I have a push button mounted on the stud next to the garage door. The electrical wires are correctly connected to the push button and to the garage-door opener because, when I push the button, the garage door opens and closes.
The push button has suffered a dent so it needs to be replaced.
I have bought a new push button and attached the wires correctly.
Now, when I push the button, the garage door goes up. But, when I push the button again. the door doesn't go down unless I disconnect and reconnect the wires.
Apparently, I bought the wrong type of push button. What kind of push button do I need to buy?
