Hi, Welcome to JustAnswer.com, I am glad you are here! My name is Eric & I will endeavor to answer your question.
Disconnect the wire to the pushbutton from the circuit board. Let it sit a while to see if it opens on its own without the wiring connected. If it does, you need to replace your circuit board. If not, reconnect the wire to the circuit board and disconnect it from the push button. Now see if the gate opens by itself. If not, rewire to the push button and see if the problem continues. If Yes, replace your push button. If the gate opens by itself with the push button disconnected, replace the wire form the opener to the push button in its entirety. If your wiring is buried or in walls, conduit or otherwise difficult to replace, you may do the test by running new wire right across the drive, swail or yard from the control panel to the push button. Disconnect the old wire and connect the new wire at the circuit board and push button (even though not yet run on the correct path). If the gate works fine and does not open on its own after that, you will have to do a permanent wire replacement.

If you disconnect the wire to the push button from the control board and the problem goes away, it could mean that either the push button is bad or the wire between the push button and the control board is bad.
Disconnect the wire from the button and reconnect the wire to the control panel. If the problem returns without the button being attached, it is probably the wire. If the problem does not return with the wire (but not the button) hooked up, then re-attach the button to the wire. if the problem then returns, then the problem was the button.
