My remote control opens & closes the garage door but the button on the wall does not work.

    Is this a new installation, or one that has worked before? Has anything changed, or did the button just stop working? What is the make and model opener, and the make and model button? Do you have a multimeter, and the ability to perform basic electrical tests? – Tester101 May 26 '15 at 19:15

There are a few possibilities, you can eliminate them one by one:

Take proper safety precautions to ensure that you are not injured if the door operates while you perform the following tests

  • The wiring is loose at the opener. Depending on your opener, you may have screw terminals or push in connectors. Check that the wires are secure by gently tugging on them. (Note that most openers will have two sets of wires -- one going to the button, and another to the photocell safety mechanism. If the unit operates correctly with the remote, the ones going to the photocell are probably OK).
  • Bad wiring or button. If you have screw connectors, touch a screwdriver to the two screws that the button connects to. If you have push-in connectors, remove the wires (they may be color-coded, keep track of which is which) and briefly connect a wire to the two terminals. If the door operates, the problem is in the wire or button.
  • The button is bad. Disconnect the wires from the button and touch the bare ends together. If the door operates, either the wires weren't securely connected to the button, or it's gone bad. If the button is bad, you can replace with a like replacement, or a simple doorbell button (although you will lose the ability to control the light or turn on security mode if your button offers those features).

If you've eliminated the above, the control board in the opener may have gone bad, possibly as a result of a voltage surge. On some models, replacement boards are available online and are easy to replace. Search online for the model number of your unit for leads.

  • Some newer openers use a "smart" button that doesn't work as described above. For those, you can really only check to see if the wires are secure and if you have access to another button panel from the same model, try swapping it. – TomG Nov 14 '18 at 20:15

I replaced mine with a 50 cent doorbell button. Works fine; no more fist slamming.

A caution here. Not sure what brand garage door opener is talked about here. I have a Genie door opener and installation manual for the wall button has in "WARNING!! in BIG BOLD letters saying "Be sure Wire ends do not touch each other or other Terminals."
