the control wiring to.
If that doesn t work and you still have a nonworking remote you may want to have a professional examine it.
Press the button as you observe a small blinking red light on the box where the chain enters and exits.
Try installing a new battery and attempt to open the door again with the remote.
You can also try pushing the garage door button on the wall.
Quickly test the quality of your opener s wiring by following these steps.
My garage door remotes will not open door from the outside unless you are right in front of the door.
Both remotes will open door from inside garage as will wall switch.
