My Wayne Dalton garage door opener, model 3790/3790z, wall mount used to open the door. The manual said that I could lock the door by using the wall mount.

When I tried to lock door, it didn't work, so in frustration I started punching all of the buttons. Now the wall mount doesn't work.

Can I fix it? How?

  • What does the manual say about doing a factory reset ?

    By "wall mount" do you mean "wall-mounted keypad"? A mount is usually attachment hardware. What are we talking about, exactly?

  • You've apparently cleared or changed the passcode. Follow the instructions to set a new code.

  • The opener that is mounted on the inside garage wall. Not the keypad.

  • In your frustration did you hit the slide switch that locks the controls ?

Unplug the opener, for at least 5-hours, to kill all power to the opener and the wall mount switch. According to Dalton, this should reset everything and put you back in business...assuming you didn't crack the wall mount's board....you'll need a new wall mount if that's the case.

  • Can I just take the batteries out?

  • I wasn't aware that it was wireless for this model, but yeah. Try and see, but it likely programmed the opener's receiving board.
