During this process the two door openers might get confused.
My garage door remote opens two doors.
The remotes transmits a code to the receiver on the power head then the receiver sends a signal back asking for a code from the remote.
If your garage door is closing fully and then reversing to open again then it may be due to a problem with the close limit switch.
Problem here is that it opens the second garage door opener just fine for a day or so.
Then within a couple of days open close the garage door a few times with it it starts opening the first door.
When this happens the two do not always open at the same time.
First unplug the first unit and program the linksys.
If this does not fix the situation then you may need to replace the garage door opener or the circuit board to get to a different frequency.
In order to fix this you ll want to make small changes to the close limit setting until the door opener knows to stop once the door has reached the floor.
These remotes have three positions allowing you to open as many as three doors from one remote.
If your neighbors garage door remote is opening your garage door the first thing to do is reset the codes using the dip switches or learn button.
It s a really a bummer we click it to close the second door and at the same time the first door starts to open.
Examine the garage door opener button.
The other garage door is an old opener probably pre 1993 and has worked fine until now.
Unplug the device for a second time and reconnect the control wiring to the motor.
Wcchuckers stated the solution unplugging the garage door opener is the trick.
I used only one remote to program both buttons.
Unplug the opener and disconnect the two wires from the motor.
When i press the wired button to my new liftmaster it sometimes not always will open the other garage door that has the old opener as well as the liftmaster door itself.
It all depends on the configuration but you likely have a button that activates the door operator.
The button can easily get dirty and stuck in the pushed.
The door operator button is similar to a door bell.
To troubleshoot the garage door opener button make sure it s clean and free of debris.
Reconnect your machine to power then clear its memory and reprogram all remote controls.
The remote then transmits the code.
